The authors report the case of a patient who presented a ruptured aneurysm of the anterior communicating artery and an unruptured aneurysm of the middle cerebral artery arising at the site of a fenestration of the MCA. The fenestration was undiagnosed on the preoperative angiogram but discovered during the surgery carried out for clipping of the aneurysms. In the literature, cases of fenestration of the MCA are sporadically reported and are incidental findings; an aneurysm may be associated on an artery other than the fenestrated MCA; an aneurysm arising at the site of the MCA fenestration is a very rare occurrence.
作者报告了一例患者，该患者前交通动脉动脉瘤破裂，大脑中动脉开窗处出现未破裂动脉瘤。术前血管造影未诊断出开窗情况，而是在为夹闭动脉瘤进行手术时发现的。在文献中，大脑中动脉开窗的病例报告较为零散，多为偶然发现；在除开窗的大脑中动脉之外的其他动脉上可能伴有动脉瘤；在大脑中动脉开窗处出现的动脉瘤极为罕见。
