Evaluation of color Doppler flow image in malfunction of lower extremity perforator vein

目的探讨彩色多普勒超声在检测下肢交通支静脉功能不全中的应用价值。方法应用彩色超声多普勒对60条肢体进行检查，并对照顺行下肢静脉造影结果，研究其诊断可行性。结果超声共检出功能不全的交通支静脉212条，以下肢顺行静脉造影为金标准，超声检查下肢交通支静脉功能不全的敏感性为91．1％，特异性为85．8％，准确性为91．9％。结论彩色超声多普勒是一种简便而无创性的检查下肢交通支静脉功能不全的方法。

Objective To evaluate the diagnostic role of the color Doppler flow image（CDFI） in malfunction of lower extremity perforator vein. Methods Using color Doppler flow image method,60 lower extremities were examined, and compared with the results of the lower extremity vein angiography, then assessed the accuracy of CDFI method. Results 212 lower extremity perforator veins of malfunction were found,and compared with results of the lower extremity vein angiography, the sensitivity of CDFI method is 91.1%, the specificity of CDFI method is 85.8% ,the accuracy of CDFI method is 91.9%. Conclusion CDFI is useful for the diagnosis of malfunction of lower extremity perforator vein and can offer reliable bases to clinical operation.
