Long-Term Follow-up Study of STA-MCA Anastomosis and EMS in Moyamoya Disease
The condition of 62 children with moyamoya disease was followed after cerebral revascularization. The mean follow-up period was 87 months. For revascularization, 42 cases were treated with superficial temporal artery—middle cerebral artery (STA-MCA) anastomosis and encephalomyosynangiosis (EMS) on both sides, nine with only EMS on both sides, and the remaining 11 with STA-MCA anastomosis on one side and with EMS on the other side. Clinical improvement was obtained in 61 among 62 cases. Complete remission without any neurological deficits was obtained in 27 cases. Speech disturbance worsened in the remaining one. Though postoperative improvement in the motor and speech function was satisfactory in most of the cases, these surgical procedures could not restore the visual field defect caused by completed stroke. Minor deficits in the intellectual function persisted in 14 cases.
