We angiographically studied 80 patients within 6 hours after the onset of ischemic supratentorial infarction. From this group we selected 36 with middle cerebral artery occlusion who survived. In these patients, compared presence a collateral blood supply during early phase extent final parenchymal brain damage obtained by computed tomography 3 months event. The circulation first few stroke reduced size in stem-trunk occlusion. was more efficient had no significant stenosing lesions extracranial internal carotid artery. Our data confirm that lenticulostriate arteries are end not supplied vessels and suggest formerly thought to be caused hemodynamic mechanisms (watershed infarcts) or arteriolar (lacunar may due occlusions.
