前循环串联闭塞是急性大血管闭塞的一种特殊类型，多数文献将其定义为颅内大血管闭塞和同侧颅外颈内动脉高度狭窄或闭塞的组合。目前，大约15%接受血管内治疗的前循环急性缺血性卒中患者为串联闭塞。有数据表明，血管内治疗对串联闭塞患者效果优于药物治疗，然而关于其血管内治疗的最佳方案仍存在争议。本文围绕近年来前循环串联闭塞的血管内治疗进展进行综述，以期提高急性前循环串联闭塞性缺血性卒中患者的整体救治水平。

Tandem occlusion of the anterior circulation is a specific acute large vessel occlusion, which is defined in most of the literature as a combination of intracranial large vessel occlusion and high degree of stenosis or occlusion of the ipsilateral extracranial internal carotid artery.Tandem occlusion is presented in approximately 15% patients with acute ischemic stroke in the anterior circulation who receive endovascular treatment. In patients with tandem occlusion, endovascular treatment is more effective than drug therapy; however, controversy still exists regarding the optimal management strategy of endovascular treatment. This article reviews the recent advance in endovascular treatment of tandem occlusion in the anterior circulation in recent years, to improve the overall care standard for acute ischemic stroke with tandem occlusion of the anterior circulation.
