后循环缺血的治疗

The Treatment of Posterior Circulation Ischemia

后循环缺血系指椎基底动脉系统短暂性脑缺血发作和脑梗死,预后不如前循环缺血,其治疗与前循环缺血相似,但由于基底动脉闭塞病死率更高,因此通常采取更为积极的治疗,如溶栓治疗(尤其是动脉溶栓)和血管内治疗,而且治疗时间窗更长。文章对后循环缺血的治疗做了综述。

Posterior circulation ischemia refers to the transient ischemic attack and the cerebral infarction in vertebrobasilar artery system, its prognosis is not as good as anterior circulation ischemia, and its treatment is similar to that of anterior circulation ischemia. However, because of the mortality of basilar artery occlusion is higher, usually more aggressive treatment should be considered, such as thrombolytic therapy （especially intra-arterial thrombolysis） and endovascular therapy, and the therapeutic time window is much longer. This article reviews the treatment of anterior circulation ischemia.
