目的通过对下肢静脉血栓超声患者的超声资料进行回顾性分析,总结分析误诊漏诊的原因方法对70例临床怀疑为下肢静脉血栓的病人进行常规静脉彩超检查,对确诊为下肢静脉血栓的患者再行CT静脉造影检查,而后对两者诊断结果进行对照分析。结果 70例临床疑似为下肢静脉血栓病人中,确诊率为57.1%（40/70）,超声误诊率32%（8/25）。结论超声检查无创伤、重复性高,可准确诊断下肢静脉血栓形成。Objective The data of patients with lower extremity venous thrombosis were analyzed retrospectively, and the causes of misdiagnosis and missed diagnosis were summarized. Methods 70 patients with clinical suspicion of lower extremity venous thrombosis were treated by routine venous color Doppler ultrasonography, and the venous thrombosis was diagnosed by CT venous angiography.Results Among 700 patients with clinical suspicion of lower extremity venous thrombosis, the accuracy rate was 57.1%, and the misdiagnosis rate was 32%. Conclusion Because ultrasound examination has high repeatability and no trauma, it can be used to diagnose exactly the lower extremity venous thrombosis.
