+If the portal vein is occluded for any reason, there can theoretically be infarct from the stomach (rare) to and including the superior third of the rectum. The infarct is haemorrhagic because of the rich blood supply of the <abbr>GI</abbr> tract due to its many anastomoses between the two mesenteric arteries. Another contributing cause to who it is haemorrhagic is because there is almost always venous backflow from the portal vein. This backflow can be caused by cardiac failure and any kind of liver disease.
