Regional cerebral perfusion and ischemic status after standard superficial temporal artery–middle cerebral artery (STA-MCA) bypass surgery in ischemic cerebrovascular disease

摘要

Background and purpose  Standard superficial temporal artery–middle cerebral artery (STA-MCA) bypass surgery is an effective treatment for ischemic cerebrovascular diseases, including moyamoya disease and occlusive cerebrovascular disease. Our purpose in this study was to evaluate the ischemic status based on the imaging modality of computed tomographic perfusion (CTP) before and after STA-MCA bypass in patients with moyamoya disease and occlusive cerebrovascular disease.
