Vaso CT在椎-基底动脉结合部闭塞再通术中的应用

目的探讨Vaso CT检查的影像特征对椎-基底动脉结合部闭塞再通术的风险评估、指导作用及临床价值。方法回顾性纳入解放军总医院神经内科2016年1月至2017年5月收治的14例椎-基底动脉结合部闭塞患者,术前均行全脑DSA确认椎-基底动脉结合部闭塞,采用Vaso CT测量闭塞血管长度及其两端血管走形,根据结果评估手术风险并指导椎-基底动脉结合部闭塞再通术。结果 14例患者椎-基底动脉结合部闭塞血管长度为2.56~19.09 mm,平均(4.5±2.1)mm,对其中13例患者行椎-基底动脉闭塞再通术,12例患者血管成功开通,并均于血管开通后行支架置入术,其中置入Solitaire支架8枚及Wingspan支架4枚;1例患者因闭塞长度较长(19.09 mm)而未进行血管开通术。所有手术患者未发生围手术期并发症,术后患者神经功能症状均明显改善。结论 Vaso CT可对椎-基底动脉结合部闭塞开通术的手术风险进行准确判断,并可指导手术路径,降低患者围手术期并发症发生风险,提高手术成功率。

Application of Vaso CT in the recanalization of vertebrobasilar junction occlusion

Objective To investigate the risk assessment,guiding role,and clinical value of Vaso CT image features for recanalization of vertebrobasilar junction occlusion. Methods From January 2016 to May 2017,14 patients with vertebrobasilar junction occlusion admitted to the Department of Neurology, Chinese PLA General Hospital were analyzed retrospectively. Preoperative cerebral angiography confirmed vertebrobasilar junction occlusion. Vaso CT was used to measure the length of the occluded vessels and vascular direction at both ends. According to these results, the operative risks were evaluated and the recanalization of vertebrobasilar junction occlusion were guided. Results The length of vertebrobasilar junction occlusion was 2. 56-19. 09 mm (mean 4. 5 ± 2. 1 mm) in 14 patients,and 13 of them were treated with the recanalization of vertebrobasilar artery occlusion,the blood vessels of 12 cases were successfully recanalized and stent placement was performed after the recanalization,among them,8 Solitaire stents and 4 Wingspan stents were implanted;One patient did not perform recanalization because of longer length of occlusion (19. 09 mm). All patients operated did not have any perioperative complications, and the neurological symptoms were significantly improved after procedure. Conclusion Vaso CT can accurately determine the surgical risk of the recanalization of vertebrobasilar junction occlusion,and can guide the surgical pathways,reduce the incidence of perioperative complications,and improve the success rate of the operation.
