Treatment for Portal Hypertension in Cirrhosis
The treatment of portal hypertension must be stratified by disease stage, with etiological therapy as the foundation for all patients, non-selective beta-blockers (NSBBs) for those with clinically significant portal hypertension and varices, and transjugular intrahepatic portosystemic shunt (TIPS) reserved for refractory complications. 1, 2
Stage-Based Treatment Algorithm
Stage 1: Mild Portal Hypertension (HVPG 5-10 mmHg)
Focus exclusively on treating the underlying liver disease—NSBBs are ineffective and should not be initiated at this stage. 1, 3
- Eliminate etiological factors: alcohol cessation, antiviral therapy for hepatitis B/C, weight loss for NAFLD, immunosuppression for autoimmune hepatitis 1, 3
- Do NOT start NSBBs: The hyperdynamic circulatory state is not fully developed, making NSBBs mostly ineffective and potentially harmful with increased adverse events 1
- Surveillance: Repeat endoscopy every 2-3 years if compensated, or when decompensation occurs 1
Stage 2: Clinically Significant Portal Hypertension Without Varices (HVPG ≥10 mmHg)
Continue aggressive etiological treatment but do NOT initiate NSBBs for "preprimary prophylaxis" of varix formation. 1
- A large multicenter trial showed timolol provided no benefit over placebo in preventing varices (39% vs 40%, P=0.89) but caused significantly more serious adverse events (18% vs 6%, P=0.006) 1
- Surveillance: Endoscopy every 2 years with ongoing liver injury, or every 3 years if liver injury is quiescent 1
Stage 3: Small Varices (F1)
NSBBs or carvedilol may be considered only in high-risk patients with small varices. 1, 2
- High-risk criteria: Child-Pugh B/C cirrhosis OR red color signs on varices 1, 2
- Low-risk patients: Surveillance endoscopy every 1-2 years; NSBBs optional but not mandatory 1
- Carvedilol option: May delay progression to large varices (20.6% vs 38.6% with placebo at 24 months, P=0.04) due to additional alpha-1 blockade reducing intrahepatic resistance 1
Stage 4: Large Varices (F2/F3) or High-Risk Small Varices
Initiate NSBBs immediately—this is the cornerstone of primary prophylaxis. 1, 2, 4
First-Line NSBB Therapy:
- Carvedilol 12.5 mg/day: Superior to traditional NSBBs, achieving hemodynamic response in 50-75% of patients versus 46% with propranolol/nadolol 2, 3
- Alternative traditional NSBBs: Propranolol 40 mg twice daily (titrate to 80 mg twice daily) or nadolol, targeting 25% heart rate reduction or resting HR of 55 bpm 2, 4
- Target hemodynamic response: HVPG reduction to <12 mmHg or >10-20% decrease from baseline protects against acute variceal bleeding 2, 5
Alternative: Endoscopic Variceal Ligation (EVL)
- EVL is equivalent to NSBBs for primary prophylaxis (RR 0.86,95% CI 0.55-1.35) 1
- NSBBs are preferred as they reduce portal pressure globally and prevent other complications beyond bleeding 4
Management of Specific Complications
Ascites
Sodium restriction (2000 mg/day) plus oral diuretics are the mainstays of treatment. 1
- Initial diuretic regimen: Spironolactone 100 mg + furosemide 40 mg once daily in the morning 1, 6
- Fluid restriction is NOT necessary unless severe hyponatremia (<120-125 mmol/L) develops 1
- Monitor 24-hour urinary sodium: Goal >78 mmol/day (88 mmol intake - 10 mmol nonurinary losses) 1
- Albumin therapy: In selected patients, long-term albumin use reduces further decompensation and improves survival 7
Critical safety warning: In patients with refractory ascites and hypotension (systolic BP <90 mmHg or MAP <65 mmHg), NSBBs should be temporarily suspended or used with extreme caution 2, 3
Portal Hypertensive Gastropathy (Chronic Bleeding)
Manage with portal pressure-lowering strategies, not blood products. 1, 4
- Chronic setting: NSBBs (propranolol or nadolol) are recommended to reduce bleeding severity and mortality 1, 4
- Propranolol dosing: Start 40 mg twice daily, titrate to 80 mg twice daily or maximal tolerated dose 4
- Adjunctive therapy: Iron supplementation for iron-deficiency anemia; oral iron is usually sufficient 2, 4
- Refractory cases: Consider endoscopic argon plasma coagulation or TIPS 4
Acute Variceal Bleeding
Initiate vasoactive drugs immediately when variceal hemorrhage is suspected, before endoscopy. 2, 4, 3
Immediate Management Protocol:
- Vasoactive drugs: Octreotide, somatostatin, or terlipressin—start immediately 2, 4, 3
- Prophylactic antibiotics: Ceftriaxone 1 g IV daily (maximum 7 days) reduces mortality, infections, and rebleeding 2, 3
- Restrictive transfusion strategy: Start transfusion at hemoglobin 7 g/dL with goal 7-9 g/dL—excessive transfusion paradoxically increases portal pressure 1, 2, 3
- Endoscopy within 12 hours: Perform EVL once hemodynamically stable 2, 3
- Continue vasoactive drugs 2-5 days post-endoscopy, then transition to oral NSBBs 2
Do NOT use tranexamic acid in active variceal bleeding—this is contraindicated. 2, 3
Do NOT routinely correct coagulation abnormalities before prophylactic band ligation in stable patients—this provides no benefit and is not recommended 2, 3
Refractory Complications
TIPS is strongly recommended for variceal bleeding refractory to endoscopic and medical therapy. 4, 3
TIPS Indications:
- Refractory variceal bleeding: Failure of endoscopic and pharmacological therapy 4, 3
- Early/preemptive TIPS: Consider within 72 hours in high-risk patients (Child-Pugh C or MELD ≥19) 2, 4, 3
- Refractory or recurrent ascites: Selected patients who fail medical management 4, 3
TIPS Contraindications:
- Bilirubin >50 μmol/L, platelets <75×10⁹, pre-existing encephalopathy, active infection, severe cardiac failure, severe pulmonary hypertension 4
- Hepatic encephalopathy affects approximately one-third of patients after TIPS and usually responds to medical therapy 4
Critical Safety Considerations
When to Suspend NSBBs:
- Acute bleeding with hypotension: Systolic BP <90 mmHg or MAP <65 mmHg 2, 3
- Refractory ascites with hypotension: Use extreme caution or suspend temporarily 2, 3
Absolute Contraindications to NSBBs:
- Severe bradycardia, heart block, severe asthma, decompensated heart failure 3
Blood Product Administration:
Administering large volumes of blood products paradoxically increases portal pressure and may worsen bleeding—use restrictive transfusion strategies 1, 2
Monitoring and Long-Term Management
- Hemodynamic response is usually sustained long-term (maintained in 81% of cases), primarily influenced by medication compliance and alcohol intake 5
- Responders have significantly better outcomes: Lower probability of developing ascites (P<0.001), encephalopathy (P=0.001), need for transplantation (P=0.002), and improved survival (P=0.029) 5
- HVPG monitoring can guide therapy when available, though not recommended routinely outside clinical trials 1
Definitive Treatment
Liver transplantation should be considered in all patients with decompensated cirrhosis—it is the most effective approach to reduce portal pressure and improve survival. 2, 3
