摘要
目的 探讨颈内动脉狭窄的血管内支架治疗方法 ,选择手术方法。方法 选择颈内动脉狭窄≥ 80 %的患者 18例 ,围手术期进行抗凝治疗 ,全部行全脑血管造影及颈部超声检查。采用 2类 3种不同支架 ,分预扩与不预扩两种操作。 18例均使用“导引导管衬管”和“颈外动脉支撑”技术。结果 18例操作顺利 ,无临床并发症 ,影像学评价完全成功 ,超声波检查脑血流恢复正常或好转 ;15例临床症状消失 ;3例临床症状不同程度好转。 3至 2 4个月随访脑血管造影及超声波复查支架形态良好 ,血流通畅 ,血管无再狭窄。结论 采用正确的围手术期治疗、及手术方法颈内动脉狭窄的血管内支架治疗是安全的。支架的选择与是否预扩尚待商榷。
Objective To evaluate the methodology of percutaneous transluminal stenting for stenosis of internal carotid artery (ICA). Methods 18 patients of ICA stenosis greater than 80% were included.All cases were under anticoagulative therapy perioperatively,and underwent cerebral vascular angiography and cervical Doppler sonography.Three kinds of different stents were used after advance angioplasty or not.To all the cases,“combined guiding” and “external carotid artery (ECA) supporting” techniques were used. Results All of the 18 cases underwent operation smoothly without any complications. All of the cases were successful on image post procedure.CBF was found to be normal or be increased on sonography.Symptoms disappeared in 15 cases and weakened on various degrees in 3 cases.On angiographic and sonographic followup in 3 to 24 months,no distortion of stents and restenosis was found,the blood flows were patent. Conclusion Percutaneous transluminal stenting was a safe therapeutic method for stenosis of internal carotid artery with correct perioperative therapy and operative method.Selection of stents and application of advance angioplasty were still to be discussed.
