Stroke:TCD 诊断再通治疗后的无复流现象

2018-11-26 杨中华 脑血管病及重症文献导读

尽管成功再通,四分之一的卒中患者存在组织灌注受损,这对临床预后产生不良影响。来自动物组织学的研究显示,短暂闭塞MCA 可见到微血管梗阻,这是无复流现象的机制。截止到目前为止,尚缺乏临床证据。

尽管成功再通,四分之一的卒中患者存在组织灌注受损,这对临床预后产生不良影响。来自动物组织学的研究显示,短暂闭塞MCA 可见到微血管梗阻,这是无复流现象的机制。截止到目前为止,尚缺乏临床证据。

Gosling 搏动指数(pulsatility index,PI)和Pourcelot 阻力指数(resistance index,RI)是 TCD 的常用参数,是脑血管阻力的指数。

2018年10月来自澳大利亚的Felix C. Ng等在 Stroke 上公布了他们的研究结果,目的在于探讨 TCD 是否可以检测再通后微血管的无复流现象。

从2013年1月到2017年12月连续的急性 MCA 闭塞后机械性再通的患者53例,发病6h 内达到 TICI IIb/III 再通,并且在3天内进行了 TCD 评价,计算PI([PSV?EDV]/MFV)和 RI([PSV?EDV]/PSV)。MFV(Mean-flow velocity),平均血流速度;PSV(peak-systolic velocity),峰收缩期速度;EDV(end-diastolic velocity),舒张末期速度。把这些患者与53例年龄/性别匹配的对照组患者相比。

在53例患者中,内部比较(interside comparison)发现MCA-PI不对称性增加(27.9% vs 4.9%;P = 0.007)的可能性更大,症状半球的 MCA-PI异常升高超过正常范围的可能性更大(46.7% vs 22%;P = 0.016)。MCA-PI 升高与更少的出血性梗死相关(9.5% vs 45.8%,P = 0.009),但是功能预后更差(mRS<=1,18.2% vs 58.1%,P = 0.035)。

最终作者认为采用 TCD PI 监测发现成功再痛后缺血区域微血管阻力增加非常常见,这可能是诊断无复流现象的一种有效可行、临床相关的标志物。
