The main<unk>  vein is formed by the union of the splenic vein and superior mesenteric vein (SMV). It is responsible for approximately three-fourths of the liver’s blood flow, transported from much of the gastrointestinal system as well as the pancreas, gallbladder, and spleen. Cirrhosis alters bleeding pathways thus patients are simultaneously at risk of uncontrolled bleeding and forming clots. A long-standing hindrance in flow as in chronic<unk> , also known as<unk>  cavernoma, can cause an increase in the hepatic venous pressure gradient<unk>  hypertension) and increased blood flow through subsidiary veins. This may lead to ascites or bleeding from varices. An infected thrombus may become septic, known as pylephlebitis; if blood cultures are positive for growth at this time, the most common organism is Bacteroides.
