Arteriovenous Fistula After Superficial Temporal Artery Biopsy

Arteriovenous fistula of the superficial temporal artery is quite rare. If it occurs, it is most often caused by trauma to the temporal region where the artery is very superficial to the skin. We present the first reported case of an arteriovenous fistula after temporal artery biopsy and review the literature on the pathophysiology, diagnosis, and treatment of arteriovenous fistula.
