摘要:
目的利用氙气CT(XeCT)技术分析颈动脉重度狭窄的血流动力学特点,并以此评价支架成形术的疗效。方法对13例颈动脉重度狭窄进行支架成形治疗,并利用XeCT进行血流定量评价。患者术前及术后1周分别接受XeCT检查,根据病变侧大脑皮层的脑血流值分为正常区、轻度缺血区、可逆性缺血区和梗死区,并按缺血面积大小作术前、术后对比。结果所有患者术前局部脑血流量均有不同程度降低,以大脑中动脉分布区最为显著;术后脑血流值有显著改善,轻度缺血区面积由32.63%变为14.22%,可逆性缺血区面积由13.54%变为8.38%,正常区域面积由47.51%变为71.13%,而梗死面积无显著变化。结论颈动脉重度狭窄时,脑组织存在易导致脑梗死的缺血区域,支架成形术治疗可明显改善患者的血流动力学障碍,其疗效可以通过定量的脑血流测定得到客观和准确的评价。
