目的评价脑保护装置下老年重度颈动脉狭窄患者颈动脉支架成形术的有效性及安全性。方法选择年龄≥70岁的重度症状性颈动脉狭窄患者43例,均行颈动脉支架成形术,术中均应用脑保护装置,观察术后狭窄改善情况,围术期并发症的发生情况以及回收的脑保护装置内脱落栓子情况,对患者随访1年。结果在43例患者中,脑保护装置及颈动脉支架均放置到位,术后残余狭窄率均<30%,患者颈动脉平均狭窄程度从(82.8±6.5)%降低至(12.4±5.9)%,支架置入手术前后比较,差异有统计学意义(P<0.05)。回收的脑保护装置中,发现27个有脱落的组织碎片,患者术后缺血相关症状均有明显改善,围术期所有患者均未出现症状性脑卒中,无手术相关死亡事件发生,1年随访无缺血性脑血管事件发生,颈动脉超声复查未见支架内发生再狭窄。结论脑保护装置下,对老年重度颈内动脉狭窄患者行颈动脉支架成形术安全、有效。
