Portal vein thrombosis, incidental PM finding. 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]
Secondary Budd–Chiari syndrome, which is very rare compared to the primary variant, is due to compression of the hepatic vein by an outside structure (such as a tumor or polycystic kidney disease). [15] Budd–Chiari syndrome is also seen in tuberculosis, congenital venous webs and occasionally in inferior vena caval stenosis.
Hepatic artery thrombosis is the most common complication that occurs after liver transplantation. [2] Hepatic artery thrombosis may also occur after other surgeries. [ 2 ] Hepatic artery thrombosis and primary non-function are the two most common reason that a transplanted liver fails to work (graft failure). [ 3 ]
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 .
In one series of 33 individuals with a history of thrombosis due to congenital dysfibrinogenemia, five developed chronic pulmonary hypertension due to ongoing pulmonary embolism probably stemming form deep vein thrombosis. About 26% of individuals with the disorder suffer both bleeding and thrombosis complications. [5] [14]
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]
Typically, blood clots develop in the deep veins of the lower extremities, deep vein thrombosis (DVT) or as a blood clot in the lung, pulmonary embolism. A very small number of people who develop blood clots have a more serious and often life-threatening condition, known as thrombotic storm (TS). TS is characterized by the development of more ...
