An exploration of current leg ulcer management practices in an Irish community setting.

OBJECTIVE: To establish the prevalence of leg ulceration in the Irish Health Service Executive (HSE) mid-western region and to determine the level of assessment and treatment patients have been receiving in the local community. METHOD: Before the introduction of a Doppler training programme, all public health and community health nurses working in the Irish HSE mid-western area were requested to complete an audit form on each patient being treated for leg ulceration during a predefined one-week period. This form recorded details on patient demographics, ulcer aetiology, assessment and treatment. Out of 97 nurses, 96 responded to this audit, giving a response rate of 98.9%. RESULTS: A total of 429 patients with 449 leg ulcers were identified. Mean age was 75.5 years (standard deviation 10.7). Overall prevalence was 0.12%, which increased to 1.2% in those aged 70 years and over. Women were almost twice as likely as men to be affected (ratio of 1.8:1). The main causes of ulceration were reported as venous incompetence accounting for 63.3% (284/449) and arterial insufficiency accounting for 8% (36/449) of all ulcers. Only 59.9% (269/449) of all ulcerated limbs had ABPI measurements performed. Of those reported as venous in origin, 71.8% (204/284) had ABPI measurements recorded. Evidence-based care was generally apparent in this group, with 47.5% (97/204) receiving high compression and 18.1% (37/204) receiving reduced compression. However, in venous leg ulcers where ABPIs were not recorded (n=80) care appeared haphazard and inappropriate. CONCLUSION: Our study has identified the benefit of ABPI Doppler assessment.This assessment could be done in local health centres by trained nurses who could provide more appropriate and timely care to patients, thereby improving outcomes and relieving pressure on acute hospital clinics.

Skin grafting for venous leg ulcers.

BACKGROUND: Venous leg ulceration is a common, recurring, disabling condition affecting up to 1% of adults. Treatment is aimed at healing with simple dressings and compression bandages / stockings. Unfortunately in some cases this treatment is unsuccessful with ulcers remaining open for months or years. In order to stimulate healing, some clinicians use skin grafts. These skin grafts may be taken from the patients own uninjured skin (e.g. thigh), may be grown from the patient's skin cells into a dressing, (both known as autografts) or applied as a sheet of bioengineered skin grown from a donor cells (known as an allograft). Preserved skin from other animals, e.g. pigs, have also been used and these are known as xerografts. OBJECTIVES: To assess the effectiveness of skin grafts in the treatment of venous leg ulcers. SEARCH STRATEGY: We searched the Cochrane Wounds Groups specialised register (date of search October 1999), and reference lists of relevant articles. We hand searched relevant journals and conference proceedings, and contacted experts in the field. SELECTION CRITERIA: Randomised controlled trials evaluating skin grafts in the treatment of venous leg ulcers. There was no restriction on articles based on language or publication status. DATA COLLECTION AND ANALYSIS: Data extraction and assessment of study quality was undertaken by two reviewers independently. Trials with similar patients, comparisons, and outcomes were pooled. MAIN RESULTS: Seven RCTs of skin grafts for venous leg ulcers were identified. In 6 trials patients also received compression bandaging. Two trials (98 patients) evaluated split thickness autografts, three trials (92 patients) evaluated cultured keratinocyte allografts, one compared tissue engineered skin (artificial skin) with a dressing (309 patients) and one compared it with a split thickness skin graft (7 patients, 13 ulcers). The trials comparing artificial skin with a dressing reported a significantly higher proportion of ulcers healing with artificial skin. There was insufficient evidence from the remaining trials to determine whether other types of skin grafting increased the healing of venous ulcers. REVIEWER'S CONCLUSIONS: There is limited evidence that artificial skin used in conjunction with compression bandaging, increases the chance of healing a venous ulcer compared to compression alone. Further research is needed to assess whether other forms of skin grafts increase ulcer healing.

Living with venous leg ulceration: issues concerning adherence.

Compression therapy is advocated for the treatment of chronic venous leg ulceration and the proportion of patients whose ulcers heal appears to be directly related to adherence (Moffatt, 2004). The aim of this study was to examine patients' understanding of adherence, in terms of their own experiences of compression bandage systems. Following full ethical approval, a purposeful sample of 6 participants was recruited to take part in a focus group. Free-flowing conversation was encouraged so that the participants could discuss issues that were important to them, although a series of prompts were available to stimulate the conversation when necessary. Four major themes were identified using a phenomenological approach: frustration with the healthcare system leading to a feeling of complacency with primary healthcare teams; functional limitations leading to adaptation of everyday life situations (e.g. bathing and coping with pain); emotional reactions affecting well-being and body image, and perception of others; and avoidance of transport, shopping and holidays.

Excision and meshed skin grafting for leg ulcers resistant to compression therapy.

BACKGROUND: The aim of this study was to determine the success of excision and meshed skin grafting for chronic leg ulcers. The effects of different ulcer aetiology and ulcer size on outcome were also assessed. METHODS: All patients who had excision and mesh grafting for chronic leg ulceration between January 1996 and December 2004 at St Thomas' Hospital were reviewed. Recurrence was classified as any breakdown of the ulcer during follow-up. RESULTS: Sixty-two patients with 100 chronic leg ulcers underwent operation. Seventy-two of the ulcers were venous and the median ulcer size was 36 (range 1.5-192) cm2. Only three patients left the hospital with their ulcers unhealed, but ulcers had recurred in 28 (28 per cent) by 2 months. A further 17 ulcers recurred later, with just over half (55 per cent) remaining healed by 5 years. There was no difference between the recurrence rates of venous ulcers and ulcers of other aetiologies (P=0.980), or large (more than 10 cm2) and small ulcers (P=0.686). CONCLUSION: Wide local excision and meshed skin grafting benefitted over half of these patients with refractory leg ulcers. Recurrence was most likely to occur in the first 2 months and, provided that ulcers were healed at this time, there was a low rate of further breakdown.

The Ulcerated Leg Severity Assessment score for prediction of venous leg ulcer healing.

BACKGROUND: The aim of the study was to create a reliable scoring system for the prediction of venous ulcer healing in patients treated with compression. METHODS: A prospective baseline study to identify risk factors for venous ulcer healing was undertaken between March 1999 and August 2001. All patients were treated with multilayer compression. A number of variables were related to 24-week healing rates. A Cox regression model was used to identify risk factors that predicted ulcer healing, from which a scoring system was developed and validated prospectively between February 2004 and March 2005. RESULTS: In the baseline study of 229 patients, patient age, ulcer chronicity and venous refill time (VRT) of 20 s or less were identified as risk factors. Using these factors and hazard ratios from the Cox regression analysis, the following formula was devised: Ulcerated Leg Severity Assessment (ULSA) score=age+chronicity-50 (when VRT is greater than 20 s). Patients with an ULSA score of 50 or less had higher 24-week ulcer healing rates than those with higher scores in both the baseline study (P<0.001, log rank test) and the validation study performed in 86 patients (P=0.007, log rank test). CONCLUSION: The ULSA score may help to identify patients with venous ulcers unlikely to respond to conventional treatment who could be offered alternative therapy.

A factorial, randomized trial of pentoxifylline or placebo, four-layer or single-layer compression, and knitted viscose or hydrocolloid dressings for venous ulcers.

OBJECTIVES: We evaluated the effectiveness of pentoxifylline, knitted viscose or hydrocolloid dressings, and single-layer or four-layer bandaging for venous ulceration. METHOD: A factorial randomized controlled trial with 24-week follow-up was conducted in leg ulcer clinics in Scotland with blinded allocation to pentoxifylline (1200 mg) or placebo, knitted viscose or hydrocolloid dressings, and single-layer or four-layer bandages. The study enrolled 245 adults with venous ulcers. The main outcome measure was time to complete healing. Secondary outcomes included proportions healed, withdrawals, and adverse events. Analysis was by intention to treat. RESULTS: There was no evidence of interaction between the drug, bandages, and dressings. Pentoxifylline was associated with nonsignificant increased ulcer healing (62% vs 53%; P = .21). Four-layer bandages were associated with significantly higher healing rates (67% vs 49%; P = .009). There was no difference in healing between knitted viscose and hydrocolloid dressings (58% and 57%; P = .88). Cox regression models increased the significance of the pentoxifylline effect (relative risk of healing, 1.4; 95% confidence interval, 1.0 to 2.0). CONCLUSIONS: Pentoxifylline increased the proportion healing compared with placebo to the same extent as shown in recent systematic reviews, although this finding was only statistically significant when a secondary adjusted analysis was conducted. Four-layer bandaging produced higher healing rates than single-layer bandaging. There was no difference in time to healing between knitted viscose and hydrocolloid dressings.

Effects of compression tights on calf muscle oxygenation and venous pooling during quiet resting in supine and standing positions.

AIM: We applied near-infrared spectroscopy (NIRS) to evaluate in resting conditions the effects of compression tights (CT) on calf muscle oxygenation and venous pooling compared with Lycra(R) elastic tights (ET) and shorts (no compression) according to the body posture (supine vs standing). METHODS: Twelve sportsmen regularly involved in endurance training volunteered to this study. Their average age, height and weight (+/-SD) were 26.5+/-2.6 years, 177+/-6 cm and 70.1+/-4 kg, respectively. Tissue oxygenation index (TOI), deoxyhemoglobin (HHb), and blood pooling (Hbtot) of the right gastrocnemius medialis were continuously monitored at 2 Hz using a NIRS device (NIRO-300, Hamamatsu Photonics, Japan). A home made transducer was used to measure applied pressure at the interface between skin and clothing over the calf area. Subjects were asked to realize a supine-standing protocol (5 min for each position) by wearing CT, ET or shorts in a counterbalanced order on the same day. RESULTS: HHb and Hbtot concentration changes were significantly lower whereas TOI was significantly higher by wearing CT compared with shorts and ET (P<0.001) as did supine compared to upright postures. The mean pressures applied over the calf were 5.6 and 23.2 mmHg during supine and 5 and 24.1 mmHg during standing for ET and CT, respectively. Pressures were significantly different among clothing according to the following rank order: CT>ET>shorts (P<0.001). CONCLUSIONS: CT compared to ET have positive effects on calf muscle oxygenation and venous pooling in quiet resting positions.

Compliance and satisfaction with foot compression devices: an orthopaedic perspective.

INTRODUCTION: Although mechanical methods of thromboembolic prophylaxis have proven efficacy, relatively little is known about levels of patient compliance in the usage of these devices. Based on anecdotal evidence, we hypothesised that levels of compliance are sometimes insufficient to provide adequate thromboprophylaxis in the clinical setting. We prospectively analysed the use of foot pumps in 30 orthopaedic patients undergoing lower limb arthroplasty in order to assess levels of both patient compliance and satisfaction. MATERIALS AND METHODS: The study was carried out over a 5-month period. Levels of compliance were measured by using a system of random "spot checks". Each patient completed a questionnaire before discharge. Parameters investigated included comfort levels while using the device and identification of factors about the device which the patients disliked. RESULTS: Three hundred and ninety-one measurements were made. The utilisation of the device was found to be effective in 40.2% of measurements. We detected an overall progressive decline in the level of compliance as post-operative time increased [P < 0.001, Chi-square (chi(2)) test]. The average level of patient "comfort" was 7.1 on a visual analogue scale of 0-10. Sleep disturbance was reported by 57% of patients, while 43% complained of "heat intolerance". We have also shown that compliance is significantly reduced in those who complained of "sleep disturbance" while using the foot pumps (t-test, P < 0.05). CONCLUSIONS: These findings suggest that satisfactory levels of compliance can be difficult to achieve in the clinical setting despite the proven efficacy in clinical trials of this device. Greater emphasis on patient education may help improve compliance. Unless compliance can be strictly enforced, it appears advisable to only use foot pumps in combination with other forms of pharmacological prophylaxis.

Thromboembolic prophylaxis as a risk factor for postoperative complications after breast cancer surgery.

Hematoma and bruising (sugillation) are frequent problems after operations for primary breast cancer. In the present study we evaluated the influence of various methods of perioperative thromboembolic prophylaxis on the postoperative incidence of hematoma and suggilation. From June 1994 through August 1996, a series of 425 patients consecutively operated on for primary breast cancer were included. Thromboembolic prophylaxis was low-molecular-weight heparin (LMWH) in 310 patients and thigh-long graded compression (TED) stockings in 102 patients. Postoperative complications including deep vein thrombosis, pulmonary embolism, wound hematoma, and sugillation were recorded, and 17 variables with a potential influence on complications were analyzed by logistic regression analysis. Heparin prophylaxis compared to prophylaxis with TED stockings was significantly and independently associated with postoperative hematoma [odds ratio (OR) 3, 13; 95% confidence interval (CI) 1.38-7.13] or sugillation (OR 3.34; 95% CI 1.93-5.78). No clinically overt thromboembolic complications were diagnosed. After operations for breast cancer we found that LMWH was significantly associated with postoperative hematoma and sugillation compared to TED stockings for perioperative thromboembolic prophylaxis.

[Surgical reduction of fat surplus leading to pulmonary embolism].

Surgical reduction of fat surplus is usually performed on healthy individuals and is reported as a safe procedure as it is not associated with a lethal outcome. Due to the anticipation of peri- and postoperative bleeding as a result of the large wound area, which may have a negative influence on the cosmetic result, patients often receive no or only inadequate anticoagulation. We report three cases in which surgical reduction of fat surplus led to sudden collapse and cardiac arrest. In all of our patients, fatal pulmonary embolism was the cause of cardiac arrest. These patients received only inadequate or no anticoagulation. Early postoperative mobilization, elastic stockings and compressive wound-dressing did not prevent pulmonary embolism. In addition to early postoperative mobilization of the patient and even though there is a risk of perioperative bleeding complications, the use of anticoagulation is highly recommended in surgical procedures like abdominoplasty or dermolipectomy. If sudden dyspnea, chest pain, collapse or cardiac arrest occurs after surgical interventions like these, pulmonary embolism should be considered and further diagnostic steps should be initiated.

[Surgical treatment of arteriovenous malformations].

MAV surgery remains still today one of most difficult in the surgery of vascular malformations. Embolisation the most selective possible follow-up of a surgical removal carrying the totality of the nidus is the only effective treatment. Usually, MAV of small size, quiescent, should not be operated, the surgery being reserved for the evolutionary or complicated forms. This surgical procedure must allow the complete eradication of the lesion without which the cure is not possible. The incomplete removal causes repetition, sometimes aggravation with, sometimes, life threatening problems.

[Medical and surgical treatment of venous malformations].

Treatment of venous malformations (VM) is difficult as these lesions are ill defined and can infiltrate tissues. Moreover, no specific treatment related to their etiopathogenesis exists. Currently, VM can be treated conservatively or medically and, more aggressively with either sclerotherapy, or surgical resection. A multidisciplinary approach is needed to obtain the best result with minimal complications. Surgical resection, complete or partial, plays an important role in the treatment of symptomatic VM. In case of extensive VM, all techniques of plastic surgery are indicated.

Attitudes to the use of prophylaxis for thrombo-embolism in neurosurgical patients.

Neurosurgical patients are at significant risk of thromboembolic complications. A survey of 58 consultant neurosurgeons in United Kingdom confirmed that 84.5% regularly used some form of prophylaxis. For all forms of neurosurgery, the most preferred method of prophylaxis was mechanical (graduated compression stockings-TEDS and intra-operative pneumatic calf compressors-IPC) or in the post-operative period a combination of mechanical methods and low molecular weight heparin (LMWH). LMWH was rarely administered in the perioperative period. The majority of neurosurgeons believed that TEDS and LMWH reduced post-operative DVT (79% and 90%, respectively) and PE (43% and 67%), but 29% associated LMWH with bleeding complications. A review of current literature revealed that TEDS, IPC, and LMWH are effective in reducing the incidence of DVT, but the evidence over the safety of heparin is inconclusive in neurosurgical patients. There is still room for improvement as a minority of neurosurgeons continue to ignore the importance of prophylaxis against thrombo-embolism in neurosurgery.

[Perioperative antithrombotic prophylaxis in varicose vein surgery].

Antithrombotic regimens to prevent venous thromboembolism are standard in the treatment of in-and outpatients with thrombotic risk factors. A classification of the level of risk is made depending on the age, kind of operation, existing hereditary or acquired thrombophilic diatheses and concomitant disease. The antithrombotic prophylaxis is performed in accordance with the classification of risk level in low, moderate, high and highest risk levels. Varicose disease is a thrombotic risk factor. Varicose vein surgery may be classified as thrombogenic. Patients with varicose vein surgery and without other clinical risk factors are low-risk patients. In case of other acquired or hereditary risk factors antithrombotic prophylaxis in varicose vein surgery with low molecular weight heparin should be used. Compression elastic stockings are obligatory.
