简介:摘要目的探讨B超在外伤性肝破裂诊断中的临床应用价值。方法选择我院2011年-2013年收治的31例外伤性肝破裂患者作为研究对象,分析31例患者入院检查早期B超检查影像学图像特征,并观察B超检查结果与手术探查结果的符合率。结果31例患者经B超检查,9例患者为真性肝破裂,13例为中央型肝破裂,7例患者为包膜下肝破裂,其中14例为肝实质离断伤,8例为挫裂伤,5例为包膜下血肿,2例为肝癌性破裂,与手术探查诊断结果的符合率为93.5%(29/31);肝实质破裂B超影像学图像表现为肝体增大,内部呈低回声或无回声,肝体轮廓不规则,包膜表现为不连贯中断,包膜下血肿B超影像学图像表现为包膜回声低或呈漂移状,在肝实质和包膜间回声不规则。结论B超诊断外伤性肝破裂的确诊率高,且具有可重复、简便、可动态观察及费用低等优势,在外伤性肝破裂的临床诊断中具有重要的应用价值。
