A Case of Blunt Traumatic Arteriovenous Malformation of the Forearm.

Abstract

Arteriovenous malformation(AVM) is classified as either congenital or traumatic (acquired) in origin.Most cases are congenital, with traumatic AVM relatively rare in Japan.About 30 traumatic AVM cases have been reported in the literature, only 5 (16.7%) of these cases were caused by blunt trauma.We surgically treated a blunttraumatic AVM of the forearm which existed in the flexor pollicis longus muscle and obtained a satisfactory surgical result.
