Aneurysmectomy and graft interposition for giant thrombosed proximal internal carotid artery aneurysm: Technical details.

A giant thrombosed extracranial internal carotid artery aneurysm (ECCA) is extremely rare and its treatment is challenging. Despite the advance of endovascular technique, open surgery is still considered a first-line treatment in giant thrombosed ECCA. We describe a case of giant thrombosed ECCA which was successfully treated by aneurysmectomy and graft interposition with the technical details.
