Abstract:
Extracranial carotid artery aneurysms (ECAAs) are rare and extremely challenging disease entities. Untreated ECAAs can lead to serious neurologic sequelae, primarily from thromboembolism. Because of the high incidence of major neurologic complications, surgical intervention is warranted in most cases. We report a 63-year-old woman with voice fatigue and difficulty swallowing. Upon work-up, we discovered bilateral giant ECAAs and treated them with a combination of aneurysmectomy, primary anastomosis, and an interposition polytetrafluoroethylene graft. Unique features of the aneurysms include their unprecedented size and bilaterality, which is exceedingly rare.
