Acute Pre-operative Infarcts and Poor Cerebrovascular Reserve are Independent Risk Factors for Severe Ischemic Complications Following Direct Extracranial-Intracranial Bypass for Moyamoya Disease

摘要

Background and PurposeSevere ischemic changes are a rare but devastating complication following direct superficial temporal artery to middle cerebral artery (STA MCA) bypass in Moyamoya patients. This study was undertaken to determine whether pre-operative MR imaging and/or cerebrovascular reserve (CVR) assessment using reference standard stable xenon enhanced computed tomography (xeCT) could predict such complications.
