Abstract

Arteriovenous malformations represent a direct connection between the arterial and the venous systems. AVMs are usually present at birth but may not be clinically evident. They become evident in childhood and are often exacerbated during puberty or pregnancy.Closer examination reveals increased temperature, dilated veins, and a thrill that is usually noted at palpation. These lesions can be dangerous when they are in evolution. Cutaneous ischemia with ulceration or infection and haemorrhage are the most common local complications. If the malformation is extensive, high-output cardiac failure can be seen. Vascular malformations of the extremities present a difficult therapeutic challenge. Ligation of feeding vessels may lead to tissue necrosis and limb loss and can make subsequent attempts at transcatheter therapy impossible. The purpose of this study was to review our results with transcatheter and percutanous embolization therapy in symptomatic extremities vascular malformations in 30 patients seen at our interventional unite.
