目的用TCD检测周围性、中枢性眩晕,有助于临床诊断和治疗。方法对200例眩晕患者进行了检测分析。结果周围性眩晕患者TCD异常,主要是血管紧张度增高所致的血管流速增快;而中枢性眩晕患者是脑供血不足所致的血流速度减慢。结论由于TCD为无创性检测手段,简便易行,重复性好,所以应用该方法对眩晕患者进行检测,可以明确其病因,有助于临床诊断和治疗方法的选择。 Objective TCD detection of peripheral, central vertigo, contribute to clinical diagnosis and treatment. Methods 200 cases of vertigo patients were analyzed. Results TCD in patients with peripheral vertigo was abnormal, which was mainly due to the increase of vascular velocity caused by the increase of vascular tone. However, the central blood flow was slowed down in patients with central vertigo. Conclusion Because TCD is a noninvasive method, it is simple, easy to operate and has good repeatability. Therefore, this method can detect the etiology of vertigo patients and help to choose the method of clinical diagnosis and treatment.
