摘要 目的研究颅内外动脉支架植入术前后脑灌注CT成像的变化。方法回顾性分析50例接受颅内动脉支架置入术的脑缺血老年患者的临床资料。结果支架植入前颈内动脉狭窄侧脑血流容积(CBV)和对侧CBV之间的差异不显著(P>0.05);颈内动脉狭窄测的脑血流量(CBF)明显比对侧CBF低,平均通过时间(MTT)明显比对侧长(P<0.05);50例患者支架植入后,41例患者术后血流明显改善,9例患者没有明显的MTT恢复,分别占总数的82%和18%。术后对应供血区的rCBF明显比术前高,rMTT明显比术前短(P<0.05);所有患者的脑组织血流灌注均显著改善。结论脑灌注CT成像能够对颈内动脉狭窄患者的脑血学流改变进行敏感检测,在对颈内动脉支架植入术治疗缺血性脑卒中疗效的评价中发挥着至关重要的作用。
