What is TIPS?
Transjugular Intrahepatic Porto-Systemic Shunt (abbreviated as TIPSS or TIPS) is a procedure used to reduce portal hypertension, a condition that often affects patients with severe liver disease. Normally, blood flows through the liver from the esophagus, stomach, and intestines. When the disease has damaged portions of the liver, blood flow is often blocked, which increases pressure on the blood vessels feeding the liver, often to the point of causing them to rupture. This can cause intestinal bleeding, life-threatening esophageal bleeding, and a buildup of fluids in the abdomen.
The TIPS procedure is performed to re-establish blood flow by creating a tunnel between two veins.
Our interventional radiologist create a shunt by first gaining access to the liver through the internal jugular vein in the neck, using fluoroscopic guidance to insert a thin needle and sheath into one of the patient’s hepatic veins, and then inflating a tiny angioplasty balloon to create a tunnel between it and the portal vein.
A stent or thin wire frame is then guided into place along this tunnel to maintain the tract between the higher-pressure portal vein and the lower-pressure hepatic vein.
Fluoroscopy or ultrasound imaging are used to ensure proper placement of the shunt, and afterwards measurements are taken in the portal vein and right atrium to ensure that pressure has been relieved. Your interventional radiologist can in most cases tell you immediately how well the procedure worked. The procedure is considered much safer than surgery because no large incisions need to be made, and has become widely accepted as the preferred method of treating portal hypertension.
