目的：探讨后循环缺血（posterior circulation ischemia ，PCI）的影像特征及临床表现。方法回顾性分析我院72例 PC I患者临床资料，观察其影像特点、临床表现及预后。结果 PC I以老年人多见，72例患者中确诊基底动脉尖部综合症（12例）、椎基底动脉扩张延长症（8例）、延髓背外侧综合征（3例）、中脑大脑脚综合征（1例）、中枢神经系统性血管炎（2例）、一过性脑血管痉挛（8例）、高血压脑病（1例）。其相关疾病影像表现以缺血梗死为主，病灶及其分布又各具特征性。临床症状、体征亦呈多样化特点，多以眩晕、意识障碍、眼球运动障碍、皮质盲或偏盲、偏瘫起病。结论后循环障碍临床及影像表现复杂多样，部份疾病预后差，临床医师应高度重视，尽早完善 MRI检查避免误诊及漏诊，改善预后提高患者生存率。

Objective To investigate the clinical characteristics of posterior circulation ischemia (PCI) .Methods The clinical datas of 72 patients with posterior circulation ischemia in our hospital from February 2010 to August 2013 were ret‐rospectively analized in terms of clinical manifestation ,image characteristics and prognosis .Results PCI mostly occurs in aged people .Among those ,16 cases presented with Top of the basilar syndrome (TOBS) ,8 cases with vertebrobasilar dolichoectasia ,3 cases with Wallenberg syndrome ,1 case with weber syndrome ,1 case with cerebral vasculitis ,8 cases with trensient ischemic attack ,and 1 case with hypertensive encephalopathy .Their clinical symptoms and imaging findings were diversified in characteristics .Conclusion PCI clinical manifestation and image characteristics are complicated ,the prognosis of some patients is poor ,clinical physicians should be vigilant and performed M RI as soon as possible to avoid misdiagnosis .
