高频超声和彩色多普勒血流显像诊断腹股沟斜疝

目的探讨高频超声和彩色多普勒血流显像（CDFI）在腹股沟斜疝诊断中的价值。方法对79例高频彩超检查诊断腹股沟斜疝且经手术病理证实的患者进行回顾性分析。结果腹股沟斜疝表现为腹股沟区腹壁层内见疝囊,其近端通过疝囊颈（内环口）与腹腔相通,远端为边界清晰的盲端。高频彩超显示疝内容物为肠管时可见肠管管壁特点、气体回声、肠腔内容物,肠壁有多条彩色血流;内容物为大网膜时为簇状杂乱回声团或筛网状回声团,伴斑点状彩色血流。嵌顿疝及绞窄疝内的彩色血流有不同程度改变。腹壁下动脉在疝囊的后方、疝囊颈的内侧。精索紧贴疝囊的后壁。结论高频超声和CDFI能显示腹股沟斜疝内容物性质,指导选择手术时机和方法;CDFI对鉴别诊断、判断内容物损害程度及预后评估有重要价值。

High frequency ultrasound and color Doppler flow imaging in diagnosis of oblique inguinal hernia

Objective To explore the application value of high frequency ultrasound and CDFI in diagnosis of oblique inguinal hernia.Methods Seventy-nine patients with oblique inguinal hernia who were examined and diagnosed by high frequency ultrasound and CDFI were retrospectively analyzed.All these cases were verified by pathology or operations.Results Hernia sac could be displayed in inguinal region,with the upper part extending to abdominal cavity and the smooth ending.High frequency color Doppler ultrasound showed...
