彩色多普勒超声在下肢静脉曲张交通静脉检测中的应用

目的探讨彩色多普勒超声（color Doppler ultrasound，CDU）在下肢静脉曲张中交通静脉功能不全的检查技巧和诊断方法。方法应用Logiq700彩色多普勒超声仪对33例下肢静脉曲张患者进行术前下肢静脉CDU常规检查，探测交通静脉的发生部位、范围、内径及瓣膜功能情况，标记其在体表的部位，并与手术结果比较。结果33例下肢静脉曲张患者中共发现151条交通静脉功能不全，主要发生部位位于小腿浅静脉区域（82％）和大腿部位（18％）。CDU所见的交通静脉均得到手术证实，与手术结果相比，CDU显示率为83％。结论CDU能显示大部分下肢静脉曲张中的交通静脉，是一种能准确诊断下肢交通静脉功能不全简单易行的无创性检查技术。

Color Doppler ultrasound in perforating veins of lower extremity with varicosity

Objective To investigate the scan skills and diagnostic methods in assessment of perforating veins of lower extremity with varicosity using color Doppler ultrasound （CDU）. Methods Thirty-three patients with varicosity of lower extremity were routinely detected by Logiq 700 ultrasound system with the 5 - 10MHz linear transducer before operation. The perforating veins were completely evaluated, including location, extension, size and valvula function. Results One hundred and fifty-one incompetent perforating veins were found in 33 patients. Most of the perforating veins were located in calf （82%） and only 18% in thigh. All of the incompetent perforating veins found in CDU were confirmed in operation. Compared with the operation, 83% perforating veins were demonstrated by CDU. Conclusion CDU can demonstrated most of incompetent perforating veins of lower extremity with varicosity. It is a simple and non-invasive technique for accurate diagnosis of incompetent perforating veins of lower extremity with varicosity.
