彩色多普勒在脑梗塞病中的临床应用

了解彩色多普勒对脑梗塞病的应用价值。方法：对４２例脑梗塞患者和３６例健康人的颈动脉颅外段进行二维超声切面显像与彩色多普勒检测。了解颈动脉粥样斑块发生情况，测定颈动脉收缩期血流峰值，舒张期血流峰值，和阻力指数。结论彩色多普勒能清楚显示脑梗颈动脉病变情况，有效评价其血流动力学状，具有重要的临床应用价值。

Clinical Application of Color Doppler Ultrasonography in Cerebral Infarction

To evaluate the application of color doppler ultrasonography in cerebral infarction. Methods: 42 patients with cerebral infarction and 36 health volunteers as control were subjected to this study. Echo - planar imaging and color doppler ultrasonography were performed on the extracranial segment of carotid artery, and the development of carotid atherosclerosis plaque, carotid peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) were determined. Results: Of the 42 patients with cerebral infarction, 26 cases had carotid atherosclerosis plaque at the same side of infarction. Compared with the health control, patients with cerebral infarction had lower PSV and EDV, particularly for EDV in internal and common carotid arteries. Conclusion: The color doppler ultrasonography is capable of clearly detecting the carotid pathological alterations and hemodynimic status in patients with cerebral infarction. It may have important clinical application in this disease.
