Normal portal pressure range?

Normal: 5–10 mmHg. Portal hypertension: >10 mmHg. Clinically significant: >12 mmHg (variceal development). High: >20 mmHg (treatment failure risk, rebleeding after acute hemorrhage).

What causes elevated portal pressure?

Pre-hepatic (portal vein thrombosis), intra-hepatic (cirrhosis — most common), and post-hepatic (Budd-Chiari, cardiac cirrhosis, constrictive pericarditis) causes.

How does portal pressure monitor treatment response?

HVPG reduction >20% from baseline or to <12 mmHg with NSBBs predicts primary prophylaxis efficacy. Post-TIPS HVPG <12 mmHg predicts reduced re-bleed risk.
