If a venous hum is present over the xiphoid region or umbilicus and is heard over the chest, suspect hepatic cirrhosis with portal systemic anastomoses (Cruveilhier-Baumgarten syndrome).

Anastomoses. The importance of portosystemic anastomoses is to provide alternative routes of circulation when there is a blockage in the liver or portal vein.

These routes ensure that venous blood from the gastrointestinal tract still reaches the heart through the inferior vena cava without going through the liver. Portosystemic Anastomosis. A portosystemic shunt is the diversion of portal blood into a systemic vein without the blood passing through the liver and may be extrahepatic (e.g.

congenital atresia of the portal vein) or intrahepatic, resulting from a connection between the portal venous system within the liver and either the hepatic veins or inferior vena cava. portal-systemic anastomosis: Any of the venous connections between the portal circulation and the main systemic circulation.

These veins provide alternative routes by which venous blood normally shunted through the liver can reach the inferior vena cave and then the heart. Veins in the portal circulation have no valves; thus blood can travel.

Porto-systemic anastomosis Portal caval system A portacaval 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 names: Porto-systemic anastomosis Portal caval system. Anastomosis is the connection between two blood vessels. Portocaval anastomosis includes all the connections made between veins of the portal circulation and the systemic circulation.

The major areas where the two systems anastomose are the following. Portacaval Anastomosis 1. General Plan of Blood Circulation PORTAL CIRCULATION Blood is collected from one set of capillaries and is passed to a larger vessel which then again divides into capillaries before the blood is returned to systemic circulation.

Portal-systemic Anastomoses When the liver is damaged however, for example in cirrhosis from chronic alcohol abuse, the vascular bed in the hepatic parenchyma is reduced.

Therefore at a constant flow rate the same volume of blood must be pushed out of the portal vein via fewer vessels. Watch the video lecture "Portal-systemic Anastomoses – Portal System" & boost your knowledge.

4. Portosystemic shunts, also known as portosystemic collaterals, are abnormal communications between the portal system and the systemic circulation, and such shunts can be congenital or acquired (7,8). Congenital shunts can be intrahepatic or extrahepatic, and their classification is complex.

The study of such shunts is beyond the scope of this.
