Radical surgery of a galenic aneurysm with regional cerebral blood flow analysis. A case report.
Successful surgical treatment of a case of aneurysm of the vein of Galen is presented. An 11-month-old boy was admitted with episodes of convulsive attacks. Neuroradiological examination revealed an aneurysm of the vein of Galen filled by branches of posterior cerebral arteries and left thalamoperforating artery. Regional cerebral blood flow, which was measured by a method of xenon-enhanced computed tomography, showed a low flow area in the frontal and occipital regions. The aneurysm was approached through the bilateral parietooccipital interhemisphere, freed from the feeders, and ligated. During the operation, cortical blood flow was monitored for prevention of normal perfusion pressure breakthrough. After the feeders were successfully clipped, the blood flow increased and became normalized in the related cortex. There was no postoperative neurological deterioration.
