Portal vein thrombosis (PVT) is a vascular disease of the liver that occurs when a blood clot occurs in the hepatic portal vein, which can lead to increased pressure in the portal vein system and reduced blood supply to the liver. The mortality rate is approximately 1 in 10. [1]
In medicine, hepatopulmonary syndrome is a syndrome of shortness of breath and hypoxemia (low oxygen levels in the blood of the arteries) caused by vasodilation (broadening of the blood vessels) in the lungs of patients with liver disease. Dyspnea and hypoxemia are worse in the upright position (which is called platypnea and orthodeoxia ...
In non-alcoholic fatty liver disease (NAFLD), fat builds up in the liver and eventually causes scar tissue. [52] This type of disorder can be caused by obesity, diabetes, malnutrition, coronary artery disease, and steroids. [52] [53] Though similar in signs to alcoholic liver disease, no history of notable alcohol use is found. Blood tests and ...
If acute hepatic artery thrombosis occurs after liver transplantation, then retransplantation with a new liver may be necessary. [2] However, chronic hepatic artery thrombosis may not require therapy, as the gradual development of additional blood vessels (collateral circulation) may be adequate for the metabolic needs of the liver. [2]
Portal hypertension is defined as increased portal venous pressure, with a hepatic venous pressure gradient greater than 5 mmHg. [3] [4] Normal portal pressure is 1–4 mmHg; clinically insignificant portal hypertension is present at portal pressures 5–9 mmHg; clinically significant portal hypertension is present at portal pressures greater than 10 mmHg. [5]
Blood vessels are the tubular structures of a circulatory system that ... the spleen and the liver. ... The most common disease of the blood vessels is hypertension ...
Hepatic veno-occlusive disease (VOD) or veno-occlusive disease with immunodeficiency is a potentially life-threatening condition in which some of the small veins in the liver are obstructed. It is a complication of high-dose chemotherapy given before a bone marrow transplant and/or excessive exposure to hepatotoxic pyrrolizidine alkaloids .
It is also vital in the rest of the body as the blood vessels are in charge of carrying nutrients and the discard of metabolic wastes. Therefore, blood vessel disorder can cause serious complications in the whole body. [citation needed] Coronary arteries are the blood vessels that supply to the heart for its normal function.
