Abstract
An adult case who had been suffering from chronic cerebral infarction with right anterior and middle cerebral artery occlusion is reported. Encephalo-duro-arterio-synangiosis (EDAS), an indirect EC-IC anastomosis, was performed on the patient, resulting in a good revascularization of the brain. The case was a normotensive patient who had no history of meningitis, hypertension or diabetes mellitus. Since no adequate cortical branches were opacif ied by cerebral arteriogram, the EDAS operation was selected. Arteriogram obtained 3 months and 7 months postoperatively, demonstrated a gradual cerebral revascularization with dilated STA. Though it is generally thought that vascularization is insufficient in adults, EDAS as an indirect EC-IC anastomosis, may be indicated in cases where an adequate recipient artery is not available like in this patient.
