Electronic alerts to prevent venous thromboembolism among hospitalized patients.

BACKGROUND: Prophylaxis against deep-vein thrombosis in hospitalized patients remains underused. We hypothesized that the use of a computer-alert program to encourage prophylaxis might reduce the frequency of deep-vein thrombosis among high-risk hospitalized patients. METHODS: We developed a computer program linked to the patient database to identify consecutive hospitalized patients at risk for deep-vein thrombosis in the absence of prophylaxis. The program used medical-record numbers to randomly assign 1255 eligible patients to an intervention group, in which the responsible physician was alerted to a patient's risk of deep-vein thrombosis, and 1251 patients to a control group, in which no alert was issued. The physician was required to acknowledge the alert and could then withhold or order prophylaxis, including graduated compression stockings, pneumatic compression boots, unfractionated heparin, low-molecular-weight heparin, or warfarin. The primary end point was clinically diagnosed, objectively confirmed deep-vein thrombosis or pulmonary embolism at 90 days. RESULTS: More patients in the intervention group than in the control group received mechanical prophylaxis (10.0 percent vs. 1.5 percent, P<0.001) or pharmacologic prophylaxis (23.6 percent vs. 13.0 percent, P<0.001). The primary end point occurred in 61 patients (4.9 percent) in the intervention group, as compared with 103 (8.2 percent) in the control group; the Kaplan-Meier estimates of the likelihood of freedom from deep-vein thrombosis or pulmonary embolism at 90 days were 94.1 percent (95 percent confidence interval, 92.5 to 95.4 percent) and 90.6 percent (95 percent confidence interval, 88.7 to 92.2 percent), respectively (P<0.001). The computer alert reduced the risk of deep-vein thrombosis or pulmonary embolism at 90 days by 41 percent (hazard ratio, 0.59; 95 percent confidence interval, 0.43 to 0.81; P=0.001). CONCLUSIONS: The institution of a computer-alert program increased physicians' use of prophylaxis and markedly reduced the rates of deep-vein thrombosis and pulmonary embolism among hospitalized patients at risk.

Complications of inguinal and pelvic lymphadenectomy for squamous cell carcinoma of the penis: a contemporary series.

PURPOSE: We examined complications in a contemporary population of patients with penile cancer undergoing inguinal lymphadenectomy with or without pelvic lymphadenectomy. MATERIALS AND METHODS: The records of all patients treated for squamous cell carcinoma of the penis from January 1992 to May 2003 were reviewed. Complications and length of stay were examined. Complications were divided into early (30 days or less after surgery) and late (greater than 30 days). RESULTS: A total of 41 men were diagnosed with squamous cell carcinoma of the penis, of whom 22 underwent a total of 40 inguinal lymphadenectomies (ILs). Of the patients 13 underwent unilateral IL, 9 underwent simultaneous bilateral ILs and 10 underwent pelvic lymphadenectomy. Mean followup was 34.2 months (range 9.2 to 69.3). Early complications were lymphedema in 4 of 40 cases (10%), minor wound infection in 3 (7.5%) and minor wound separation in 3 (7.5%). Additionally, 5 of 40 patients (12.5%) had lymphoceles, which spontaneously resolved. Late complications were lymphedema in 2 of 40 patients (5%), flap necrosis in 1 (2.5%) and lymphocele in 1 (2.5%), requiring percutaneous drainage. There was no significant difference in the complication rates in patients with unilateral dissection compared to bilateral or pelvic lymph node dissection. Median length of stay was 2 days (range 1 to 9). There was no significant difference in hospital stay for unilateral dissection compared to bilateral or pelvic lymph node dissection. CONCLUSIONS: These data demonstrate the relative safety of a contemporary lymphadenectomy. We believe that these results lend support to early lymphadenectomy, including simultaneous bilateral dissections, when clinically indicated. Furthermore, these results demonstrate the benefits of a standard postoperative pathway using compression stockings, sequential compression devices and early ambulation with restricted anticoagulant use.

The treatment of ambulatory venous ulcer patients with warming therapy.

The standard treatment for ambulatory patients with venous ulcers is compression therapy. The aim of the present study was to develop a warming regimen to treat venous ulcers, which could be easily used by patients in their home or work environment. Five patients with a mean age of 66 years (51-80) who had venous ulcers for an average of 8 months (3-13) were treated with zip-up compression stockings (gradient compression 40 mmHg at the ankle) and a warming dressing. The latter was controlled by the patient to warm the ulcer to 38 degrees C for 1 hour three times daily. Warming therapy was carried out for 2 weeks and patients' ulcers were monitored for healing for 12 weeks. In all but one of the patients following warming therapy, there was marked increase in granulation tissue as well as a decrease in pain. Four of the five patients completely healed during the 12-week period. In conclusion, this study has demonstrated that warming therapy can be used by ambulatory patients with venous ulcers in conjunction with compression therapy. A randomized prospective study is in progress.

Non-pharmaceutical measures for prevention of post-thrombotic syndrome.

BACKGROUND: Post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis (DVT) characterised by chronic pain, swelling and skin changes in the affected limb. One in every three patients with DVT will develop post-thrombotic complications within five years. OBJECTIVES: To determine the relative effectiveness of, and the rate of complications using non-pharmaceutical interventions in patients with DVT in the prevention of PTS. SEARCH STRATEGY: The reviewers searched the Cochrane Peripheral Vascular Diseases Group Specialised Trials Register (last searched January 2003), and the Cochrane Central Register of Controlled Trials (CENTRAL) (last searched Issue 4, 2002). In addition, hand searching of non-listed journals and personal communications with researchers was undertaken. SELECTION CRITERIA: Randomised controlled trials (RCTs) of non-pharmaceutical interventions, such as bandaging and elastic stockings in patients with clinically confirmed DVT. The primary outcome was the occurrence of PTS. There was no restriction on date or language. One reviewer (DNK) identified and assessed titles and abstracts for relevance. This was verified independently by a second reviewer (RS). DATA COLLECTION AND ANALYSIS: Data extraction was undertaken independently by two reviewers (DNK, RS), using data extraction sheets. MAIN RESULTS: Three RCTs that evaluated compression therapy were identified. Two studies compared elastic compression stockings with a pressure of 30-40 mm Hg at the ankle with no intervention applied directly after an episode of DVT. The other small study compared elastic compression stockings (pressure 20-30 mm Hg) with stockings that were one to two sizes too large in patients one year after DVT. Overall, in the treatment group at two years, the use of elastic compression stockings was associated with a highly statistically significant reduction in the incidence of PTS with odds ratio (OR) 0.31 (95% confidence interval (CI) 0.20 to 0.48). In addition, the incidence of severe PTS was reduced from OR 0.39 (95% CI 0.20 to 0.76). In another RCT that considered the first nine days post DVT, no difference in the incidence of pulmonary embolism and size of thrombus in the femoral vein was found. A statistically significant reduction (p <0.05) was found in pain, swelling and clinical scores, favouring the compression group. REVIEWER'S CONCLUSIONS: There is substantial evidence that elastic compression stockings reduce the occurrence of PTS after DVT. No serious adverse effects were mentioned in the studies. Hence, elastic compression stockings should be added to the treatment of DVT to prevent the development of post-thrombotic syndrome.

Does thigh compression improve venous hemodynamics in chronic venous insufficiency?

OBJECTIVE: The aim of this study was to investigate the hemodynamic effects of thigh compression in patients with deep venous incompetence. PATIENTS AND METHODS: This diagnostic test study was set in a municipal general hospital. Twelve patients with venous leg ulcers (CEAP classification, C6 Es Ad Pr; four men and eight women), with a mean age of 56.5 +/- 16.8 years, with popliteal venous reflux of more than 1 second detected with duplex scan, underwent investigation with the following methods: 1, the pressure exerted under thigh-length compression stockings class II and short-stretch adhesive compression bandages was measured with an MST tester (Salzmann, Switzerland) and a CCS 1000 device (Juzo, Germany), respectively; 2, the great saphenous vein and the femoral vein on the thigh were compressed with a pneumatic cuff (0, 20, 40, and 60 mm Hg) containing a window through which the diameters of these veins could be measured with duplex ultrasonography; and 3, with the same thigh-cuff occlusion procedure, the venous filling index (VFI) for each experiment was measured with air plethysmography. These values reflected the presence and extent of venous reflux in each experiment depending on the degree of venous narrowing. RESULTS: The mean pressure of a class II compression stocking was about 15 mm Hg at the thigh level, and adhesive bandages achieved a pressure of more than 40 mm Hg in the same location. A statistically significant reduction of the diameters of the great saphenous vein and the femoral vein could be obtained only when the cuff pressure on the thigh was equal to or higher than 40 mm Hg (P <.001). A reduction of the venous reflux (VFI) was achieved only with a thigh pressure of 60 mm Hg (P <.001). No significant reduction was seen of VFI with a thigh pressure in the range of the class II stockings. Previous investigations have shown that, in patients with deep venous incompetence, a pressure cuff on the thigh with 60 to 80 mm Hg is able to reduce ambulatory venous hypertension. CONCLUSION: Thigh compression as exerted with class II thigh-length compression stockings is not able to significantly reduce venous diameter or venous reflux. However, with a pressure of 40 to 60 mm Hg on the thigh that can be achieved with strongly applied short-stretch bandages, considerable hemodynamic improvement, including reduced venous reflux, can be obtained in patients with severe stages of chronic venous insufficiency from deep vein incompetence. The practical value of these preliminary findings should be investigated with further clinical trials.

The efficacy and safety of a coumarin-/troxerutin-combination (SB-LOT) in patients with chronic venous insufficiency: a double blind placebo-controlled randomised study.

BACKGROUND: The objective was to evaluate the oedema-protective effect of a vasoactive drug (coumarin/troxerutin [SB-LOT]) plus compression stockings in patients suffering from chronic venous insufficiency after decongestion of the legs as recommended by the new guidelines. PATIENTS AND METHODS: 231 patients were randomly assigned medical compression stockings plus SB-LOT (90 mg coumarin and 540 mg troxerutin per day) or medical compression stockings plus placebo for the first 4 weeks and SB-LOT or placebo for the second 12 weeks of the study. The primary efficacy endpoint was the lower leg volume measured by well-established water plethysmometry. RESULTS: 226 patients were evaluated. After ceasing compression stockings, an edema protective effect was detected in the SB-LOT-group but not in the controls. Recurrence of leg volume increase was by 6.5 +/- 12.1 ml and by 36.7 +/- 12.1 ml in the SB-LOT and placebo group, respectively (p = 0.0402). The local complaint score and general aspects of quality of life were also superior for the SB-LOT-group (p = 0.0041). Significant differences were also observed with regard to clinical global impression and therapeutic effect. No serious adverse drug reaction or clinically relevant impairment of laboratory parameters occur. CONCLUSION: This study confirms the oedema-protective effect of SB-LOT in chronic venous insufficiency and provides a treatment option for patients who discontinue compression after a short time.

The effect of graded compression elastic stockings on the lower leg venous system during daily activity.

PURPOSE: We evaluated the effects of wearing 20 to 30 mm Hg gradient thigh-length stockings during daily activity on the lower leg venous system. METHODS: Twenty-one healthy women volunteers, aged 39 +/- 12 years, were examined. One subject was clinical class 4, one was class 2, two were class 1, and the remainder were class 0. The diameter of the posterior tibial, peroneal, and greater saphenous veins were measured at midcalf by means of bilateral duplex ultrasound scanning; calf circumference was measured at the same level. In addition, the number and caliber of all detectable medial calf perforating veins were recorded. Each subject was examined on two separate days, one while wearing the gradient stockings and one not wearing them. Baseline measurements were made on each day before the subjects began their workday, with follow-up measurements made after approximately 4.5 hours of normal activity. RESULTS: Calf circumference increased an average of 23.8 +/- 10.1 mm without stockings (P <.001) and decreased by 5.2 +/- 7.0 mm when wearing stockings (P =.003). The number of detected perforating veins increased without stockings by 1.8 +/- 2.0 at the follow-up examination (P =.002); with stockings, the change was 0.4 +/- 1.2 (P = NS). CONCLUSION: Graded compression elastic stockings help preserve lower leg venous caliber and tone throughout the deep, superficial, and perforating venous systems during normal ambulatory activity, and this may, in part, explain their beneficial effects.

[Prospective study of the risk factors for the development of post-thrombotic syndrome after proximal deep venous thrombosis].

BACKGROUND AND OBJECTIVE: The incidence and risk factors for the development of post-thrombotic syndrome (PTS) are not well known, so the aim of our study is to evaluate the development of PTS after proximal deep vein thrombosis (DVT) and its relationship with several clinical, laboratory and therapeutic factors. PATIENTS AND METHOD: Prospective, observational study. INCLUSION CRITERIA: consecutive patients with acute symptomatic proximal DVT in the lower extremities diagnosed between February 2000 and July 2002. EXCLUSION CRITERIA: life expectancy < 12 months, impossibility for follow-up, renal or hepatic failure, previous PTS or varicosis and recurrent thrombosis during follow up. Endpoint: PTS at 12 months. Explicative variables: clinical risk factors for DVT, D-dimer value, hypercoaguable state, anticoagulant therapy and compression stockings compliance. Multivariable analysis (logistic regression) was performed. RESULTS: One hundred and seventy two patients with DVT were evaluated for inclusion. Sixty nine were excluded and 87 patients completed follow-up. PTS appeared in 47 patients (54%). Compliance of compression stockings was adequate in 57% of patients and decreased 45% the risk for PTS (p = 0.01). No significant associations were observed between PTS and others variables. Multivariable analysis confirmed the protective effect of compression stockings (RR = 0.3; p < 0.01) and previous ipsilateral DVT appeared significatively associated with PTS development (RR = 8; p = 0.01) CONCLUSIONS: About 50% of patients with proximal DVT develop PTS within 1 year. Previous ipsilateral DVT is the strongest risk factor for PTS. Regular compression stocking use decreases the risk of PTS by 50%.

Duplex screening as a method of quality assurance of perioperative thromboembolism prophylaxis.

BACKGROUND: Improvements in thrombosis prophylaxis in both the operative and non-operative fields aim to reduce further the not inconsiderable residual risk of suffering a deep vein thrombosis or embolism. The goal of the study was to establish the part played in a quality assurance strategy by early diagnosis of a thrombosis and by knowledge of the hospital's internal patient-risk profile in order to counter the unpredictability of thromboembolic complications and make rational decisions about thromboembolism prophylaxis. METHODS: Duplex ultrasonography has been used routinely in trauma surgical patients in Krefeld Hospital since September 1991 as a screening method for diagnosing deep leg and pelvic vein thrombosis prior to mobilisation of the patients. 778 patients were investigated up to March 1997. In the period from September 1991 to September 1994, patients received standardised low-dose prophylaxis with unfractionated heparin (UFH). In October 1994, the prophylaxis regimen was modified by changing the anti-embolism stockings from bidirectional elastic stockings to transverse elastic graduated compression stockings (TED) and by adapting the dosage of the heparin prophylaxis to patient risk, with the use of low molecular weight heparin (LMWH) Certoparin (Mono-Embolex NM) since April 1995. All patients with a deep vein thrombosis were treated immediately with APTT-monitored full heparinisation and immobilisation. RESULTS: In the period from September 1991 to March 1997, an asymptomatic deep vein thrombosis of the lower limbs was diagnosed in 68 cases (8.7%) out of 778 trauma surgical patients by means of routine duplex ultrasound. Using a strategy of duplex screening and immediate anticoagulation/immobilisation, no clinically significant pulmonary emboli occurred in this period. At the same time, the antithrombotic efficacy of the prophylaxis could be improved and assessed objectively by means of duplex screening: with optimal compression stockings and consistent use of risk-adapted UFH prophylaxis, it was possible to reduce the residual thrombosis rate, which was 11.5% (95% CI 7.7-15.2%) with standard UFH prophylaxis, to 8.7 % (95% CI 4.5-12.9%) and ultimately, using the combination of optimal anti-embolism stockings and LMWH prophylaxis, to 6.0% (95% CI 3.0-8.9%) which was significant (p<0.05). The cost-effectiveness analysis resulted in a cost-relation per successfully treated patient of about 1:100 for the diagnosis of a deep vein thrombosis using duplex ultrasound and subsequent heparin treatment compared to the diagnosis and intensive care treatment of a massive pulmonary embolism. CONCLUSIONS: Duplex ultrasound screening for asymptomatic deep vein thrombosis thus proves to be a suitable instrument for internal hospital quality control in thrombosis prophylaxis. Its routine use can be recommended at least in high-risk patients, not only from the medicolegal aspect but also from the purely economic aspect.

Prophylaxis of deep venous thrombosis after acute abdominal operation.

Two hundred and forty-five patients who underwent acute extensive abdominal operations were randomized into three regimens to achieve optimal prophylaxis of postoperative thromboembolic complications. All of the patients were screened by the 125I-fibrinogen uptake test for seven days and if the phlebographic findings were positive. Of 81 patients receiving low dose heparin, 12 had thromboembolism. Of 79 receiving a combination of low dose heparin and graded compression stockings, two had thromboembolism, and of 85 receiving a combination of dextran and graded compression stockings, 13 had this complication. This difference is significant in favor of the second treatment (p = 0.013). It is concluded that the combination of low dose heparin and graded compression stockings is an effective way to prevent thromboembolism after acute abdominal operations.

Deep vein thrombosis after major reconstructive spinal surgery.

STUDY DESIGN: A prospective study was performed. OBJECTIVES: The goals of the study were to determine the incidence of deep vein thrombosis after major adult spinal surgery and the optimal mode of prophylaxis in this surgical population. SUMMARY OF BACKGROUND DATA: Few studies have evaluated deep vein thrombosis incidence and prophylaxis after major adult spinal surgery. Incidence rates have ranged from 0.9-14%. METHODS: Three hundred twenty-nine patients were evaluated. One hundred ten patients were randomized to 3 different deep vein thrombosis prophylaxis groups. These patients had duplex doppler scans between the fifth and seventh postoperative days. The remaining 219 patients formed a nonrandomized group and received either thrombosis embolic deterrent stockings alone or thrombosis embolic deterrent stockings and pneumatic compression boots for deep vein thrombosis prophylaxis. The type of deep vein thrombosis prophylaxis in this group was based on surgeon preference. All 329 patients were followed for clinical signs and symptoms of thromboembolic disease. Patients were followed clinically for a minimum of 1 year. RESULTS: All 110 prophylaxis study group patients were clinically asymptomatic and 109 duplex scans were normal. One scan was indeterminate and a follow-up venogram was negative. Two patients in the coumadin group (5.7%) experienced excessive blood loss. One of the 219 patients from the nonrandomized group developed a clinically detectable proximal deep vein thrombosis which was confirmed by duplex ultra-sonography. The overall clinical incidence of deep vein thrombosis was 0.3% (1 in 329 patients). CONCLUSIONS: This low 0.3% rate is in agreement with recent studies that focus on thromboembolic disease. Given the low incidence, routine screening for asymptomatic thrombi appears unwarranted. In addition, mechanical prophylaxis with graduated compression stockings and pneumatic compression boots is preferable to anticoagulation therapy.

Fifteen-year results of ambulatory compression therapy for chronic venous ulcers.

A nonoperative approach to venous stasis ulceration of the lower extremity, consisting of initial bedrest, ulcer cleansing, dressing changes, and ambulatory elastic compression stocking therapy, has been maintained for over 15 years. All patients had class III, severe chronic venous insufficiency. One hundred five of 113 patients (93%) experienced complete ulcer healing in a mean of 5.3 months. One hundred two patients were compliant with elastic compression stockings, and 11 patients were noncompliant. Complete ulcer healing occurred in 99 of 102 patients (97%) who were compliant versus six of 11 patients (55%) who were noncompliant (p less than 0.0001). The influence of noncompliance, previous venous ulceration, previous venous surgery, previous known deep venous thrombosis, peripheral arterial insufficiency (ankle brachial systolic blood pressure index less than or equal to 0.60), pretreatment ulcer duration, ulcer size, age, sex, diabetes, smoking, and photoplethysmography venous refill time on ulcer healing was determined by logistic regression analysis. Only noncompliance with elastic compression stockings (p less than 0.0001) and a pretreatment ulcer duration of more than 9 months (p = 0.02) significantly decreased initial ulcer healing. Posthealing follow-up was available in 73 patients for a mean of 30 months. Fifty-eight patients (79%) continued to be compliant with stockings; 15 patients were noncompliant. Total ulcer recurrence in patients who were compliant was 16%. Five-year lifetable recurrence was 29%. All patients who were noncompliant had recurrent ulceration by 36 months. Previous ulceration, previous venous surgery, and peripheral arterial insufficiency had no effect on ulcer recurrence (p greater than 0.05).

Compression therapy for treating stage I and II (Widmer) post-thrombotic syndrome.

BACKGROUND: Post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis characterised by chronic complaints, swelling, and skin changes in the affected limb. One in every three patients with deep vein thrombosis develops post-thrombotic complications within five years. OBJECTIVES: To assess the effectiveness of compression therapy in patients with stage I and II post-thrombotic syndrome according to the classification of Widmer. Interventions of interest included elastic compression stockings and mechanical devices, compared with no intervention and with each other. SEARCH STRATEGY: The reviewers searched the Cochrane Peripheral Vascular Diseases Specialised Trials Register (last searched April 2003), and the Cochrane Central Register of Controlled Trials (CENTRAL) (last searched Issue 1, 2003). In addition, journals, conference proceedings and bibliographies were hand searched. Personal contact with other investigators involved in the clinical area was sought to get information about missed or unpublished studies. SELECTION CRITERIA: Trials that evaluated compression therapy for stage I and II (Widmer) post-thrombotic syndrome. Primary outcomes were leg ulceration, or deterioration of post-thrombotic syndrome. There were no restrictions on date or language. One reviewer (DNK) assessed titles and abstracts for relevance. This was verified independently by a second reviewer (MWCS). DATA COLLECTION AND ANALYSIS: Details of eligible studies were extracted and summarised using data extraction sheets. Data extraction was undertaken by one reviewer (DNK) and verified by a second reviewer (MHP). MAIN RESULTS: Only two trials were identified that addressed physical treatment of post-thrombotic syndrome. Both trials were initiated by the same group of investigators. A cross-over study lasting two months compared low and high pressure with intermittent compression units for severe post-thrombotic syndrome. This showed a beneficial effect of higher pressures. The second study, in patients with mild to moderate post-thrombotic symptoms, showed no effect of elastic compression stockings (30-40 mm Hg at the ankle region) when compared to 'placebo' stockings that were one to two sizes too large. REVIEWER'S CONCLUSIONS: There is some evidence of a beneficial effect of intermittent pneumatic compression units, but the study was too small and of too short a duration to draw strong conclusions. Further research is needed in order to assess whether intermittent pneumatic compression units give long term reduction and relief of the symptoms caused by post-thrombotic syndrome, and prevent deterioration and leg ulceration. The use of elastic compression stockings to treat post-thrombotic syndrome cannot be supported on the basis of the currently available data.

Does supervised exercise after deep venous thrombosis improve recanalization of occluded vein segments? A randomized study.

OBJECTIVES: The aim of the present study was to evaluate weather early supervised exercise improves recanalization of acute deep vein thrombosis (DVT) and reduces symptoms. PATIENTS AND METHODS: From September 2001 to March 2004, of 381 patients, 72 eligible patients were included and with a mean age 54 +/- 14 years, 39 (52%) men with deep vein thrombosis (DVT) proven with phlebography were randomized to: an exercise group (n = 36) receiving routine anticoagulation, class II compression stockings and additionally supervised exercise and a control group (n = 36) receiving the same therapy but no exercise. Patients were followed-up during six months. Phlebography was scored initially and at six-months. RESULTS: There were at inclusion no differences between the two groups regarding age, body weight, body mass index (BMI), calf circumference of the affected leg, and overall quality of life estimated by visual analog scale (VAS)-scale. In both groups there were significant reductions regarding calf circumference in the affected leg compared to the inclusion time, both at one-month (P = 0.0012) and six month (P = 0.0002) follow-up. The degree of recanalization of the affected venous segments was high and did not differ between groups. There were no recurrent DVT or pulmonary emboli or other treatment complications in any individual during the six-month follow-up period. CONCLUSIONS: Early exercise did not acutely exacerbate the risk of complications in patients with DVT. No benefits of early exercise were seen regarding the degree of recanalization of the thrombi, or faster resolution of pain or swelling. Nevertheless, our study shows that early exercise/ambulation is safe in combination with anticoagulation and compression stockings for the majority of patients with DVT.

Thigh length versus knee length stockings in the prevention of deep vein thrombosis.

Above-knee graduated compression stockings are effective in preventing postoperative deep vein thrombosis, but are more expensive and less acceptable than below-knee stockings. One hundred and fourteen patients undergoing major abdominal surgery were randomly allocated to wear above-knee or below-knee graduated compression stockings. Deep vein thromboses were diagnosed by isotope uptake in three of 56 patients (5.4 per cent) in the above-knee group and one of 58 patients (1.7 per cent) in the below-knee group. These differences are not statistically significant. Results suggest that below-knee stockings are as effective as above-knee in the prevention of postoperative deep vein thrombosis.

Air-plethysmography and the effect of elastic compression on venous hemodynamics of the leg.

Leg volume changes during exercise have been measured in absolute units (milliliters) by means of a new method of air-plethysmography. Venous volume (VV), venous filling time, and venous filling index on standing from the recumbent position, ejected volume (EV) and ejection fraction (EF = EV x 100/VV) with one tiptoe movement, and residual volume (RV) and residual volume fraction (RVF = RV x 100/VV) after 10 tiptoe movements were measured in normal limbs, limbs with superficial venous incompetence, and limbs with deep venous disease. The same measurements were repeated with a graduated medium compression stocking in limbs with SVI and graduated high compression stockings in limbs with DVD. Ambulatory venous pressure was measured at the same time, with a needle in a vein in the foot. The results indicate that this method of air-plethysmography is not only of diagnostic value but offers a new and unique technique to assess and study the hemodynamic effects of different forms of elastic compression. The lower ambulatory venous pressure, produced by the elastic compression, was the result of a reduction in reflux and an improvement in the calf muscle ejecting ability during rhythmic exercise.

Long-term outcomes after deep vein thrombosis: postphlebitic syndrome and quality of life.

In this review, we critically assess the literature on the incidence of postphlebitic syndrome, risk factors for its occurrence, available therapeutic options, and its effects on quality of life. As well, we describe available tools to measure postphlebitic syndrome. Recent prospective studies indicate that postphlebitic syndrome, a chronic, potentially disabling condition characterized by leg swelling, pain, venous ectasia, and skin induration, is established by 1 year after deep vein thrombosis (DVT) in 17% to 50% of patients. The only prospectively identified risk factor for its occurrence is recurrent ipsilateral DVT. In the sole randomized study available, daily use of elastic compression stockings after proximal DVT reduced the incidence of postphlebitic syndrome by 50%. Treatment options for established postphlebitic syndrome are limited, but include compression stockings and intermittent compressive therapy with an extremity pump for severe cases. To date, quality of life after DVT has received little attention in the literature. The recent development of the VEINES-QOL questionnaire, a validated venous-disease-specific measure of quality of life, should encourage researchers to include quality of life as a routine outcome measure after DVT. There is no criterion standard for the diagnosis of postphlebitic syndrome, but a validated clinical scoring system does exist. More research on postphlebitic syndrome is needed to enable us to provide DVT patients with comprehensive, evidence-based information regarding their long-term prognosis, to help quantify the prevalence and health care burden of postphlebitic syndrome, and by identifying predictors of poor outcome, to develop new preventive strategies in patients at risk of developing this condition.

Screening for proximal deep vein thrombosis after acute ischemic stroke: a prospective study using clinical factors and plasma D-dimers.

Deep vein thrombosis (DVT) remains common in patients with acute ischemic stroke (AIS) receiving aspirin and graded compression stockings (considered standard thromboprophylaxis in the UK), most events occurring in patients with Barthel indices (BI) of <9 ('severe stroke') around the time of admission. In the absence of data indicating improved clinical outcomes with use of low-dose anticoagulant thromboprophylaxis, we evaluated the hypothesis that plasma D-dimers (D-d) might be a valuable initial screening test for proximal DVT (PDVT), facilitating selective use of imaging. One hundred and two unselected AIS-patients receiving aspirin/graded compression stockings thromboprophylaxis were screened for DVT using magnetic resonance direct thrombus imaging, a highly accurate non-invasive technique which directly visualizes thrombus. D-d (VIDAS and IL test D-d assays) were measured on recruitment and at weekly intervals. Median D-d were significantly higher throughout the study in patients with severe stroke who developed PDVT vs. those with severe stroke not developing PDVT, differences being most marked around day 9. Depending on the discriminatory threshold used, a single D-d measurement at this time in patients with severe-AIS allowed identification of a subgroup with ~50% prevalence of PDVT. Sensitivity of these strategies for PDVT was 67-83%, at a cost of imaging 22-30% of the entire cohort of patients. A single measurement of BI around the time of admission and D-d level at day 9 in AIS-patients receiving aspirin/graded compression stockings thromboprophylaxis allows identification of a subgroup containing a substantial proportion of all PDVTs who could be selectively imaged.
