    Abstract:
    The character of blood supply to the affected cerebral hemisphere was studied on the basis of angiography performed before and after occlusion of the afferent vessels of large arteriovenous aneurysms in 90 patients and study of cerebral circulation on a gamma chamber in 30 patients. It was established that the affected cerebral hemisphere is supplied with blood from the vascular basin of the same side. The importance of the regional blood flow is determined by the localization and the sources of blood supply to the aneurysm. Before the operation, the maximum decrease of regional blood flow was found in zones with contiguous blood supply, namely in the parietal and parieto-temporal areas. The occlusion of afferent vessels of the aneurysm leads to an increase in the flow of blood aneurysm is supplied with blood from the cortical arterio-arterial anastomoses in the zones of contiguous blood supply.
