Superficial temporal artery-middle cerebral artery bypass combining with original encephaloduromyosynangiosis to treatment of moyamoya disease in adults

Abstract

Objective To study the therapeutic effect of superficial temporal artery-middle cerebral artery (STA-MCA)anastomosis combining with original encephaloduromyosynangiosis in adults with moyamoya disease.Methods 23 direct STA-MCA bypasses combining with encephaloduromyosynangiosis were performed on 23 hemispheres in 18 cases of ischemic-type and 5 cases of hemorrlogic-type moyamoya disease.Results The cerebral blood flow increased immediately aher operation.The ischemic symptoms were relieved in all the patients.No rebleeding was found on follow up.There's a complication of operation related sinall infarction.Conclusion Indirect revascularization using temporal muscle(the deep temporal artery)and the dura mater(the middle meningeal artery)is named asencephaloduromyosynangiosis(EDMS).The combination of STA-MCA bypass with EDMS is a rational approach in treating of adult moyamoya disease.
