The authors have analized morphological changes of cerebral vasculature following STA-MCA anastomosis performed on 4 adult cases with Moyamoya disease. The analysis was made by repeated angiography following the anastomosis. The first follow-up angiography was made 14 to 16 days after the surgery and the second ones were performed 6 to 24 months later.<BR>In postoperative follow-up angiography, the authors have recognized disappearance or remarkable decrease of "Moyamoya" vessels at the base of the brain and remarked dilatation of the anastomosed superficial temporal artery.<BR>On the basis of these findings, the authors believe that the STA-MCA anastomosis not only increases the cerebral blood flow but also it should have a preventive effect on hemorrhage from the abnormally dilated collateral blood vessels, which is the largest cause of death in this disease.
