Superficial temporal artery to middle cerebral artery bypass with interposed saphenous vein graft in patients with atherosclerotic internal carotid artery occlusive disease and impaired cerebral hemodynamics.

Background: The aim of this study was to evaluate the efficacy of interposed saphenous vein graft (SVG) usage during extracranial-intracranial (EC-IC) bypass surgery in patients with cerebral ischemia and appropriate donor artery absence.

Methods: Since October 2010 till January 2014, 62 EC-IC bypass surgeries were applied in 60 patients. In nineteen patients SVG was used to create low-flow bypasses between superficial temporal artery trunk and cortical segment of middle cerebral artery.
