Direct surgery for major artery aneurysm associated with Moyamoya disease

摘要: Abstract Moyamoya disease is often accompanied by intracranial major artery aneurysms in the posterior circulation which acts as collateral channels place of stenotic internal carotid arteries. These are considered to have high risk enlargement and rupture due increased hemodynamic stress. Direct surgical intervention has been recommended for treatment these aneurysms, but direct approach them difficult interference intertwined abnormal vessels. We performed surgery seven five patients with disease. Of three located anterior were successfully clipped via pterional or interhemispheric approach. four (two at junction basilar superior cerebellar two P 1 –P 2 cerebral artery), one was approached route because vessels basal cistern judged not be rich on angiograms. However, operative field interfered abundant fragile it reach distal portion artery. In contrast, other cases subtemporal employed, there weren't any problems exposures aneurysms. Our experiences indicate that than
