Since the pathogenesis of so-called moyamoya disease is still unknown, no definitive method of treatment has been established for this condition. The authors report the results of 5 superficial temporalmiddle cerebral artery (STA-MCA) anastomoses, performed on 3 adult cases with so-called moyamoya disease.<BR>The follow-up period ranged from 6 months to 21 months. Excellent results were obtained in two cases, and a fair result in the other.<BR>In all the cases, follow-up angiograms revealed a wide patency of the anastomoses with appreciable increase of natural cerebral vasculature, and disappearance of the abnormal vascular networks (moyamoya vessels) at the base of the brain.<BR>The disappearance of the moyamoya vessels following the surgery supports the theory that the moyamoya vessels are the collaterals which have been developed following occlusion of the major vessels at the base of the brain.<BR>From the therapeutic point of view, it is obvious that the creation of the new collateral by means of STA-MCA anastomosis increases blood supply to the brain. Also, this creation of the new collateral can be expected to decrease chances of hemorrhaging from the moyamoya vessels as the vessels markedly decreased or disappeared following the surgery.
