[Indications for ready-made or custom-made compression stockings].

The author studies ready-made stockings and the techniques of classification by category and by pressure. He examines at the same time, custom-made circular or linear knit stockings. His comments lead to the conclusion that the basic problem is the effectiveness of the stocking, especially in patients whose case is somewhat unusual. Pressure must remain consistently even, and there may be problems in pressure linked to the flexibility of the tissues.

[Prevention of deep venous thrombosis (TVP) and pulmonary embolism. Comparison of heparin (3 x 5000 IU/day), heparin (2 x 5000 IU/day) + 0.5 mg dihydroergot, and physiotherapy (intermittent compression stockings + physical exercise). Value of Doppler diagnosis in systematic detection of TVP compared with phlebography and scanning of the legs using labelled fibrinogen].

We compared the protective value of the above treatments in 227 randomised patients. Investigations in each patient included pulmonary scanning before and after operation, repeated postoperative Doppler and radioactive limb scanning completed by phlebography to confirm positive results. The heparin DHE group and the "physiotherapic" group each totalized 76 patients and the heparin group 75. These comparable groups show that HDHE and heparin prophylaxis are identical; but physiotherapy is perhaps better. Compared with phlebography leg scanning sensitivity is 95%, whilst it's specificity is 99%. Doppler sensitivity is only of 21%, whilst it's specificity is 95%. In conclusion, "physiotherapic" prophylaxis, including Flowtron, is as effective as heparin alone. Doses of heparin may be reduced, without loss of effect, if supplemented by a veinoconstrictive agent as DHE. The low Doppler sensitivity contraindicates its use in asymptomatic DVT detection.

Prevention of deep-vein thrombosis after total hip and knee replacement. Low-molecular-weight heparin in combination with intermittent pneumatic compression.

After total hip (THR) or knee replacement (TKR), there is still an appreciable risk of developing deep-vein thrombosis despite prophylaxis with low-molecular-weight heparin (LMWH). In a prospective, randomised study we examined the efficacy of LMWH in combination with intermittent pneumatic compression in patients undergoing primary unilateral THR or TKR. We administered 40 mg of enoxaparin daily to 131 patients combined with either the use of intermittent pneumatic compression or the wearing of graduated compression stockings. Compression ultrasonography showed no evidence of thrombosis after LMWH and intermittent pneumatic compression. In the group with LMWH and compression stockings the prevalence of thrombosis was 28.6% (40% after TKR, 14% after THR). This difference was significant (p < 0.0001). In the early post-operative phase after THR and TKR, combined prophylaxis with LMWH and intermittent pneumatic compression is more effective than LMWH used with graduated compression stockings.

Current concepts in the management of varicose veins.

Varicose veins are a very common problem, affecting women more than men. The major concern is usually the unsightly appearance of the veins. Various options to deal with this problem are discussed-- compression stockings, compression sclerotherapy and surgery. For good results and patient satisfaction, the cause and natural history of varicose veins must be understood. Depending on the type of varicose vein, different modalities of treatment are required and may need to be combined. "Cosmetic" varicosities can usually be managed conservatively with compression stockings. Sclerotherapy is best used for dilated superficial or residual varicose veins, recurrent varicosities or leg perforators. Operation should be reserved for very large varicose veins or an incompetent long or short saphenous vein. A sound understanding of the problems and discussion of anticipated results with the patient will prevent unrealistic expectations.

Immediate mobilisation in acute vein thrombosis reduces post-thrombotic syndrome.

AIM: To investigate the effect of compression and immediate ambulation in the acute stage of deep vein thrombosis (DVT) on the development of postthrombotic syndrome (PTS). METHODS DESIGN: follow-up study of patients who previously have been enrolled in a randomized controlled trial. SETTING: outpatient department of a municipial hospital. SUBJECTS AND INTERVENTIONS: a follow-up was performed 2 years after 53 patients with acute proximal DVT had been enrolled into a randomized controlled trial, comparing bed rest and no compression (n=17), Unna boot bandages plus walking (n=18) and compression stockings plus walking (n=18). Telephone interviews could be conducted with 11 patients, 37 patients could be reinvestigated by independent observers (11 from the bed-rest group, 13 from the bandage group and 13 from the stocking group). Compression stockings up to the time of the follow-up were worn by 8/11 (73%) of the bed-rest patients and by 13/26 (50%) of the mobile patients. MAIN OUTCOME MEASURES: clinical and venous duplex investigation, pain assessment using visual analogue scale and Lowenberg test, leg circumference, clinical ''PTS-score'' combining 5 subjective symptoms with 6 objective signs (Villalta-Prandoni-scale). RESULTS: Duplex investigation of the deep veins and pain assessment by visual analogue scale showed no significant differences between the groups. Nine out of 11 patients after bed rest, but only 16/26 in the mobile groups showed a larger calf circumference on the diseased leg (n.s.). Judged by the Villalta-Prandoni-scale a significantly better outcome could be found in the mobile group (mean score 5.1) than in the bed-rest group (mean score 8.2), (p<0.01). (''Mild PTS'' = score 5-14, ''severe PTS'' score = or > 15). Eighteen out of 26 mobile patients, but only 2/11 bed-rest patients had a score = or < 5 (''no PTS''). CONCLUSIONS: Immediate mobilisation with compression in the acute stage of DVT reduces the incidence and the severity of PTS.

Effect of different compression therapies on the reflux in deep veins with a post-thrombotic syndrome.

BACKGROUND: Reflux in deep veins is an important pathophysiological factor of post-thrombotic syndrome which can be demonstrated by colour-coded duplexsonography. This study investigates the effect of different compression therapies on the reflux velocity in deep veins in patients with a post-thrombotic syndrome. PATIENTS AND METHODS: Sixty patients with a post-thrombotic syndrome-confirmed by phlebography, in the deep veins of the calf and the thigh were investigated in two groups: In group A, 30 patients (mean age 58 +/- 10 years) received compression stockings (calf compression class II and III, thigh compression class II) and in group B 30 patients (mean age 58 +/- 14 years) received a Sigg short traction bandage of the calf. The velocity at the time of the greatest reflux in the popliteal vein was determined as reflux parameter with the colour-coded duplex sonography using a cuff applied at the calf. All patients stood upright and were measured with and without different kinds of compression therapies. The reflux velocities were graded as low, moderate and high. RESULTS: A significant decrease of the reflux velocity by about more than 45% with compression therapy was found in both groups. The decrease of the refluxes in group A (mean 47.9%) did not differ significantly from the decrease of refluxes in group B (mean 55.8%). The greatest decrease of the reflux velocity under compression therapy was found in high-grade refluxes in both groups. CONCLUSION: A significant decrease of the reflux velocity in post-thrombotic syndrome can be readily demonstrated with different kinds of compression stockings as well as with bandages by means of colour-coded duplex sonography.

[Medical compression therapy].

In order to evaluate the correlation between the pressure exerted by compression stockings and a resulting improvement in venous hemodynamics, we carried out an open, randomized, prospective study on 22 patients (11 women and 11 men with an average age of 55.1 [10.3]) with chronic venous insufficiency (CVI) in the clinical stages C1-4, Ep, AS, Ap, PR. Dynamic strain gauge plethysmography was used to measure the acute effect on venous hemodynamics of 9 different compression stockings in compression class 2 (A-D). At the same time when venous function parameters were monitored, we also measured the pressure exerted by the compression stockings during rest and exercise. With all compression stockings the average resting pressure fulfilled in reclined patients the specifications for compression class 2 (25-35 mmHg at the ankle, CEN). The compression stockings lengthened venous refill time t0 in a statistically significant degree. The improvement in venous function was correlated with the ratios of maximal working pressure to resting pressure while standing (r = 0.97, p < 0.001). Compression stockings belonging to the same compression class vary in their acute effect on venous hemodynamics. The efficiency of the different therapeutic compression stockings was largely dependent on the amount of fabric stretch, which can be characterized in vivo with the ratio of maximum exerted pressure during movement to that while standing still. A knowledge of the hemodynamic effectivity of the various compression stockings allows the optimal stocking selection for each patient and his individual clinical situation.
