彩色多普勒超声对腹直肌裂伤合并血肿患儿的诊断价值分析

The diagnosis value of color doppler uitrasound to the formation of rectus abdominis muscle laceration hematoma after strenuous exercise in chil-dren

目的：探讨彩色多普勒超声诊断腹直肌裂伤合并血肿患儿的临床价值。方法选取2009年1月～2014年1月在我院就诊的腹直肌鞘内血肿患儿29例，对所有患儿在治疗前行腹直肌超声检查，得出患儿腹直肌的二维及彩色多普勒图像，并对图像结果进行对比分析。结果研究组的腹直肌鞘内血肿检出率明显高于对照组，误诊和漏诊的比例明显低于对照组，平均血肿大小明显大于对照组，差异均具有统计学意义（P〈0.05）；研究组的超声声像图在形状规则性、边界清晰度、敏感性、特异性、准确度均明显高于对照组，差异均具有统计学意义（P〈0.05）。结论儿童在剧烈运动后肌肉间供应血管易发生破裂，形成腹直肌鞘内血肿，而彩色多普勒超声相比于二维超声更适合诊断剧烈运动后患儿发生的腹直肌鞘血肿。

Objective To analyze the diagnosis value of Color Doppler Uitrasound for the formation of rectus abdominis muscle laceration hematoma after strenuous exercise in children. Methods 29 cases of children patients with rectus sheath hematoma were selected as the research object from January 2009 to January 2014 in our hospital, all patients received rectus abdominal ultrasonography before treatment,got the two-dimensional ultrasonic images and color Doppler image of patients of abdominal rectus. Results Rectus sheath hematoma in the detection rate of the study group was significantly higher than the control group, the misdiagnosis and missed diagnosis ratio were significantly lower than the control group, the average size of hematoma was significantly higher than the control group, the difference was statistically significant（P〈0.05）; Ultrasonographic study group in regular shape, boundary definition, sensitivity, specificity, accuracy were significantly higher than that of control group,al the differences were statistically significant（P〈0.05）. Conclusion Children＆#39;s blood vessels that supply the prone to rupture after strenuous exercise muscle, the rectus sheath hematoma formation, and color Doppler ultrasound compared with two-dimensional ultrasound in diagno-sis is more suitable to occur after strenuous exercise rectus sheath hematoma.
