摘要
目的 :探讨脑梗塞急性期经颅多普勒超声 (TCD)的平均血流速度 (Vm)的变化及其在不同治疗期TCD检查的临床意义。方法 :49例患者入院前后行头颅CT和 /或MRI检查证实为大脑中动脉 (MCA)区脑梗塞者 ,入院后 1周内、第 2周及第 3周行TCD检查。结果 :①MCA区脑梗塞后病侧MCAVm明显低于对照组 (P <0 .0 5 )和病灶对侧 (P <0 .0 1) ;双侧大脑前动脉 (ACA)Vm高于对照组 (P <0 .0 5 ) ;病侧MCAVm >ACAVm的生理关系消失。②MCA区梗塞中主干及深穿支梗塞MCAVm下降明显(P <0 .0 5 )。③TCD间断观察揭示MCAVm随有效治疗而增加。结论 :TCDVm的变化有助于判断脑梗塞的部位、临床治疗选择和疗效判断。
Objective:To investigate the changes of t he mean velocity(Vm) by transcranial doppler ultrasound(TCD) in the middle cer ebral artery(MCA) area with acute ischemic stroke patients,and to evaluate the s ignificance of TCD findings in the different course of stroke. Methods:Fourty nine stroke patients,proven by CT and/or MRI scan in the MCA area,got TCD serial examination at 1,2,3 weeks after admission.Results:①The Vm in ipsilateral MCA was significantly lo wer than that of the contralateral(P<0.01) and the control group(P<0.0 5); and the Vm in bilateral anterior cerebral artery(ACA) in ischemic stroke was significantly higher than that of the control(P<0.05).The physiological ph enomenon of MCA Vm>ACA Vm disappeared.②The MCA Vm of the stem and the penetrat ing arteries occlusion in the MCA area reduced significantly.③The MCA Vm was in creasing with the effective therapy.Conclusion:The c hanges of Vm may be of help to find the area of ischemic stroke,to select the c linical therapeutic method and to evaluate the therapeutic effects.
