Abstract

Abstract High-voltage electrical burns can cause immediate and long-term neurological and cerebrovascular injuries. The authors present a 21-year-old man who developed an intracranial arteriovenous fistula secondary to high-voltage electrical injury. CT angiography demonstrated a left supraclinoid internal carotid artery (ICA)–inferior petrosal sinus (IPS) fistula. A subsequent angiogram revealed an irregularity of the cavernous and supraclinoid ICA with stenosis involving the supraclinoid segment and a fistulous connection between the ICA and IPS distal to the ophthalmic take-off and proximal to the anterior choroidal artery. The patient underwent a decompressive hemicraniectomy and clip-wrapping of his ICA pseudoaneurysm with successful obliteration of the fistulous connection. To our knowledge, this is the first report of an intracranial arteriovenous fistula secondary to an electrical burn injury.
