Portocaval anastomosis

A portocaval anastomosis is a specific type of anastomosis that occurs between the veins of the portal circulation and those of the systemic circulation. The inferior end of the esophagus and the superior part of the rectum are potential sites of a harmful portacaval anastomosis Porto-systemic anastomosis also known as portocaval anastomosis is the collateral communication between the portal and the systemic venous system. The portal venous system transmits deoxygenated blood from most of the gastrointestinal tract and gastrointestinal organs to the liver Portocaval Anastomosis [edit | edit source] Anastomosis is the connection between two blood vessels.

A portacaval anastomosis was not advised if there was evidence of severe liver disease, indicated by jaundice, gross ascites, or abnormal liver-function tests. Moderate ascites, however, is not a contra-indication. The liver- function test to which most weight was attached is the serum-albumin level, and no end-to-side portacaval anastomosis in this series was done on a patient whose serum-albumin level was below 3 g. per 100 ml. at the time of operation.

A pressure gradient of >50mm saline between the two vessels indicates an obstruction in the anastomosis, even when no obstruction can be palpated. In such circumstances, the anastomosis should be opened to remove any clots and, if necessary, the entire anastomosis should be taken down and redone. It is essential that there be no more than a 50mm saline gradient between the portal vein and IVC to achieve permanently adequate portal decompression and to avoid ultimate thrombosis of the shunt Prophylactic portacaval anastomoses refers to shunts constructed before the occurrence of hemorrhage from esophageal varices in the hope of preventing it.

Portacaval shunting diverts part of your blood flow from the liver. This improves blood flow in your stomach, esophagus, and intestines. Portacaval shunting is most often done when transjugular intrahepatic portosystemic shunting (TIPS) has not worked. TIPS is a much simpler and less invasive procedure. Risks. Risks for anesthesia and surgery in general are: Allergy to medicines, problems.
