摘要
目的探讨高频彩色多普勒超声在下肢小腿肌间静脉血栓形成中的应用价值。方法回顾性分析临床确诊的46例(53条)小腿肌间静脉丛血栓形成患者的声像图表现并与临床随访结果进行对比分析。结果 46例(53条)小腿肌间静脉血栓,超声诊断正确41例(47)条,误诊5例(6条),诊断准确率89%。所有患者临床均进行溶栓及抗凝治疗,治疗后2周、1月、3月复查超声,血流完全或部分再通。超声二维图像示:小腿肌间静脉丛内径不规则增宽,管壁增厚,内膜不光滑,其内见不均质低回声或无回声充填,长轴切面呈长条形,短轴切面呈类圆形,管腔不能压瘪;彩色多普勒超声示:病变部位管腔内未探及明显血流信号。结论本研究表明高频彩色多普勒超声是诊断小腿肌间静脉丛血栓的首选方法,可以显示血栓的位置、管腔阻塞程度、血流状态,同时对治疗效果可以进行动态评估。
Objective This paper aim to study the application value of high-frequency color Doppler ultrasound to diagnose calf muscular venous thrombosis.Methods The sonographic features of46patients with53CMVT were analyzed retrospectively and compared with the outcome of clinical followup.Results41cases with47CMVT were diagnosed by high-frequency color Doppler ultrasound and5cases with6CMVT were missed diagnosis,the accuracy rate was89%.All patients prescribed thrombolysis and anticoagulation therapy,after treatments,high-frequency color Doppler ultrasound for0.5,3,6months revealed partial or complete recanalization.The two-dimension sonographic features showed that the diameter of calf muscular vein irregularly broadening,the walls of vein thickened,the vein displayed no smooth intima with long strip shape in the longitudinal view and the round shape in the transversal view,and the lumen was filled with the not homogeneous low echo or no echo,pathological changes of color Doppler flow imaging:in the lumen,and no obvious blood flow signal.Conclusion Because highfrequency color Doppler ultrasound could clearly be showed the position of thrombus,the degree of obstruction,the blood flow,and the therapeutic effect,so it is the first choice in the diagnosis of the calf muscular venous thrombosis.
