【摘要】 目的分析少见腹膜后闭合性损伤的CT表现,提高其诊断水平。方法回顾性分析13例经手术或临床证实的少见腹膜后损伤的CT表现。结果肾上腺血肿11例,伴有肾动脉闭塞2例,表现为肾动脉突然截断,以及"边缘征"。血肿表现为圆形、类圆形或团块状高密度影,并有肾上腺周围组织损伤。胰腺断裂2例,表现为垂直于胰腺长轴的低密度影。结论CT是诊断腹膜后闭合性损伤的重要方法。更多还原

【Abstract】 Objective To analyse CT diagnosis of unusual closed retroperitoneal trauma so that to improve its diagnostic accuracy.Methods CT features of unusual closed retroperitoneal trauma confirmed by clinical data and surgery in 13 cases were analyzed.Results There were adrenal hematomas in 11 cases,among them,2 cases accompanied with renal arterial occlusion,appeared as renal arterial ruptured suddenly and "interface sign".The hematomas appeared as round,similar round or mass hyperdense shadows and in combination with periadrenal tissue injury;pancreatic rupture in 2 cases,appeared as linear area of low attenuation inside pancreas.Conclusion CT scan is an effective modality for diagnosing the unusual closed retroperitoneal trauma.Correct CT diagnosis is very important for the effective surgical treatment as well as reduction of severe complications and mortality of unusual closed retroperitoneal trauma.更多还原
