Treatment of giant cavernous aneurysm in an elderly patient via extracranial–intracranial saphenous vein bypass graft in a hybrid operating room

摘要

Rationale:Extracranial–intracranial saphenous vein bypass (EC-IC SVB) remains indispensable for treating giant cavernous aneurysms. We report an unusual case of a giant cavernous aneurysm in an elderly patient treated with EC-IC SVB in a hybrid operating room. Immediately following proximal ligation of the internal carotid artery (ICA), she suffered an acute intraoperative encephalocele.
