脉络膜前动脉动脉瘤为罕见的颅内动脉瘤，其发病率占所有颅内动脉瘤的2%~5%。因脉络膜前动脉细小且缺乏有效侧枝代偿，在治疗时容易引起脉络膜前动脉损伤缺血，从而导致脉络膜前动脉综合征。目前学者们发表了大量关于脉络膜前动脉动脉瘤手术治疗及血管内治疗的文献，但仍然缺少相关综述性文章，本文对脉络膜前动脉动脉瘤治疗相关的缺血风险及治疗策略综述如下。

Anterior choroidal artery aneurysms are rare intracranial aneurysms, accounting for 2%-5% of the incidence of all intracranial aneurysms. Because the anterior choroidal artery is a small artery with lacks of effective collateral compensation, it is easy to cause anterior choroidal artery injury and ischemia to lead to anterior choroidal artery syndrome in the treatment of aneurysms. At present, scholars have published a large number of literatures on the surgical and endovascular treatment of anterior choroidal artery aneurysm, but there is still a lack of relevant review articles. This study summarizes the treatment of prechoroidal artery aneurysm related ischemic risk and treatment strategies as follows.
