Intravascular Treatment for Arteriovenous Malformations in Extremities

Abstract

Extremities are one of the favorite sites of AVM. Intravascular treatment of the area plays an important role because it is easy relatively to approach the nidus by trans-arterial or trans-venous route and percutaneous puncture. It is necessary to prevent flowing-out of sclerosant agents to proximal normal veins and to remain sclerosant agent into the target vascular as long as possible when sclerotherapy is performed. Certain flow control can be performed in lesions of extremities. Selection of the best treatment for each patient according to precise evaluation of anatomy and flow-model of lesions is important for achievement of the treatment outcome and prevention of complications.
