凝固性坏死:小肠出血性梗死

小肠出血性梗死
图示:小肠出血性梗死(又称红色梗死)。暗红甚至是灰色的梗死肠段与下部的粉红色正常肠段有着明显的区别。一些器官如肠侧支循环较多,或者如肝有双重血液供应,很难发生梗死。但这段肠发生了肠疝,由于疝环很小,因此肠系膜动脉供血明显减少。

The small intestine is infarcted. The dark red to grey infarcted bowel contrasts with the pale pink normal bowel at the bottom. Some organs such as bowel with anastomosing blood supplies, or liver with a dual blood suppy, are hard to infarct. This bowel was caught in a hernia and the mesenteric blood supply was constricted by the small opening to the hernia sac.
