Peripancreatic vascular dissection is a procedure used in cirrhosis with portal hypertension and upper gastrointestinal hemorrhage. In cirrhosis, the portal venous return is obstructed, resulting in high pressure in the portal vein, which needs to flow back into the blood through the superior vena cava or into the inferior vena cava via collateral circulation. The most common sites of collateral circulation are at the fundus of the cardia and the vessels in the umbilicus, or at the vessels around the rectum. After the vessels around the cardia become tortuous and dilated, they may rupture spontaneously, leading to upper gastrointestinal hemorrhage, which may result in vomiting of blood and may be life-threatening in severe cases, so the vessels around the cardia need to be disconnected to reduce the incidence of upper gastrointestinal hemorrhage.
