Surgical and endovascular management of arteriovenous malformation: case series from a single center.

Management of arteriovenous malformation (AVM) remains a major challenge to vascular surgeons. A multidisciplinary approach was introduced in our hospital to manage these cases from October 2003 to date. This is a report of our experience in their management. A prospective study was done on all patients with symptomatic AVM admitted to our unit between October 2003 and May 2006. All patients had preoperative duplex scanning and magnetic resonance imaging with or without conventional angiography. A multidisciplinary team assessed and treated these cases according to the type of malformation. Thirty-two cases were included in this study, with a mean follow-up of 18.3 months. Of these, 20 cases were predominantly venous and treated with surgical excision (n = 14) or ethanol sclerotherapy (n = 6). Twelve cases were predominantly arterial or arteriovenous shunting; 10 were treated with preoperative embolization followed by surgical excision and the remaining 2 with superselective embolization alone. The overall complication rate was high (31%). However, all were minor and settled down conservatively. No recurrence was observed in the early follow-up period. Management of AVM by a surgical and endovascular approach can deliver excellent results, with acceptable morbidity and no recurrence in the early follow-up period.
