Pelvic arteriovenous malformation with iliac vein thrombosis - A case report

Background. Congenital arteriovenous malformations (AVMs) of the pelvis are relatively rare and are difficult to treat because of diffuse extension and the number of feeding vessels. Methods. We describe a patient with a pelvic AVM with shunts who also developed iliac vein thrombosis. The AVM was diagnosed during evaluation of what had initially appeared to be a venous stasis ulcer. Results. The ulcer was successfully treated by Palma's procedure, partial resection of the feeding vessels, and transcatheter arterial embolization. Conclusions. Coexistence of a pelvic AVM with an iliac vein thrombosis has not previously been reported.
