What is a mesocaval shunt?

A mesocaval shunt is a surgical procedure that creates a connection between the superior mesenteric vein and the inferior vena cava. This is done in order to bypass a blockage in the portal vein, which is the main vein that carries blood from the intestines to the liver. A mesocaval shunt can be used to treat portal hypertension, which is a condition in which the pressure in the portal vein is too high. Portal hypertension can cause a number of problems, including liver damage, bleeding from the esophagus and stomach, and fluid buildup in the abdomen.

A mesocaval shunt is typically performed laparoscopically, which means that it is done through small incisions in the abdomen. The surgeon will first identify the superior mesenteric vein and the inferior vena cava. Then, they will create a connection between the two veins using a graft. The graft may be made of a piece of donor tissue or a synthetic material.

After the shunt is created, the surgeon will close the incisions. The patient will typically stay in the hospital for a few days after surgery. They may need to take medication to prevent blood clots and to reduce the risk of infection.

A mesocaval shunt is a major surgery, but it can be an effective way to treat portal hypertension. The success rate of the surgery is about 80%. The most common complication of a mesocaval shunt is bleeding from the graft. Other complications include infection, blood clots, and liver failure.
