Paraplegia due to posttraumatic pelvic arteriovenous fistula treated by surgery and embolization

Abstract

A case is presented in which a posttraumatic pelvic arteriovenous fistula caused progressive paraplegia because of voluminous shunting into the epidural venous system. Surgical ligation and transcatheter embolization of major and minor arterial feeders decreased shunt flow sufficiently to permit direct embolization of the fistula by an injectable plastic. This combined approach may allow obliteration of unresectable acquired or congenital arteriovenous malformations.
