Abstract

Peripheral arteriovenous (AV) malformations may present with a plethora of clinical symptoms such as paradoxical emboli, severe hypertension, nerve palsies or pain syndromes. Hemodynamically compromising lesions of the limbs are rare and involve high-flow AV fistulae with marked arteriovenous shunting. A female patient with a high-flow arteriovenous malformation of the left upper-extremity is presented. Preoperative assessment by magnetic resonance imaging and magnetic resonance angiography together with a color duplex investigation revealed a hemodynamically compromising arteriovenous fistula (shunt volume 30%) involving the entire left forearm and hand. The lesion was managed operatively with a combination of selective ligation and sclerosing of the feeding artery. There was marked clinical improvement postoperatively. Magnetic resonance angiography confirmed a drastic decrease in the number and size of the arteriovenous fistulae. The shunt ratio was diminished to 10%. Although surgical treatment of arteriovenous fistulae is known to have high complication and recurrence rates, thorough preoperative planning and intraoperative monitoring, can supply the prerequisites for a favorable outcome in severe symptomatic cases.
