Ecoescleroterapia com espuma no tratamento da insuficiência venosa crônica

Abstract

Objective: To describe the results of foam sclerotherapy in the treatment of chronic venous insufficiency. Materials and Methods: Longitudinal study of cases developed in the period between January of 2007 and November of 2009, with 18 patients with venous insufficiency treated with ultrasound-guided foam sclerotherapy in a private clinic. The Tessari's method was utilized to produce the foam and the length of the patients' follow-up varied from 4 to 44 months. Total occlusion of the treated vein and complete ulcer reepithelialization were the primary outcomes, and the secondary ones were vein caliber reduction, aesthetic improvement and patient's satisfaction. Results: The rate of total or partial occlusion achieved 83.4% in the first review (55.6% total and 27.8% partial) and 66% (44.4% total and 22.2% partial) among the patients who underwent a second review. The rate of varicose veins occlusion achieved 80% and the rate of ulcer healing achieved 70%. Conclusion: Ultrasound-guided sclerotherapy has demonstrated to be a safe and effective procedure for the management of chronic venous insufficiency in this group of patients. The incidence of complications was minimal and most of the patients reported satisfaction with the results of the treatment.© Colégio Brasileiro de Radiologia e Diagnóstico por Imagem.
