摘要
目的探讨彩色多普勒超声在下肢大隐静脉曲张患者诊断中的应用价值。方法采用彩色多普勒超声观察79例96条确诊为下肢静脉曲折患者的深静脉管壁及瓣膜回声、管腔形态、反流时间、反流速度及频谱多普勒显像情况,并与静脉X-线造影对比分析。结果彩色多普勒超声检查与造影对比,深静脉完全正常诊断准确性为98.33%,单纯深静脉瓣功能不全诊断准确性为91.67%,深静脉血栓后遗症诊断准确性为100.00%,动脉-静脉瘘诊断准确性为100.00%。对60条大隐静脉行剥离手术,术后未出现下肢肿胀,复查彩超亦未见深静脉返流现象。96条患肢均可测及不同部位、不同程度的静脉反流。其中股浅静脉瓣反流时间最长,为(5.92±1.83)s,反流速度(50.28±19.48)cm/s,小腿交通静脉反流时间最短,为(2.37±1.92)s,反流速度(27.92±17.28)cm/s。结论彩色多普勒超声对评价下肢大隐静脉曲张患者的深静脉结构及血流状态有十分重要的临床价值。
Objective To evaluate the value of color Doppler ultrasonography in the diagnosis of varicose veins of lower extremities.Methods The color Doppler ultrasound was used to observe 79 patients with a diagnosis of 96 deep vein of lower limb venous tortuosity on pipe wall,valve echo,shape of the lumen,anti-flow,counter flow velocity and spectrum Doppler imaging;and all characters were compared with vein X-ray.Results With a contrast analysis,completely normal diagnostic accuracy of color Doppler ultrasonography was 98.33% on deep vein.Diagnostic accuracy was 91.67% on dysfunction for alone venous valve,100.00% on sequela of deep vein thrombosis,also 100.00% on arterial-venous fistula.The sonographic appearance of 60 deep great saphenous veins was similar to that of the control group,on the vein stripping surgery,no postoperative lower limb swelling,no deep venous reflux phenomenon by review of ultrasound.But 96 affected limbs could be measured on different parts,different levels of venous reflux.The reflux time of superficial femoral vein valve was the longest,which was s（5.92±1.83）,reflux rate（50.28±19.48）cm/s,and lower leg traffic vein reflux time was the shortest（2.37±1.92）s,reflux rate（27.92±17.28）cm/s.Conclusion Color Doppler ultrasound plays a very important clinical action in evaluation of lower extremity varicosis of great saphenous vein in patients with deep vein structure and blood flow.
