彩色多普勒超声对早期小腿肌间静脉丛血栓的诊断及漏诊分析

目的探讨彩色多普勒超声对小腿肌间静脉丛血栓的诊断价值及漏诊原因。方法回顾性分析41例临床确诊为小腿肌间静脉丛血栓患者的二维超声与彩色多普勒超声检查资料及超声随访情况。结果 41例临床确诊为小腿肌间静脉丛血栓的患者中,彩色多普勒超声确诊39例,超声检查的早期确诊率在95%以上,其中单肢病变33例,包括右侧12例,左侧21例,双侧病变3例;合并同侧主干血栓3例;漏诊2例。经过临床溶栓治疗后患者临床症状减轻或消失,经彩色多普勒检查证实血栓部分消失或完全消失。结论彩色多普勒超声可以显示血栓的形态、类型、位置、管腔阻塞情况、血流状态,并且可以评价其严重程度,对治疗效果可以进行动态评估,是一种无创、快捷、准确的可重复检查的诊断方法。

Color Doppler ultrasound in early diagnosis and misdiagnosis of calf muscle venous plexus thrombosis

Objective The causes of diagnosis and misdiagnosis for the calf muscle venous plexus thrombosis by Doppler ultrasound were to discuss. Methods A total of 41 cases diagnosed as calf muscle venous plexus thrombosis between the two-dimensional ultrasound, color Doppler ultrasound and ultrasound follow-up information were retrospectively analysed. Results Of all 41 cases diagnosed between the calf muscle venous plexus thrombosis, 39 cases were diagnosed by color doppler ultrasound with an early diagnosis rate of 95% including one limb lesion in 36 cases, the right side in 12 cases, 21 left cases, three cases of ipsilateral trunk thrombosis, bilateral lesions in 3 cases; and missed in 2 cases. After thrombolytic therapy, the patients with clinical symptoms were improved or disappeared, some of thrombosis by color Doppler validation disappeared or completely disappeared. Conclusion Color Doppler ultrasound can show blood clots form, type, location, lumen obstruction, blood flow, and can dynamically evaluate the severity of the treatment effect, which is a non-invasive, fast, accurate and repeatable diagnostic method.
