 The aim of this study was to clarify the pathological features of small intestinal ischemic lesions. We examined 132 lesions from 132 cases with ischemia(strangulation, mesenteric arterial thrombosis, mesenteric venous thrombosis, others, and ischemic enteritis : 101, 12, 3, 6, and 10 lesions, respectivity)between January, 2003 and March 2013 at our laboratory.

 The following results were obtained. The macroscopic and microscopic findings indicating that the ischemic lesion had been caused by mesenteric venous thrombosis were extensive hemorrhage, edema and congestion. The chronic phase(stricture form)of ischemic enteritis was macroscopically characterized by marked tubular stenosis and circular girdle ulcer with rough-surfaced texture. Microscopically, ulcers(UL-IIs or IIIs)with vascular-rich granulation tissue and prominent fibromusculosis of the submucosal tissue were also found at the lesions.
