Traumatic arteriovenous fistula of the superficial temporal artery and vein.

Traumatic arteriovenous fistulas (AVFs) are rare, including the scalp, carotid cavernous sinus, vertebral artery and ophthalmic artery. AVF of the scalp is direct connections between the arterial feeding vessels of the scalp and the draining veins without intervening capillary beds. The draining veins are often grossly enlarged and tortuous, like a varix. We experienced a rare case of traumatic AVF involved the superficial temporal artery (STA) and the superficial temporal vein (STV). This report describes successful treatment by clipping at the fistula site and coagulation of draining STV, along with reviews of the related literatures.
