Resumo

ResumoA escleroterapia com espuma guiada por ultrassom tem ganhado espaço no tratamento da insuficiência venosa crônica secundária a varizes dos membros inferiores. Trata-se de procedimento ambulatorial, de baixo custo e sem necessidade de afastamento das atividades habituais. Apresenta bons resultados clínicos, especialmente nos estágios mais avançados da doença. Quando bem aplicada, apresenta baixas taxas de complicações maiores. Porém, a técnica apresenta altas taxas de recanalização no médio e longo prazo, e seu mecanismo ainda não é totalmente compreendido. O presente artigo descreve um caso de fístula arteriovenosa em segmento de recanalização de veia safena magna, após escleroterapia com espuma guiada por ultrassom, e identificada por exame ultrassonográfico de vigilância pós-procedimento.

Abstract

AbstractUltrasound-guided foam sclerotherapy has become widespread in the treatment of chronic venous insufficiency secondary to varicose veins. It is a low-cost, outpatient procedure that does not require medical leave. It has demonstrated good clinical results, especially in the more advanced stages of the disease. When employed correctly, it results in low rates of major complications. However, the technique exhibits high recanalization rates over mid and long-term follow up. Additionally, the recanalization mechanism has not yet been explained. This article describes an arteriovenous fistula in a recanalized segment of great saphenous vein previously treated with ultrasound-guided foam sclerotherapy that was detected during post-procedure follow-up with ultrasound.
