Abstract    Acute mesenteric ischemia（AMI）is a rare and fatal surgical acute abdomen.The causes of the disease, it is divided into 4 categories: mesenteric artery embolism, mesenteric artery thrombosis, mesenteric venous thrombosis and non-occlusive mesenteric ischemia. The early onset of AMI is very insidious, often with the characteristics of "severe symptoms and mild signs", which makes the early diagnosis of the disease very difficult. In the past, many articles have explored what laboratory indicators can effectively predict whether patients with acute abdomen are AMI, but the final results found that the current clinically commonly used laboratory indicators can not achieve this task. The accuracy of early mesenteric vascular CTA in the diagnosis of AMI is very high, but no study has concluded that these indicators directly indicate transmural necrosis of the intestine. It is difficult to diagnose and treat the disease early. As a result, the disease often causes transmural necrosis of the small intestine, and then develops into severe abdominal infection, resulting in adverse treatment consequences. How to accurately judge the existence of transmural necrosis of the small intestine has gradually become the focus of scholars' research.

Key words: acute mesenteric ischemia, transmural intestinal necrosis
