Portal Hypertension Management

Causes and Classification

Portal hypertension develops from increased resistance to portal blood flow combined with increased portal venous inflow, with cirrhosis being the most common cause 1, 2, 3
The American Association for the Study of Liver Diseases recommends that cirrhosis from any chronic liver disease is the predominant cause of portal hypertension, accounting for the majority of cases 1, 2, 3
Primary biliary cirrhosis can develop portal hypertension early, even before established cirrhosis 1

The European Association for the Study of the Liver states that HVPG measurement is the gold standard for diagnosis and quantification of portal hypertension 4, 5
Normal HVPG is 1-5 mmHg, portal hypertension is >5 mmHg, clinically significant portal hypertension (CSPH) is ≥10 mmHg, and high mortality risk is ≥16 mmHg 4, 5
Non-invasive assessment alternatives include transient elastography and APRI score, with 90-96% sensitivity and 48-50% specificity at 15 kPa cutoff for transient elastography 5

The American College of Radiology recommends TIPS for refractory ascites 4
Liver transplantation should be considered for all patients with decompensated cirrhosis 4, 5
Non-selective beta-blockers (NSBBs) including carvedilol can be considered to prevent clinical decompensation in CSPH without varices 4
Combination of vasoactive agents (terlipressin, octreotide, or somatostatin) plus endoscopic therapy improves hemostasis and reduces mortality in acute variceal bleeding 4

Predictors of variceal bleeding include previous gastrointestinal bleeding, size of esophageal varices, and presence of red wale marks (longitudinal dilated venules on variceal surface) 1, 4, 7
Predictors of mortality include age, presence of ascites, extension to superior mesenteric vein, and severity of underlying liver disease (Child-Pugh score) 2, 4, 7
