Overlapped Stenting for Treatment of an Extracranial Carotid Artery Aneurysm

Abstract

Extracranial carotid artery aneurysms (ECAAs) are rare, and their treatment is very difficult and challenging. The case of a 59-year-old woman who presented with a pulsatile mass on the left side of her neck, was diagnosed with a left-sided giant thrombosed common carotid artery aneurysm, and underwent definitive treatment by overlapped stenting, is presented. Overlapped stenting is a safe and an effective treatment procedure for ECAA. A covered stent would theoretically be reasonable and immediately effective, but its long-term patency remains unknown. Therefore, in patients lacking ischemic tolerance and those not requiring urgent intervention, overlapped stenting using uncovered stents is preferable.
