Abstract

Extracranial carotid artery aneurysms, although seen rarely, must be paid attention as it may cause potential fatal complications such as thromboemboli and rupturation. 44 year-old female admitted to our clinic with a progressive bulging mass since 5 years on left side of her neck. No neurologic symptom like stroke, transient ischemic attack or cranial nerve dysfunction was detected. Initial investigation with duplex ultrasound demonstrated saccular aneurysm of the internal carotid artery on the left. On MRI a 16x25 mm sacculer aneurysm was revealed on 3cm distal part of common carotid bifurcation. Internal carotid artery was anastomosed with end-to-end technique following resection of aneurismatic segment.
