hepatic portal vein -> liver -> hepatic vein -> vena cava -> heart
The hepatic portal vein is created by the anastamoses between the superior mesenteric vein and spleinc vein. It is arguable that the inferior mesenteric vein joins at this sam…e anastomoses but generally it actually joins the splenic vein which then meats the sup. mesenteric vein as stated above. The veins that drain into the portal vein (ie above the ansastmoses between the splenic and sup. mesenteric) are the cystic vein, the right gastric vein and the posterior-superior part of the pancreaticoduodenal vein.

Carries blood from the stomach and abdominal organs to the liver. High pressure (usually caused by cirrhosis of the liver due to alcoholism) causes bleeding in the esophagus.
Massive internal bleeding caused by high pressure in the portal vein occurs in about 40% of patients with cirrhosis. Patients who survive are likely to need a portal vein bypa…ss to control bleeding.
There are 2 portal vein bypasses available, portacaval shunting and splenorenal shunting.
