1. Twenty-nine patients with "Moyamoya" disease underwent ST·MC anastomosis and encephalo-myo-synangiosis. The duration of follow-up study after surgery was ranged from 3 years 6 months to 6 years 9 months (mean 4 years 5 months). 2. Motor weakness, sensory disturbance, speech disturbance and involuntary movement were observed preoperatively in 25 cases, 9 cases, 13 cases and 3 cases respectively, but these neurological deficits disappeared postoperatively in 5, 6, 8 and 1 cases respectively. Though the deficits remained in the other cases, these improved markedly in the most of the cases. 3. The disturbance of intelligence was observed in 13 cases preoperatively. In 4 of them, it disappeared postoperatively. Only 2 cases had less than 70 of I.Q. (Intelligence Quotient) and 6 cases had more than 80 of I.Q. 4. Regarding to homonymous hemianopsia, visual disturbance and disturbance of swallowing, the operation was non-effective. 5. As to the operative result, 11 cases recovered completely, 14 improved remarkably, 1 improved slightly, and 2 adult cases were unchanged and 1 case died of myocardial infarction one year after surgery. 6. All the cases were classified by ADL: 13 cases; excellent, 8 cases; good, 6 cases; fair, 1 case; poor and 1 case; dead.
