Abstract

Arterial dissection is caused by intima damage and blood flow into the vascular wall, resulting in the separation of the intima and middle layer, intramural hematoma formation, and subsequently stenosis, occlusion, or aneurysm. A 68-year-old woman with bilateral common carotid artery dissection (CAD) caused by a dog bite two months prior was admitted to the hospital. Cerebral angiography, magnetic resonance angiography (MRA), and carotid color Doppler ultrasonography showed right CAD (aneurysm formation) with luminal stenosis (50%-69%), left common CAD (intramural hematoma formation). Bilateral common CAD caused by a dog bite is rare. The mechanism of CAD may be similar to iatrogenic dissection. After eliminating the contraindication of operation, right common carotid artery stenting was performed two months after conservative treatment.
