急性肠缺血病情凶险,病死率高,易误诊.应用多排螺旋CT及CT血管造影检查快速准确诊断急性肠缺血及其病因,具有重要临床意义.回顾性分析2005年1月至2013年6月西安市西电集团医院收治的31例急性肠缺血患者的临床资料.肠系膜动静脉狭窄闭塞,病变肠壁强化减弱或消失是急性肠缺血的直接CT征象,肠壁增厚是急性肠缺血最典型的间接CT征象,肠管扩张或萎陷也是急性肠缺血常见的间接CT征象,肠系膜脂肪水肿浑浊也较多见,肠壁积气、静脉积气是肠梗死的可靠CT征象.动脉栓塞或血栓形成、静脉血栓形成、动脉粥样硬化、血管炎、大动脉炎、绞窄性肠梗阻、肠系膜上动脉夹层均是急性肠缺血的可能病因.

Acute mesenteric ischemia (AMI) is a lifethreatening disease,with high mortality rate and is easily misdiagnosed.Rapid and acute detection of the AMI and its primary diseases by multi-slice computed tomography (MSCT) and computed tomography angiography (CTA) is of great significance.The clinical data of 31 patients with AMI who were admitted to the Xidian Group Hospital from January 2005 to June 2013 were retrospectively analyzed.Stenosis or occlusion of the mesenteric blood vessels,diminished or absent enhancement of the bowel wall are the direct signs of CT,thickening of the bowel wall is the most typical indirect sign of CT.Dilatation or collapse of the bowel lumen and swelling of the mesenterium are the common CT signs.Pneumatosis intestinalis and gas in the portomesenteric vein are reliable CT signs of the Intestinal Infarction.Artery and venous embolism,atherosclerosis,vasculitis,aortitis,strangulated intestinal obstruction and superior mesenteric artery dissection are the possible causes of AMI.
