High flow EC-IC bypass for a giant left MCA aneurysm

Giant cerebral aneurysms may be treated through a variety of options, including aneurysm trapping with concurrent bypass. This video describes the case of a large, recurrent, left middle cerebral artery aneurysm that was treated using a high flow, radial artery bypass graft, from the external carotid artery to the left temporal M2 branch. A step-by-step operative description, with emphasis on proper microsurgical technique, is included.
