Analysis for abdomen CT characteristics of patients with ischemic bowel disease

Objective To investigate the abdomen CT characteristics of patients with ischemic bowel disease (ICBD). Methods CT imaging data of ICBD patients from January 2008 to December 2013 in the Chinese PLA General Hospital were retrospectively analyzed to find CT imaging features in intestinal lesions associated with ICBD death. Results In CT imaging analysis, 151 patients including acute superior mesenteric artery thromboembolism (ASMATE, n=51), acute superior mesenteric vein thrombosis (ASMVT, n=53), non-occlusive mesenteric ischemia (NOMI, n=8), chronic mesenteric ischemia (CMI, n=10) and ischemic colitis (IC, n=29) were divided into survival group (n=115) and death group (n=36). In comparison with the survival group, the death group had higher incidence of abdomenal effusion, portomesenteric gas, pneumatosis intestinalis and pneumoperitoneum (P
