摘要
经颅多谱勒仪测定３１ 例老年人脑梗塞康复期患者及２８ 例健康老年人大脑中动脉（ ＭＣＡ） 血流动力学参数，并对２２ 例ＭＣＡ 血流速减低者进行体外反搏治疗。结果发现：老年人脑梗塞患者 ＭＣＡ 的Ｖｐ ，Ｖｍ 低于健康老年人（ Ｐ ＜ ０ ．０１） ；两侧ＭＣＡ 的ＤＶｐ ，ＤＶｍ 高于健康老年人（ Ｐ ＜ ０ ．０１） ，血流速不对称性高于健康老年人（ Ｐ ＜ ０ ．０１） ；体外反搏治疗后 ＭＣＡ 的Ｖｐ ，Ｖｍ 增高（ Ｐ ＜ ０ ．０１） ，ＤＶｐ ，ＤＶｍ降低（ Ｐ ＜ ０ ．０１） ，血流速不对称性缩小（ Ｐ ＜ ０ ．０１） ；血流动力学疗效达８１－８ ％ 。表明体外反搏治疗可改善患者脑血流动力学的状况。
Hemodynamic parameters of middle cerebral artery(MCA) were measured with Transcranial Doppler(TCD) in 31 elderly patients with brain infarction during convalescene and 28 healthy elderly controls. Twenty two elderly patients with brain infarction and cerebral hemodynamic impaired were treated by External Counterpulsation(ECP). The results showed that the Vp and Vm of MCA in patients were significantly lower than that in the healthy controls(P<0.001), the DVp, DVm and asymmetry of MCA in patients were greater than that in the healthy elderly(P<0.001, P<0.005). The Vp and Vm of MCA in patients after ECP were significantly higher than before(P<0.001). The DVp, DVm and asymmetry of MCA in patients ofter ECP were significantly lower than before(P<0.001, P<0.005). The hemodynamic therapeutic effect is 81.8%.
