椎基底动脉急、慢性闭塞腔内开通的初步经验

目的评价颅内段椎动脉、基底动脉闭塞腔内再开通的可行性、安全性及疗效。方法 11例优势椎动脉颅内段、基底动脉闭塞患者行腔内开通,记录分析术中各种并发症和相关危险因素,比较开通前、开通后及随访期间TIMI血流分级、mRS评分。结果 9例开通（成功率80%）,闭塞远端中位TIMI血流分级由术前的1级提升到术后的3级（P〈0.05）;中位mRS评分术前5分,术后48 h为5分,3个月随访为4分（P〉0.05）。1例椎动脉支架成形结合基底动脉接触溶栓并发颞叶出血,脑干新发梗死2例（其中1例术中基底动脉夹层,开通失败）,围手术期并发症总计3例、发生率27. 3%。亚组分析提示单纯椎动脉颅内段闭塞可能较基底动脉受累再开通率高、并发症少、临床预后较好。结论椎基底动脉闭塞腔内开通技术可行,术后血流分级和mRS评分有所改善,但鉴于其并发症发生率高、部分患者预后差,临床应严格筛选病例、谨慎开展。

Endovascular recanalization of the acnte and chronic occluded vertebrobasilar artery:Initinal clinical experience and technical considerations

Objective To evaluate the feasibility,safety and efficacy of endovacular recanalization in patients with acute and chronic occluded vertebrovacular artery.Methods Eleven patients with occluded vertebrovascular artery were treated.We recorded the variation of image and clinical manifestation,then analyzed the correlated dangerous elements and evaluated treatment effect by comparing the modified Rankin Scale scores and recanalized bloodstream TIMI scores for all patients among preoperation,postoperation and f...
