超声波诊断创伤性腹膜后血肿探讨

目的研究探讨超声波诊断创伤性腹膜后血肿的临床应用价值。方法选取该院2009年—2014年间收治的创伤性腹膜后血肿的患者67例作为研究对象,分别采用超声波扫描和CT扫描的方法对患者进行诊断,回顾性分析患者的影像学特征,以手术病理检查结果作为判断依据,计算不同其诊断的准确性。结果以手术病理学检查结果为标准,超声诊断确诊为腹膜后血肿45例,诊断准确率为67.2%;CT诊断确诊54例,诊断准确率为80.6%,CT诊断的准确性略高于超声,但差异无统计学意义（χ^2=3.31,P=0.077）。超声、CT联合诊断的准确率为100.0%。结论超声波检查可以对创伤性腹膜后血肿的患者进行动态观察,了解患者的血肿变化,对于腹膜后血肿的临床治疗具有一定的价值,能和CT联合应用实现诊断准确率的提高。

Investigation on the Ultrasonic Diagnosis of Traumatic Retroperitoneal Hematoma

Objective To study the clinical application value of ultrasound in the diagnosis of traumatic retroperitoneal hematoma.Methods 67 cases with traumatic retroperitoneal hematoma admitted in our hospital from 2009 to 2014 were selected as the subjects,and diagnosed by ultrasonic scanning and CT scanning,respectively.The imaging characteristics of the patients were analyzed,and the results of operation pathological examination were set as the basis for judging the accuracy of different diagnostic methods.Results The results of operation pathological examination were set as the standard for judging the accuracy of different diagnostic methods,45 cases with traumatic retroperitoneal hematoma were confirmedly diagnosed by ultrasound,the diagnostic accuracy rate was 67.2%;54 cases were confirmedly diagnosed by CT,the diagnostic accuracy rate was 80.6%.The diagnostic accuracy rate of CT was slightly higher than that of ultrasound but without statistically significant difference（χ2=3.31,P=0.077）.The diagnostic accuracy rate of ultrasound combined with CT was 100.0%.Conclusion By ultrasound,the patients with traumatic retroperitoneal hematoma can be observed dynamically,the changes of hematoma can be understood.Therefore,ultrasound has certain value in the clinical treatment of retroperitoneal hematoma,and the diagnostic accuracy rate can be improved by the combination of it and CT.
