Digital Arteriovenous Fistula Formation Associated with Bone Fracture Induced Blunt Trauma

Keisuke Miyake et al. Int J Angiol. 2019 Jun.

Abstract

An arteriovenous fistula formation caused by a blunt trauma is a quite rare complication, especially in the hand. We report an extremely rare case of a traumatic arteriovenous formation in a finger that developed 5 years after the patient received a blunt trauma in conjunction with a phalangeal bone fracture. Successful management was achieved by direct surgical resection of the arteriovenous fistula without any complication.

Keywords: arteriovenous fistula; artery; delayed presentation; fistula; trauma.
