It is often defined as a portal pressure gradient (the difference in pressure between the portal vein and the hepatic veins) of 10 mmHg or greater.

Famous quotes containing the word portal:
“Some sepulcher, remote, alone,
Against whose portal she hath thrown,
In childhood, many an idle stone—
Some tomb from out whose sounding door
She ne’er shall force an echo more,
Thrilling to think, poor child of sin!
It was the dead who groaned within.”
—Edgar Allan Poe (1809–1849)
