Letter P ( A to Z of CF 2014)
Obstruction of the portal vein – caused primarily by clots in or narrowing of the vein before it reaches the liver, cirrhosis, or high pressure in the veins that drain the liver into the heart – can cause the pressure in the vein to build up, much as blocking the end of a hose causes the pressure in the hose to climb. Increased portal vein pressure – known medically as portal hypertension – causes blood to back up in the organs that send blood to the liver. The body tries to relieve the pressure by generating new blood vessels that bypass the blockage, but such vessels are often weak and twisted, and tend to bleed easily. These vessels, called varices, may also bypass the liver itself, allowing toxins and nutrients to travel through the bloodstream unprocessed.**
