Abstract：
UNASSIGNED: Duplicate origin of the middle cerebral artery (MCA) is a rare variation of MCA, often mislabeled as the fenestration of the M1 segment of MCA.
UNASSIGNED: The authors treated an unruptured aneurysm, 8 mm in diameter, associated with a duplicate origin of MCA in a 42-year-old woman who underwent magnetic resonance imaging for transient vertigo. Clipping surgery was inapplicable due to the lack of space to insert clip blades between the neck and two origins of MCA. Under stent-assisted maneuver, the aneurysm sac was successfully obliterated using three coils, resulting in Raymond-Roy class 1 occlusion status. Digital subtraction angiography performed 3 months after the embolization showed complete obliteration of the aneurysm. So far, only 11 patients with aneurysms associated with duplicate origin of MCA have been reported. We performed a literature review of this very rare combination. The size of aneurysms ranged from 2 to 8 mm, with a mean of 5.2 mm. The neck of the aneurysm is mainly located at the corner between the inferior limb and the internal carotid artery. Ours is the youngest and has the largest aneurysm.
UNASSIGNED: Aneurysm can arise from duplicate origin of MCA, for which stent-assisted coiling may be an appropriate treatment modality.

摘要：
■大脑中动脉（MCA）的重复起源是MCA的罕见变异，通常错误标记为MCAM1段的开窗。
■作者治疗了未破裂的动脉瘤，直径8毫米，与一名42岁女性因短暂性眩晕而接受磁共振成像的MCA重复起源有关。由于缺乏在颈部和MCA的两个起点之间插入夹片的空间，因此夹钳手术不适用。在支架辅助操作下，使用三个线圈成功消除了动脉瘤囊，导致雷蒙德-罗伊1级闭塞状态。栓塞后3个月进行的数字减影血管造影显示动脉瘤完全闭塞。到目前为止,仅有11例与MCA来源重复相关的动脉瘤患者被报道.我们对这种非常罕见的组合进行了文献综述。动脉瘤的大小范围从2到8毫米，平均5.2毫米。动脉瘤的颈部主要位于下肢和颈内动脉之间的角落。我们的是最年轻的，有最大的动脉瘤。
■动脉瘤可由MCA的重复起源引起，支架辅助卷绕可能是一种合适的治疗方式。
