Traumatic Cavernous Carotid Fistula Following a Motor Vehicle Accident

Traumatic cavernous carotid fistulas are a rare but serious complication following blunt trauma, such as motor vehicle accidents, where the internal carotid artery is damaged, creating an abnormal connection with the cavernous sinus. This case report describes a 32-year-old female who presented with pulsatile proptosis, conjunctival chemosis, and visual disturbances following a motor vehicle accident. Imaging confirmed the presence of a traumatic cavernous carotid fistula. The patient underwent successful endovascular embolization, resulting in resolution of her symptoms. This report highlights the importance of early diagnosis and timely intervention, particularly through endovascular techniques, as the treatment of choice is to prevent long-term complications like vision loss and to restore normal ocular function.
