Intermittent sequential pneumatic compression of the legs and thromboembolism-deterrent stockings in the prevention of postoperative deep venous thrombosis.

One hundred fifty patients over the age of 30 who had undergone major abdominal operations were stratified according to the risk of deep venous thrombosis and randomized into three groups to receive different prophylactic regimens: group A, electrical calf stimulation; group B, low-dose subcutaneous heparin; group C, intermittent sequential compression and thromboembolism-deterrent (TED) stockings. All the patients were scanned with the 125I-fibrinogen test for the whole stay in hospital. The incidence of 125I-fibrinogen detected deep venous thrombi was 18% in group A, 9% in group B, and 4% in group C. The results indicate that the regimen of intermittent sequential compression and TED stockings is as effective as low-dose subcutaneous heparin. Electrical calf stimulation is less effective.

Superficial thrombophlebitis of the legs: a randomized, controlled, follow-up study.

The aim of the present study was to evaluate the effects of different treatment plans (compression only, early surgery, low-dose subcutaneous heparin [LDSH], low-molecular-weight heparin [LMWH], and oral anticoagulant [OC] treatment) in the management of superficial thrombophlebitis (STP), by considering efficacy and costs in a 6-month, randomized, follow-up trial. Patients with STP, with large varicose veins without any suspected/documented systemic disorder, were included. Criteria for inclusion were as follows: presence of varicose veins; venous incompetence (by duplex); a tender, indurated cord along a superficial vein; and redness and heat in the affected area. All patients were ambulatory. Exclusion criteria were obesity, cardiovascular or neoplastic diseases, bone/joint disease, problems requiring immobilization, and age > 70 years. Patients with superficial thrombophlebitis without varicose veins and patients under treatment with drugs at referral were also excluded. Color duplex (CD) was used to detect concomitant deep vein thrombosis (DVT) and to evaluate the extension or reduction of STP at 3 and 6 months. Venography was not used. Of 562 patients included, 3.5% had had a recent DVT in the same limb affected by SVT and 2.1% in the contralateral limb. In six patients DVT was present in both limbs. These patients were treated with anticoagulants and excluded from the follow-up. After 3 and 6 months the incidence of STP extension was higher in the elastic compression and in the saphenous ligation groups (p < 0.05). There was no significant difference in DVT incidence at 3 months among the treatment groups. Stripping of the affected veins was associated with the lowest incidence of thrombus extension. The cost for compression alone was the lowest and the cost including LMWH was the highest. The average cost was 1,383 US$. However the highest social cost (lost working days, inactivity) was observed in subjects treated only with stockings.

Foam-sclerotherapy, surgery, sclerotherapy, and combined treatment for varicose veins: a 10-year, prospective, randomized, controlled, trial (VEDICO trial).

The study compared, by a prospective, randomized method, 6 treatment options: A: Sclerotherapy; B: High-dose sclerotherapy; C: Multiple ligations; D: Stab avulsion; E: Foam-sclerotherapy; F: Surgery (ligation) followed by sclerotherapy. Results were analyzed 10 years after inclusion and initial treatment. Endpoints of the study were variations in ambulatory venous pressure (AVP), refilling time (RT), presence of duplex-reflux, and number of recurrent or new incompetent venous sites. The number of patients, limbs, and treated venous segments were comparable in the 6 treatment groups, also comparable for age and sex distribution. The occurrence of new varicose veins at 5 years varied from 34% for group F (surgery + sclero) and ligation (C) to 44% for the foam + sclero group (E) and 48% for group A (dose 1 sclero). At 10 years the occurrence of new veins varied from 37% in F to 56% in A. At inclusion AVP was comparable in the different groups. At 10 years the decrease in AVP and the increase in RT (indicating decrease in reflux), was generally comparable in the different groups. Also at 10 years the number of new points of major incompetence was comparable in all treatment groups. These results indicate that, when correctly performed, all treatments may be similarly effective. "Standard," low-dose sclerotherapy appears to be less effective than high-dose sclero and foam-sclerotherapy which may obtain, in selected subjects, results comparable to surgery.
