Safety and efficiency of perilesional sclerotherapy in leg ulcer patients with postthrombotic syndrome and/or oral anticoagulation with phenprocoumon.

BACKGROUND

The positive effects of perilesional sclerotherapy for venous leg ulcers is well documented. Although many patients with venous leg ulcers require oral anticoagulation or have had a deep vein thrombosis, the effects of these factors on perilesional sclerotherapy are unknown. The aim of this study was to review effects of oral anticoagulation and/or postthrombotic syndrome on perilesional sclerotherapy.

PATIENTS AND

METHODS

28 patients with venous leg ulcers were observed. 12/28 had a postthrombotic syndrome, 5/12 were on oral anticoagulants (phenprocoumon with INR 2-3). During each treatment session, 1 ml sclerosing foam (1:5, polidocanol 2 %, method of Tessari) was injected. Treatment was continued until all extrafascial veins in the 15cm surrounding the ulcer were closed.

RESULTS

Closure of the perilesional veins was achieved in all patients with 2.5 +/- 1.8 injections. In 10 of 28 patients (35.7 %), just one injection was needed. More injections were needed, both in patients with postthrombotic syndrome (3.3 +/- 2.1 vs. 1.8 +/- 1.3) and on anticoagulation with phenprocoumon (4.2 +/- 1.2 vs. 2.1 +/- 1.7). There were only two complications: an ascending phlebitis up to the accessory saphenous vein and a superficial erosion at an injection site which healed within 1 week.

CONCLUSIONS

Perilesional sclerotherapy with foam is a safe and efficient therapy for patients with chronic venous leg ulcers even with postthrombotic syndrome and/ or ongoing anticoagulation.
