Summary:Progressive worsening of atherosclerotic intracranial arterial stenosis is difficult to manage. When atherosclerotic plaques are severe and unstable, expansion using endovascular methods is unsafe. To restore hemodynamic insufficiency, placing a distal bypass without irritating the unstable plaques may be safer. We present seven cases of progressive atherosclerotic middle cerebral artery (MCA) stenosis treated with consecutive superficial temporal artery (STA)–MCA double-bypass. In all cases, mid- to long-term bypass patency without post-operative infarction was confirmed using MRA. Meticulous STA donor preparation and precise approximation of the intima of both donor and recipient during anastomosis are key.
