Fig. 44-11. Portosystemic shunts. A, Portacaval shunt. The portal vein is anastomosed to the inferior vena cava,diverting blood from the portal vein to the systemic circulation. B, Distal splenorenal shunt. The splenic vein isanastomosed to the renal vein. The portal venous flow remains intact while esophageal varices are selectivelydecompressed. (The short gastric veins are decompressed.) The spleen conducts blood from the high pressureof the esophageal and gastric varices to the low-pressure renal vein.
