摘要
目的 :探讨CT对腹腔内中空脏器穿孔的诊断价值。材料和方法 :CT检查24例无膈下游离气体的腹部中空脏器穿孔患者(23例手术 ,1例随访证实)。采用腹窗(窗宽300Hu ,窗位20Hu)及纵隔窗位(窗宽600Hu ,窗位 -30Hu)成像技术。结果 :CT确诊穿孔21例(87.5 %)。游离气体分布依次为前腹壁下、小网膜囊、后腹膜及肠系膜间等部位。21例中CT作出穿孔脏器(定位)诊断者13例(61.9 %)。病因(定性)诊断者12例(57.14 %)。结论 :常规腹部CT扫描结合纵隔窗位成像 。
Purpose:To evaluate the value of CT in diagnosis of the hollow viscera perforation.Materials and Methods:Twenty-four cases of hollow viscera perforation without infra-diaphragmatic free air (23 cases proved surgically and 1 cases proved by follow-up) were performed with CT.Both the abdominal window(window width,300Hu,window level 20Hu) and the mediastinal window(window width,600Hu,window level,-30Hu)were used.Results:Twenty-one cases(87.5%) were diagnosed as perforation with CT.The free air was distributed in anterior infra-abdominal wall,lesser sac,posterior peritoneum,and intra-mesentery subsequently.61.9% was localized and 57.14% was found the cause with CT.Conclusion:The conventional abdominal CT combined with mediastinal window can discover free air from the hollow viscera perforation and can be valuable in determining the location and causes.
