A TIPS procedure is a minimally invasive treatment that creates a new pathway for blood flow inside the liver, relieving dangerous pressure buildup in a major vein called the portal vein. The full name, transjugular intrahepatic portosystemic shunt, describes exactly what happens: a small metal tube (stent) is placed through the liver to connect two veins, rerouting blood and lowering pressure. It’s most commonly performed in people with advanced liver disease who develop complications like internal bleeding or severe fluid buildup in the abdomen.
How the Procedure Works
Your liver receives a huge volume of blood through the portal vein, which collects blood from the intestines, spleen, and stomach. When liver disease causes scarring, that blood has trouble flowing through the liver, and pressure in the portal vein rises. This condition, called portal hypertension, is the root cause of several dangerous complications.
During a TIPS procedure, an interventional radiologist threads a catheter through the jugular vein in your neck, guides it down into the liver, and creates a channel connecting the portal vein to a hepatic vein, which carries blood away from the liver. A stent is placed inside that channel to hold it open. The result is a bypass: blood that was building up behind the scarred liver tissue now has an alternate route out, and the pressure drops. The entire procedure is done through the blood vessels with no surgical incision in the abdomen.
Why It’s Performed
TIPS is reserved for complications of portal hypertension that haven’t responded well to other treatments. The most common reasons include:
- Variceal bleeding. High portal pressure forces blood into fragile, swollen veins (varices) in the esophagus or stomach. When these rupture, the bleeding can be life-threatening. TIPS reduces the pressure that causes varices to form and bleed, and it’s used both to stop active hemorrhage and to prevent rebleeding.
- Refractory ascites. Fluid accumulation in the abdomen is common in advanced liver disease. When it no longer responds to diuretics or repeated drainage procedures, TIPS can reduce the pressure driving fluid into the abdominal cavity.
- Budd-Chiari syndrome. This rare condition involves blockage of the veins that drain the liver. TIPS can restore outflow and prevent further liver damage.
Who Can and Can’t Have TIPS
Not everyone with portal hypertension is a candidate. Before the procedure, blood work is drawn to calculate a liver disease severity score called the MELD score. Patients with a MELD score above 18 or significantly elevated bilirubin levels face higher mortality risk in the three months after TIPS, so the procedure is generally only offered in those cases when no better alternatives exist.
Heart function is a critical factor. TIPS reroutes a significant volume of blood back toward the heart, which increases the workload on that side of the circulation. Congestive heart failure, severe tricuspid valve regurgitation, and severe pulmonary hypertension are all absolute contraindications because they would worsen with the extra blood flow. Patients with any history of heart problems typically undergo an echocardiogram and possibly a cardiology consultation before being cleared.
Uncontrolled infection throughout the body also rules out the procedure, since bacteria could colonize the new stent. Pre-existing hepatic encephalopathy (confusion caused by toxins the liver can’t clear) is only a contraindication when it can’t be managed with medication. If it’s well controlled, a TIPS can still be considered after a careful discussion of risks.
The Main Risk: Hepatic Encephalopathy
The most significant side effect of TIPS is new or worsened hepatic encephalopathy. This happens because the shunt diverts blood around the liver, meaning toxins that the liver would normally filter, particularly ammonia from digestion, pass directly into the general bloodstream and reach the brain. Symptoms range from mild confusion, forgetfulness, and sleep disruption to more severe disorientation.
This complication develops in roughly 30 to 50 percent of patients after TIPS placement, depending on individual risk factors and the reason for the procedure. In studies tracking outcomes, about 38 to 41 percent of patients experienced overt episodes. Most cases can be managed with medications that reduce ammonia levels in the gut, along with dietary adjustments. In rare, severe cases that don’t respond to treatment, the shunt can be narrowed or closed.
Covered Stents and Long-Term Patency
Early TIPS procedures used bare metal stents, which had a tendency to narrow over time as tissue grew through the mesh. Modern procedures almost universally use stents coated with a synthetic lining that acts as a barrier against tissue ingrowth. This advancement dramatically improved how long the shunts stay open. Covered stents maintain significantly better patency rates over the long term, and patients who receive them need fewer repeat procedures to reopen or revise the shunt.
What Follow-Up Looks Like
After a TIPS procedure, monitoring is essential to make sure the shunt stays open and functioning. The standard approach uses Doppler ultrasound, a painless imaging test that measures how fast blood moves through the stent. A typical follow-up schedule involves ultrasounds at 1, 3, 6, and 12 months after placement, then every 6 to 12 months depending on how you’re doing clinically.
During these scans, the radiologist checks several things. Blood flow speed through the stent should fall between 90 and 190 centimeters per second. Speeds outside that range may signal a narrowing. The speed of blood in the main portal vein also matters: before TIPS, it’s typically around 20 centimeters per second, and after a successful procedure it should rise above 30. If portal vein speed drops back down, that’s a sign the shunt may be developing a blockage.
The direction of blood flow in the smaller branches of the portal vein is another clue. In most patients, flow direction reverses after TIPS placement. If it flips back to the pre-procedure pattern, that often indicates a developing stenosis that may need intervention. Catching these changes early through routine ultrasound allows problems to be addressed before symptoms return.
Living After TIPS
For many patients, a successful TIPS procedure brings significant relief. Ascites that required frequent drainage may resolve or become manageable with lower doses of diuretics. The risk of another variceal bleed drops substantially. But TIPS treats the complications of liver disease, not the underlying disease itself. The liver continues to function with whatever capacity it has, and in many cases TIPS serves as a bridge, buying time while waiting for a liver transplant or stabilizing a patient enough to pursue other treatments.
Recovery from the procedure itself is relatively quick since there’s no abdominal surgery involved. Most patients spend one to two days in the hospital afterward for monitoring. The longer-term adjustment involves managing any encephalopathy symptoms, keeping up with the ultrasound schedule, and continuing treatment for the underlying liver condition.
