目的：探讨彩色多普勒超声对小腿肌间静脉丛血栓和肌间血肿的鉴别诊断要点。方法回顾性分析临床确诊的小腿肌间静脉丛血栓54例（血栓组)和小腿肌间血肿24例（血肿组)的二维超声和彩色多普勒血流显像（CDFI)特点,总结超声鉴别诊断要点。结果两组二维超声和 CDFI 影像学表现相似。血栓组36例、血肿组12例均呈实性低回声；血栓组37例、血肿组8例形态均呈窄条形；血栓组30例、血肿组24例局部无血流信号；血栓组40例、血肿组16例压迫试验阳性。血栓组病变均沿血管走行,血肿组病变则多呈局限性；血栓组两端与静脉相连续,血肿组则无此征象,仅10例病变对邻近静脉产生挤压。结论小腿肌间静脉丛血栓和小腿肌间血肿超声声像图容易混淆,需仔细鉴别,CDFI 可作为重要的鉴别诊断手段。

Objective To investigate the key points of color Doppler flow imaging (CDFI) in differential diagnosis of calf muscular venous thrombosis and intramuscular hematoma in human legs. Methods The imaging characteristics of two di-mensional ultrasonography and CDFI findings in 54 patients with calf muscular venous thrombosis in leg (thrombosis group) and 24 patients with intramuscular hematoma in legs (hematoma group) were retrospectively analyzed, and key points of ultra-sonic differential diagnosis were summarized. Results The imaging characteristics of the two dimensional ultrasonography and CDFI findings in the two groups were similar. The hypoechoic was found in 36 patients in thrombosis group and 12 patients in hematoma group; strip-shaped echo was found in 37 patients in thrombosis group and 8 patients in hematoma group; no local blood flow signal was found in 30 patients in thrombosis group and 24 patients in hematoma group; positive results of compres-sion test were found in 40 patients in thrombosis group and 16 patients in hematoma group. Thrombosis extended along the blood vessels in thrombosis group, while hematomas in hematomas group was mainly localized; the end of thrombosis connect-ed with veins while hematoma did not show the sign, in which only 10 patients in hematoma group compressed nearby veins. Conclusion Ultrasound imagings of calf muscular venous thrombosis and intramuscular hematoma in legs may be confused, and CDFI can be used as an important method for differential diagnosis.
