超声诊断下肢交通静脉瓣膜功能不全的价值

Value of ultrasound in diagnosis of perforating venous insufficiency of the lower extremity

目的探讨彩色多普勒超声诊断下肢交通静脉瓣膜功能不全的临床价值。方法彩色多普勒超声检查35例大隐静脉曲张患者(观察组)和20例健康正常者(对照组)的下肢静脉。测定观察组交通静脉内径及反流时间,记录手术结果。结果两组交通静脉内径及反流时间有明显统计学差异(P<0.05);与手术结果对比(按交通静脉条数),观察组超声诊断准确率95.7%(110/115)、灵敏度97.1%(100/103)、特异度83.3%(10/12)、Youden指数80.4%、Kappa值0.776。结论彩色多普勒超声能准确定位瓣膜功能不全的交通静脉。

Objective To evaluate the clinical value of color Doppler ultrasound in the diagnosis of perforating venous insufficiency of the lower extremity. Methods The lower extremity veins of 35 cases with great saphenous vein varicose（group A） and 20 normal people（group 13） were examined by color Doppler ultrasound. The perforating venous insufficiency of the extremity in group A was diagnosed and located. The results were compared with the surgery results. Results The diameter and refux time of perforating venous were significantly different between two groups （P^O. 05）. After compared to the results of surgery in group A, total accordance rate, the sensitivity, specificity, Youden index, and Kappa value of ultrasound in the diagnosis of perforating venous insufficiency were 95.7%, 97.1%, 83.3 %, 80. 4% and 0. 776, respectively. Conclusion Color Doppler ultrasound can accurately locate the dilated and insufficient perforating venous of the lower extremity.
