Portal hypertension is treated by addressing its cause and preventing or managing its complications, especially variceal bleeding, ascites, spontaneous bacterial peritonitis, hepatic encephalopathy, and hepatorenal syndrome. Care should be led by a hepatologist or gastroenterologist.

1. Treat the underlying cause

  • Alcohol-associated liver disease: complete alcohol abstinence and addiction treatment.
  • Viral hepatitis: antiviral therapy when indicated.
  • Metabolic dysfunction-associated steatotic liver disease: weight, diabetes, and cardiovascular risk management.
  • Portal-vein thrombosis or other non-cirrhotic causes: cause-specific treatment, sometimes anticoagulation or vascular intervention.
  • Liver transplantation is definitive treatment for selected patients with decompensated cirrhosis or recurrent portal-hypertension complications.

2. Prevent first variceal bleed

Patients with cirrhosis and clinically significant portal hypertension need risk assessment, often including endoscopy.
  • Non-selective beta-blocker (NSBB): carvedilol, propranolol, or nadolol can lower portal pressure and reduce variceal-bleeding risk.
  • Endoscopic variceal ligation (banding): an alternative when NSBBs are contraindicated or not tolerated, and used for high-risk esophageal varices.
NSBBs need individual review, particularly with low blood pressure, acute kidney injury, severe hyponatremia, or infection. A recent review also found that response to beta-blockers is variable between patients, so monitoring matters (systematic review, PMID 38285880).

3. Acute variceal bleeding: emergency treatment

Vomiting blood, black stools, fainting, confusion, or shock in a person with liver disease is an emergency.
Hospital treatment typically includes:
  1. Airway and circulation support, with a restrictive transfusion approach in most stable patients.
  2. An IV vasoactive drug, such as octreotide, somatostatin, or terlipressin.
  3. Short-course antibiotic prophylaxis.
  4. Urgent endoscopy, generally within 12 hours, with band ligation for esophageal varices.
  5. TIPS if bleeding cannot be controlled, or early/pre-emptive TIPS for selected high-risk patients.
This AASLD summary describes vasoactive therapy, antibiotics, urgent band ligation, and rescue TIPS as the standard approach (AASLD acute-bleeding guidance). TIPS can control bleeding refractory to medicine and endoscopy in up to 90% of cases. Yamada's Textbook of Gastroenterology, p. 2559.

4. Prevent recurrent variceal bleeding

After a variceal bleed, usual secondary prevention is:
  • NSBB plus serial endoscopic band ligation
  • TIPS if bleeding recurs despite this combined treatment

5. Ascites treatment

  • Dietary sodium restriction.
  • Diuretics, commonly spironolactone with or without furosemide, with monitoring of body weight, kidney function, sodium, and potassium.
  • Large-volume paracentesis with albumin for tense or symptomatic ascites.
  • TIPS for carefully selected patients with recurrent or refractory ascites.
  • Transplant evaluation when ascites becomes refractory or recurs frequently.
TIPS controls ascites more effectively than repeated paracentesis in appropriate patients, but it can precipitate or worsen hepatic encephalopathy. Sleisenger and Fordtran's Gastrointestinal and Liver Disease, p. 1797.

6. Other complication-directed therapy

  • Spontaneous bacterial peritonitis (SBP): prompt antibiotics; certain high-risk patients need prophylactic antibiotics.
  • Hepatic encephalopathy: identify triggers, then lactulose, often with rifaximin for recurrence prevention.
  • Hepatorenal syndrome-AKI: albumin plus vasoconstrictor therapy and urgent transplant assessment.
  • Gastric varices: treatment differs from esophageal varices and may involve endoscopic tissue adhesive, TIPS, or radiologic procedures such as BRTO, depending on anatomy and local expertise.

7. Procedures

  • TIPS: a radiology-created channel between portal and hepatic veins that lowers portal pressure. It is effective for refractory bleeding and ascites but may worsen encephalopathy and is unsuitable for some people with severe liver failure, heart failure, or uncontrolled infection.
  • Surgical shunts are now less commonly used.
  • Liver transplant is the only definitive option for advanced cirrhosis with clinically significant portal hypertension.
Important: Do not start or stop beta-blockers or diuretics without clinician supervision. Sudden abdominal pain, fever, confusion, reduced urine output, vomiting blood, or black stools requires urgent medical assessment.
