Fenestration of the middle cerebral artery (MCA) is an unusual anomaly. We recognized and photographed MCA fenestration during an operation performed to clip an internal carotid artery aneurysm. The incidence of angiographic demonstration of this anomaly has been reported to be 0.26%. The clinical significance of fenestration of the vertebral and basilar arteries has primarily been the relationship of fenestration with other intracranial vascular anomalies. This is the first report of MCA fenestration associated with an aneurysm.
大脑中动脉（MCA）开窗是一种罕见的异常情况。我们在进行夹闭颈内动脉瘤的手术过程中识别并拍摄到了大脑中动脉开窗。据报道，这种异常情况的血管造影显示发生率为0.26%。椎动脉和基底动脉开窗的临床意义主要在于开窗与其他颅内血管异常的关系。这是第一例与动脉瘤相关的大脑中动脉开窗的报道。
