## Direct answer

Transjugular intrahepatic portosystemic shunt, or TIPS, is an image-guided stent placed between a hepatic vein and a portal vein branch to lower portal pressure without open surgery. It is used for refractory ascites, variceal rebleeding despite beta-blockers and band ligation, and Budd-Chiari syndrome as a bridge to definitive treatment. Hepatic encephalopathy is its main drawback, because the stent diverts portal blood past the liver.

## What you must remember

- **Physiology:** a covered stent creates a low-resistance channel from a hepatic vein to an intrahepatic portal branch, lowering the portal pressure gradient.
- **Significant portal hypertension:** a hepatic venous pressure gradient of 10 mmHg or more defines clinically significant portal hypertension, and 12 mmHg or more marks high risk of variceal bleeding.
- **Post-TIPS target:** a gradient below 12 mmHg is the usual aim, since persistently higher values predict rebleeding and ascites.
- **Main indications:** refractory ascites, recurrent variceal bleeding despite standard therapy, and Budd-Chiari syndrome.
- **Key contraindications:** right heart failure, pulmonary hypertension and severe tricuspid regurgitation, because the shunt raises venous return to the right heart.
- **Relative risks:** severe liver failure and polycystic liver disease raise the risk of a poor outcome after the procedure.
- **Encephalopathy:** the commonest complication, managed with lactulose and rifaximin, with stent narrowing reserved for persistent cases.
- **Stent type:** covered stents resist restenosis better than bare metal stents, which is why covered stents are the usual choice.

## A bleeding cirrhotic with tense ascites

A 54-year-old man with alcohol-related cirrhosis has had two variceal bleeds despite propranolol and band ligation. His ascites needs repeated large-volume paracentesis, and the question is whether TIPS is the right next step.

1. **Measure the gradient:** The hepatic venous pressure gradient is measured during the same procedure, and a value of 10 mmHg or more confirms clinically significant portal hypertension.
2. **Screen the heart:** Echocardiography looks for right heart failure, pulmonary hypertension and tricuspid regurgitation, since the shunt raises right atrial pressure and can precipitate cardiac failure.
3. **Grade liver reserve:** Child-Pugh class and bilirubin are reviewed, because advanced liver failure carries higher post-TIPS mortality and encephalopathy risk.
4. **Place the stent:** Under fluoroscopy, a needle passes from a hepatic vein into a portal vein branch, the tract is dilated and a covered stent is deployed.
5. **Re-measure the pressure:** The gradient is recorded again, with the aim of bringing it below 12 mmHg.
6. **Treat encephalopathy early:** Lactulose and rifaximin are started, and persistent symptoms may need the stent narrowed.
7. **Follow up with Doppler:** Ultrasound checks stent patency, and recurrent ascites or bleeding suggests stent dysfunction.

## Where the examiner tests the wrong choice

Questions on TIPS usually test who should be excluded and what the shunt does to the brain and the heart.

- **Trap:** choosing TIPS for a patient with heart failure because it is less invasive — **Correct:** right heart failure and pulmonary hypertension are contraindications, since the shunt increases venous return to the right heart.
- **Trap:** assuming encephalopathy is rare after a percutaneous procedure — **Correct:** it is the commonest complication, managed with lactulose and, when needed, stent narrowing.
- **Trap:** using TIPS as first-line therapy for every variceal bleed — **Correct:** beta-blockers and band ligation come first, and TIPS is reserved for rebleeding or high-risk early bleeders.

## Frequently asked questions

### Which portal pressure gradient is targeted after TIPS?

After TIPS, the usual aim is to bring the hepatic venous pressure gradient below 12 mmHg, which lowers the risk of variceal rebleeding. A gradient of 10 mmHg or more before the procedure marks clinically significant portal hypertension and helps identify patients who may benefit from TIPS.

### What is the commonest complication of TIPS?

Hepatic encephalopathy is the commonest complication of TIPS, because the stent lets ammonia-rich portal blood bypass the liver. It is treated with lactulose and rifaximin, and persistent cases may need the stent narrowed to reduce the shunt.

### Which conditions contraindicate TIPS?

Right heart failure, pulmonary hypertension and severe tricuspid regurgitation are the key contraindications to TIPS, because the shunt increases venous return to the right heart. Severe liver failure and polycystic liver disease are treated as relative contraindications that raise the risk of a poor outcome.

### How does TIPS compare with surgical portosystemic shunts?

TIPS is a percutaneous procedure that avoids laparotomy, whereas surgical portosystemic shunts need major abdominal surgery and are now uncommon. Both lower portal pressure, and TIPS is usually the first choice in most centres for suitable patients.

### Why are covered stents preferred in TIPS?

Covered stents, usually made of polytetrafluoroethylene, resist restenosis better than bare metal stents, so the shunt stays open for longer. Better patency reduces the chance of recurrent ascites or bleeding after TIPS.
