Traumatic Arteriovenous Fistula of the Scalp in the Left Temporoparietal Region with Intra- and Extracranial Blood Supply

Abstract EN

Traumatic AVF of the scalp is a rare abnormal vascular disease.

It is defined as a communication between the high flow arterial system and the low flow venous network, which directly connects the arterial feeding vessels of the scalp and the draining veins without an intervening capillary bed.

The superficial temporal artery (STA) was involved in 90% of the cases, and 71% of the patients only had one dominant feeding STA.

Here, we report the case of a rare large traumatic arteriovenous fistula (AVF) of the scalp that is fed by intra- and extracranial blood supply.

The clinical and radiological features are presented, and the possible pathogenesis and surgical technique are discussed.
