[Saphenous vein graft bypass from the external carotid artery to the supraclinoid internal carotid artery to treat a giant aneurysm of the cavernous internal carotid: case report].
Alternative surgical procedures to treat unclippable aneurysms of the intracavernous carotid artery include proximal vessel occlusion and trapping. Those techniques, even in patients with rich collateral vessels, are associated with risk of hemodynamic compromise and ischemic complications. Therefore, a safe treatment requires revascularization to maintain blood flow to the involved territories. We report the case of a 47-year-old female, with ischemic signs and symptoms and a right third nerve palsy caused by a giant aneurysm, partially trombosed, of the intracavernous carotid artery. The patient was submitted to trapping after a saphenous vein graft bypass from the external carotid artery to the supraclinoid internal carotid artery. The surgical result was good without complications.
