  2. Portal hypertension - Wikipedia

    en.wikipedia.org/wiki/Portal_hypertension

    The causes for portal hypertension are classified as originating in the portal venous system before it reaches the liver (prehepatic causes), within the liver (intrahepatic) or between the liver and the heart (post-hepatic). The most common cause is cirrhosis (chronic liver failure).

  3. Portal hypertensive gastropathy - Wikipedia

    en.wikipedia.org/wiki/Portal_hypertensive_gastro...

    Portal hypertensive gastropathy refers to changes in the mucosa of the stomach in patients with portal hypertension; by far the most common cause of this is cirrhosis of the liver. These changes in the mucosa include friability of the mucosa and the presence of ectatic blood vessels at the surface.

  4. Hepatic portal system - Wikipedia

    en.wikipedia.org/wiki/Hepatic_portal_system

    Portal hypertension is a condition in which the blood pressure of the portal venous system is too high. It is often the result of cirrhosis of the liver. Liver cirrhosis can lead to increased intrahepatic vascular resistance and vasodilation of portal system arteries, both of which increase pressure in the portal vein. [4]

  5. Portopulmonary hypertension - Wikipedia

    en.wikipedia.org/wiki/Portopulmonary_hypertension

    Portopulmonary hypertension (PPH) [1] is defined by the coexistence of portal and pulmonary hypertension. PPH is a serious complication of liver disease, present in 0.25 to 4% of all patients with cirrhosis. Once an absolute contraindication to liver transplantation, it is no longer, thanks to rapid advances in the treatment of this condition. [2]

  6. Congestive hepatopathy - Wikipedia

    en.wikipedia.org/wiki/Congestive_hepatopathy

    Macroscopically, the liver has a pale and spotty appearance in affected areas, as stasis of the blood causes pericentral hepatocytes (liver cells surrounding the central venule of the liver) to become deoxygenated compared to the relatively better-oxygenated periportal hepatocytes adjacent to the hepatic arterioles.

  7. Hepatorenal syndrome - Wikipedia

    en.wikipedia.org/wiki/Hepatorenal_syndrome

    Hepatorenal syndrome usually affects individuals with cirrhosis and elevated pressures in the portal vein system (termed portal hypertension). While HRS may develop in any type of cirrhosis , it is most common in individuals with alcoholic cirrhosis , particularly if there is concomitant alcoholic hepatitis identifiable on liver biopsies.

  8. Nodular regenerative hyperplasia - Wikipedia

    en.wikipedia.org/wiki/Nodular_regenerative...

    Nodular regenerative hyperplasia (NRH) is a rare liver disease, characterised by the growth of nodules within the liver, resulting in liver hyperplasia.While in many cases it is asymptomatic and thus goes undetected – or is only discovered incidentally while investigating some other medical condition – in some people it results in non-cirrhotic portal hypertension (NCPH).

  9. Budd–Chiari syndrome - Wikipedia

    en.wikipedia.org/wiki/Budd–Chiari_syndrome

    This leads to increased portal vein and hepatic sinusoid pressures as the blood flow stagnates. The increased portal pressure causes increased filtration of vascular fluid with the formation of ascites in the abdomen and collateral venous flow through alternative veins leading to esophageal, gastric and rectal varices.
