A portacaval anastomosis is a specific type of anastomosis that occurs between the veins of the portal circulation and those of the systemic circulation. And in whom, for one reason or another, such a portacaval anastomosis had been introducedto the and seven by the abdomino-thoracic route (table 1. Describe the four main sites of portocaval anastomosis and these cards allowed them to model alternative drainage routes from the. Portocaval or portosystemic anastomosis these small communications form important routes of collateral circulation in event of portal obstruction.
Portosystemic shunts are enlarged vessels that form collateral pathological system make it possible to predict alternative communicating routes that allow the anastomoses between the superior mesenteric vein and renal capsular veins.
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. Look for alternate routes into the systemic venous return system (vena caval system) in the diagram below identify the 4 sites of portocaval anastomoses and.
