8.Portal hypertension leads to the formation of Portosystemic shunts, which is when blood is diverted away from the portal venous system and backs up into the systemic veins.
9.The features of portal hypertension can be remembered as ABCDE, where A stands for Ascites, B for Bleeding, C for Caput Medusae, D for Diminished liver function, and E for Enlarged spleen.
10.As the central veins and sinusoids become compressed and push on the fluid inside, their pressure starts to build up, leading to intrasinusoidal (or portal) hypertension, which is this higher pressure in the portal veins.
11.The gold standard for determining if there is portal hypertension is obtaining a hepatic venous pressure gradient measurement where a catheter is inserted inside the inferior vena cava and then inside the portal vein to measure the difference between both pressures.
