TIPS complications: encephalopathy, shunt stenosis, bleeding and heart failure

How the shunt works and why it changes the risks

A radiologist reaches the liver through the jugular vein and places a stent connecting the portal circulation to a hepatic vein. Portal blood now has a low-resistance path back to the heart, which reduces pressure in varices and helps control refractory ascites. It is commonly considered when variceal bleeding or fluid buildup does not respond to endoscopic or medicine-based treatment. The patient often stays in hospital at least overnight, with the head of the bed raised for several hours after the procedure.

The same rerouting explains the main complications. Blood that bypasses the liver carries toxins the liver would normally clear, which can cause encephalopathy. A sudden extra volume returning to the right heart can unmask heart failure. And because the stent can narrow over time, symptoms of portal hypertension may come back weeks or months later.

Watch for new or worsening hepatic encephalopathy

Encephalopathy may follow any portosystemic shunt, including TIPS. Early signs are easy to miss: reversed sleep pattern, poor concentration, slowed responses, changed handwriting and the flapping tremor of asterixis. Compare mental status against the pre-procedure baseline at each assessment, and ask family members whether behaviour seems different.

Look for precipitants the team can address, such as infection, dehydration, low potassium, gastrointestinal bleeding, constipation, and sedatives or opioids. Report deterioration and anticipate prescribed bowel-cleansing therapy such as lactulose and sometimes rifaximin. Teach the patient and family to recognise confusion at home, because encephalopathy after TIPS can appear after discharge. Avoid giving sedating medicines to a newly confused patient without first discussing the change with the prescriber, because sedatives can deepen encephalopathy and mask a decline.

Bleeding, cardiac strain and infection after the procedure

Monitor the neck puncture site for bleeding or haematoma, and watch for abdominal bleeding shown by falling blood pressure, rising heart rate, abdominal pain or a dropping haemoglobin. Injury to the hepatic artery or liver capsule is uncommon but serious, so instability after TIPS is escalated urgently rather than assumed to be sedation effect.

Assess for heart failure and rhythm problems: new breathlessness, crackles, raised jugular venous pressure, oedema or palpitations. Contrast can affect kidney function, so track urine output and kidney tests. Fever may follow the procedure, but persistent fever raises concern about stent or bloodstream infection and should be reported. Patients with pre-existing kidney impairment are at higher risk, so a falling urine output after contrast should be reported early rather than at the end of the shift.

Shunt stenosis and a hypothetical follow-up question

Stenosis or occlusion of the stent allows portal pressure to rise again. The clinical clue is recurrence of the original problem: returning ascites, new variceal bleeding or rising weight from fluid. Follow-up ultrasound is used to confirm the shunt remains open, and a narrowed shunt may need revision. Ultrasound is usually done soon after the procedure and repeated during follow-up, so missed appointments are a genuine safety issue.

Consider a hypothetical patient seen several weeks after TIPS whose abdominal girth and weight are rising again. Options include increasing dietary protein, reassuring that fluid is expected after TIPS, restricting all fluids, or reporting for shunt assessment. Reporting is best because returning ascites suggests shunt dysfunction. The other options either ignore the warning sign or apply an intervention without assessment.

Teaching and documentation after TIPS

Teach the patient to keep follow-up imaging appointments, avoid alcohol and sedating medicines unless prescribed, and report confusion, black stools, vomiting blood, increasing abdominal swelling, breathlessness or fever. Family members are often the first to notice subtle mental changes, so include them in teaching when the patient agrees.

Document baseline and serial neurological assessment in the same terms each time, the puncture site, vital sign trends, weight and girth, and bowel pattern. Consistent descriptions let the next nurse spot a gradual decline in mental status or a slow return of ascites that a single snapshot would miss.
