The mesocaval shunt decompresses portal hypertension with an interposition graft between the superior mesenteric vein (SMV) and the inferior vena cava (IVC). Popularized by Drapanas in the 1970s, it has had several proponents since, and most highlight that it is a shunt performed remote from the hepatic hilus. Similar in physiology to a side-to-side portacaval shunt, a mesocaval shunt diverts all portal flow if >12mm diameter, while if 8-10mm diameter some prograde portal flow is maintained.
