What are the veins form a portacaval shunt?

Portosystemic shunts are also performed in the clinical setting to reduce the effects of portal hypertension and this can be done surgically by creating a link between the portal vein and the inferior vena cava or by creating a link between the splenic vein and left renal vein.

What is Mesocaval shunt?

Mesocaval shunts are stent grafts placed by interventional radiologists between the mesenteric system, most often the superior mesenteric vein, and the inferior vena cava. This allows flow to bypass the congested hepatic system, reducing portal pressures.

Where is the Portacaval region?

The portacaval space is a relatively narrow region between the portal vein and the inferior vena cava that is usually well seen on cross-sectional abdominal imaging studies [1].

What are vascular shunts?

By inserting a small tube (shunt) into a blood vessel, called an arterial venous shunt, they create an artificial connection between a vein and an artery. Sometimes the shunt becomes narrowed or blocked, making it difficult for blood flow.

What is Ehpvo?

Extrahepatic portal venous obstruction (EHPVO) is the commonest cause of portal hypertension and variceal bleeding in children.

What is the purpose of portacaval anastomosis?

A portocaval anastomosis or porto-systemic anastomosis is a specific type of anastomosis that occurs between the veins of the portal circulation and those of the systemic circulation. When there is a blockage of the portal system, portocaval anastomosis enables the blood to still reach the systemic venous circulation.

Where are the Paracaval lymph nodes?

The para-aortic lymph nodes (PANs) are located around the abdominal aorta and inferior vena cava and are the regional lymph nodes of the intraperitoneal organs.

What are the risks of a portacaval shunt?

Preparation To perform a portacaval shunt, a general anesthetic is required. With regard to anesthesia, major hazards include hypoxia and hypotension. In patients who have impaired liver function, there is the possible danger of using a halogenated compound, so these agents should not be employed during the surgical operation.

When are surgical shunts indicated in the treatment of variceal bleeding?

  The surgical shunts can still be an option in patients with refractory variceal bleeding with preserved liver function as well as in patients with portal hypertension. Shunts can be categorized as selective, partial, or total.
