What is a Peritoneovenous shunt used for?

Peritoneovenous shunt is a device that relieves ascites by transferring fluid through a one-way valve from the peritoneal cavity into the superior vena cava.

What is a percutaneous shunt?

The shunt catheter venous limb is cut to the proper length, inserted through a peel-away sheath, and placed into the superior vena cava via the percutaneous internal jugular vein venotomy. The pump is “re-primed” by compressing the pump at least 25 times.

Where is a Denver shunt placed?

A Denver shunt, or peritoneovenous shunt, is a device used to shunt ascites to the superior vena cava in patients with refractory ascites. The proximal end is located in the peritoneal cavity and the distal end in the superior vena cava, with a subcutaneous course in the anterior chest wall.

How does Denver shunt work?

Placement of Denver pleurovenous shunt with a pump chamber allows unidirectional flow of fluid from the pleural cavity to the central venous system. It helps replace the lost plasma volume in the central venous system by shunting the pleural fluid to the superior vena cava.

What is a LeVeen?

Medical Definition of LeVeen shunt : a plastic tube that passes from the jugular vein to the peritoneal cavity where a valve permits absorption of ascitic fluid which is carried back to venous circulation by way of the superior vena cava.

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.

What is a VP shunt for hydrocephalus?

VP shunts are placed to treat hydrocephalus. Hydrocephalus (hi-droh-SEF-eh-less) happens when CSF does not drain out of the hollow spaces inside the brain (called ventricles) as it should. VP shunts drain the extra fluid and help prevent pressure from getting too high in the brain.

How does a shunt work for ascites?

They put in a tube that has one end in the abdominal fluid and one end in the vein in the neck. A valve in the tube allows fluid to flow from the tummy into the vein in the neck. The fluid then returns back into the bloodstream.

What is intractable ascites?

Definition: intractable ascites. intractable ascites. A condition in which excess fluid continually builds up in the abdominal or peritoneal cavity despite appropriate medical therapy.
