ИЗМЕНЕНИЯ МОЗГОВОЙ ПЕРФУЗИИ ПРИ ЭКСТРА-ИНТРАКРАНИ-АЛЬНОМ МИКРОАНАСТОМОЗЕ ПРИ ХРОНИЧЕСКОЙ ОККЛЮЗИИ ВНУТРЕННЕЙ СОННОЙ АРТЕРИИ

Chronic occlusion of internal carotid artery is one of leading reason for brain ischemia. For treating of chronic ICA occlusion EC/IC bypass is used. Aim of the study was to estimate changes of brain perfusion before and after EC/IC bypass. After operation estimation performed in three days. In patients with reduced CBV before EC/IC bypass, there were significant changes of perfusion after operation. For patients with without significant differences of CBV between brain hemispheres changes were not reliable. According to this findings indications for EC/IC bypass must be limited and patients should undergo operation only if it proposed to be effective.
