Anemic infarction of the liver resulting from hepatic and portal vein thrombosis.
True anemic infarction of the liver is a rare lesion. Most of the reported cases are due to occlusion of the hepatic artery. Whether venous occlusion can result in such anemic infarcts has been disputed although few authentic cases have been reported. A case of polycytheia vera complicated by hepatic and portal vein thrombosis with anemic infarction of a large segment of the liver is presented. The case illustrates that anemic infarcts of the liver can result from venous occlusion. The intense congestion secondary to hepatic vein occlusion may cause secondary arterial hypoperfusion unless the portal vein is available as an outflow tract.
