Endovascular Treatment of a Giant Intracranial Aneurysm with a Stent-Graft

Abstract

This report describes a giant intracavernous carotid aneurysm successfully treated by the placement of a single covered stent. A 40-year-old woman was admitted with a progressive diplopia in relation with palsy of the IV and VI cranial nerves. Magnetic resonance imaging revealed an intracavernous giant aneurysm located at the bifurcation between the origin of a trigeminal artery and the intracavernous portion of the right internal carotid artery. A covered stent was successfully placed, and complete exclusion of the aneurysm was confirmed at 11-month follow-up angiography. The use of covered stents in intracranial vascular structures can now be a feasible way of treating selected cases of wide-necked intracranial aneurysms.
