摘　　要：目的　评估多功能血管检测仪 (PVL)的多普勒超声血流波形分析或 (和 )节段性动脉压诊断下肢动脉缺血性疾病的价值 .方法　用 PVL 两种检查方法诊断的动脉硬化性闭塞症 (ASO) 2 2例 (31肢 ) ,血栓闭塞性脉管炎 (TAO) 15例 (2 0肢 ) ,共 37例 (5 1条肢体 )与动脉造影对照 .结果　以动脉造影为金标准 ,多普勒超声血流波形分析对下肢动脉缺血性疾病的定位符合率为 94 .0 % ,有 2肢股动脉病变因多普勒血流波形大致正常而定位下移 ,有 1肢动脉段病变其股浅动脉即呈异常单相波而定位上移 .节段性动脉压对下肢动脉缺血性疾病的定位符合率为 94 .1% ,有 2肢髂动脉、1肢股动脉其病变部位血压指数 >1.0 ,相邻压差 >4 k Pa而定位下移 ;1肢股动脉病变其血压指数和相邻压差均正常而诊断定位下移 ;1肢胫后动脉病变因踝 /肱指数 (A/ BI) <1.0 ,膝下与膝上动脉压差 >4 k Pa,诊断定位上移 .根据多普勒超声血流波形分析和节段性动脉压任一检测方式的异常即诊断该部位存在狭窄或闭塞的标准 ,全组 PVL 的诊断符合率 96 .1% .结论　 PVL多普勒超声血流波形分析和节段性动脉压检查与临床资料结合诊断下肢动脉缺血性疾病有重要意义 ,且无创伤、无痛苦 .AIM To evaluate the methods of Doppler ultra sound blood flow waveform analysis and/or segmental pressure of personal vascular laboratory (PVL) on the diagnosis of the lower extremity arterial ischemic disease. METHODS Twenty two cases (31 limbs) of suspected arteriosclerosis obliterans (ASO) and 15 cases (20 limbs) of suspected thromboangiitis obliterans (TAO) diagnosed by PVL were compared with the results of arteriography. RESULTS Compared with the golden standard of arteriography. The accuracy rate of the ultrasonic Doppler blood flow waveform analysis in the locational diagnosis of lower extremity arterial disease was 94.1 percent, and the accuracy rate of the segmental pressure was 90.2 percent, respectively. CONCLUSION Combined with clinical data, the analysis of blood flow waveform and segmental pressure were of significance in the diagnosis of lower extremity arterial ischemic disease. The method is non invasive and practical.
