We report a unique case of an anterior cerebral artery aneurysm in a patient with embryonic unfused middle cerebral artery anomaly. The arterial twigs of the middle cerebral artery supply the entire middle cerebral artery territory including the lenticulostriate branches. There was a vessel incorporated into the aneurysm, which was referred to as an accessory middle cerebral artery and it gave rise to a lenticulostriate branch. The aneurysm was occluded with detachable coils using a remodeling technique. After successful occlusion of the aneurysm the so-called accessory middle cerebral artery including its lenticulostriate branch started to fill from the anomalous middle cerebral artery network and the patient did not experience any ischemic injury.
我们报告了一例独特的病例，该患者患有胚胎期未融合的大脑中动脉异常，同时存在大脑前动脉动脉瘤。大脑中动脉的分支供应整个大脑中动脉区域，包括豆纹动脉分支。动脉瘤内有一支血管，被称为副大脑中动脉，它发出一条豆纹动脉分支。采用重塑技术用可脱卸弹簧圈栓塞动脉瘤。成功栓塞动脉瘤后，所谓的副大脑中动脉及其豆纹动脉分支开始从异常的大脑中动脉网络供血，患者未出现任何缺血性损伤。
