From: Management of large or giant Extracranial carotid artery aneurysms: a single-center experience
Typical case 2; A 71-year-old male with hyperlipidemia and a smoking habit of 1 pack per day presented with a pulastile neck mass that had been present for 4 months. The mass was observed on the right side of the neck (A), and the patient was found to be neurologically intact upon examination. Further investigation through a CTA examination revealed an unruptured aneurysm in the right ECCA (B). Cerebral angiogram revealed a giant aneurysm (21.0 mm in maximum diameter) on the extracranial internal carotid artery (C), and was reconstructed with a 4.0·16 mm Willis (D). One month after the operation, the patient took oral anti-infective drugs. Upon re-examination angiography, it was found that the aneurysm had completely disappeared and the blood flow through the parent artery was smooth (E). Additionally, the pulsating mass in the neck had also disappeared (F)
