Abstract: Objective: To sum up the clinical data and CT features of the acute mesenteric ischemia（AMI） and explore the value of multi-slice spiral computed tomography（MSCT） in diagnosis of AMI. Methods: CT features and clinical data of 54 cases with clinical or surgically proven AMI were retrospectively analysed,including the onset time, main symptoms, signs and the indexes of laboratory examination, and the abnormal MSCT findings were analyzed. Results: All 54 cases presented with initial symptom of non-specific abdominal pain, including superior mesenteric venous thrombosis（SMVT,n=38）, superior mesenteric artery embolization（SMAE,n=12）, superior mesenteric artery thrombosis（SMAT,n=4）. The direct sign of AMI in MSCT images was filling defect in mesenteric vessels（n=43）. The indirect signs included thickening of bowel wall（n=35）, target sign（n=16）, bowel lumen dilatation（n=20）, strand sign（n=22）, pneumatosis of bowel wall（n=13）, thin bowel wall（n=12） and ascites（n=34）. Conclusion: AMI lacks specific clinical manifestations, the degree and extension of mesenteric ischemia can be accurately diagnosed by MSCT scan, which had an important clinical value for guiding the treatment of AMI.
