HVPG: What It Is, Why It Matters, and How It Guides Liver Disease Treatment
When your liver is damaged — from alcohol, hepatitis, or fatty disease — blood struggles to flow through it. That’s where HVPG, hepatic venous pressure gradient, a direct measurement of pressure inside the liver’s blood vessels. Also known as hepatic venous pressure gradient, it’s the gold standard for spotting portal hypertension before serious problems like bleeding or fluid buildup happen. Unlike scans or blood tests, HVPG gives doctors a real number — not a guess — about how hard the heart has to work to push blood through a stiff, scarred liver.
HVPG doesn’t just diagnose. It tells you what to do next. If the reading is above 12 mmHg, you’re at risk for varices — swollen veins in the esophagus that can burst and cause life-threatening bleeding. Above 16 mmHg? Your body’s starting to hold onto fluid, leading to ascites. And if HVPG drops by 20% or more after treatment, your chances of surviving improve dramatically. That’s why doctors use it to track how well meds like beta-blockers are working, or whether a procedure like TIPS (a shunt placed in the liver) actually helped. It’s not just a test — it’s a treatment roadmap.
HVPG is tied to other key players in liver health. Liver cirrhosis, the scarring that turns healthy tissue into stiff, nonfunctional scar tissue is the main reason HVPG rises. And portal hypertension, the high pressure in the vein that carries blood from the gut to the liver is the direct result. You can’t fix one without understanding the other. That’s why every article in this collection — whether it’s about managing ascites, preventing variceal bleeding, or choosing the right meds — ties back to HVPG. These aren’t random posts. They’re all connected by one simple truth: if you’re treating liver disease without checking HVPG, you’re flying blind.
What you’ll find below are real, practical guides on how HVPG shapes decisions — from which drugs to prescribe, when to refer for a shunt, and how to monitor progress over time. No theory. No fluff. Just what matters when your liver is under pressure.
