Budd-Chiari Syndrome

Budd-Chiari syndrome is a condition resulting from the interruption of the normal outflow of blood from the liver Liver The liver is the largest gland in the human body. The liver is found in the superior right quadrant of the abdomen and weighs approximately 1.5 kilograms. Its main functions are detoxification, metabolism, nutrient storage (e.g., iron and vitamins), synthesis of coagulation factors, formation of bile, filtration, and storage of blood. Liver. The primary type arises from a venous process (affecting the hepatic veins Veins Veins are tubular collections of cells, which transport deoxygenated blood and waste from the capillary beds back to the heart. Veins are classified into 3 types: small veins/venules, medium veins, and large veins. Each type contains 3 primary layers: tunica intima, tunica media, and tunica adventitia. Veins or inferior vena cava) such as thrombosis, but can also be from a lesion compressing or invading the veins Veins Veins are tubular collections of cells, which transport deoxygenated blood and waste from the capillary beds back to the heart.

Ascites, and abdominal discomfort. Onset is often subacute or chronic. Diagnosis is confirmed by Doppler ultrasound. Treatment involves addressing the underlying condition that caused the venous occlusion. Further management involves prevention of further clotting (anticoagulation), restoration of blood flow, and decompressing the liver Liver The liver is the largest gland in the human body.

Liver cirrhosis Cirrhosis Cirrhosis is a late stage of hepatic parenchymal necrosis and scarring (fibrosis) most commonly due to hepatitis C infection and alcoholic liver disease. Patients may present with jaundice, ascites, and hepatosplenomegaly. Cirrhosis can also cause complications such as hepatic encephalopathy, portal hypertension, portal vein thrombosis, and hepatorenal syndrome. Cirrhosis.

Epidemiology

  • In non-Asian countries:

    • Affects men predominantly
    • Pure IVC or combined IVC and hepatic vein blockage more common

Etiology

  • Hypercoagulable Hypercoagulable Hypercoagulable states (also referred to as thrombophilias) are a group of hematologic diseases defined by an increased risk of clot formation (i.e., thrombosis) due to either an increase in procoagulants, a decrease in anticoagulants, or a decrease in fibrinolysis. Hypercoagulable States disorders (80%):
    • Polycythemia vera Polycythemia vera Polycythemia vera (PV) is a chronic myeloproliferative neoplasm characterized by the overproduction of RBCs. In addition, the WBC and platelet counts are also increased, which differentiate PV from erythrocytosis seen with chronic hypoxia and other chronic conditions.

    • Paroxysmal nocturnal hemoglobinuria Paroxysmal Nocturnal Hemoglobinuria Paroxysmal nocturnal hemoglobinuria (PNH) is a rare but serious acquired hemolytic anemia with periodic exacerbations. This anemia is caused by nonmalignant clonal expansion of ≥ 1 hematopoietic stem cells that have acquired a somatic mutation of the phosphatidylinositol N-acetylglucosaminyltransferase subunit A (PIG-A) gene. Paroxysmal Nocturnal Hemoglobinuria (PNH)
    • Antiphospholipid syndrome Antiphospholipid syndrome Antiphospholipid syndrome (APLS) is an acquired autoimmune disorder characterized by the persistent presence of antiphospholipid antibodies, which create a hypercoagulable state. These antibodies are most commonly discovered during a workup for a thrombotic event or recurrent pregnancy loss, which are the 2 most common clinical manifestations. Antiphospholipid Syndrome

Liver disease (viral hepatitis, alcoholic liver disease Alcoholic Liver Disease Alcoholic liver disease is a spectrum of disorders ranging from fatty liver to cirrhosis secondary to chronic alcohol abuse. Excessive and prolonged consumption of alcohol results in impairment of the lipolysis pathway, causing inflammatory changes within the hepatocytes. Patients typically present during the hepatitis stage with jaundice, fever, and abdominal pain. Alcoholic Liver Disease, drug-induced hepatitis): Different types of liver Liver The liver is the largest gland in the human body. The liver is found in the superior right quadrant of the abdomen and weighs approximately 1.5 kilograms. Its main functions are detoxification, metabolism, nutrient storage (e.g., iron and vitamins), synthesis of coagulation factors, formation of bile, filtration, and storage of blood. Liver disease also present with a similar presentation ( jaundice Jaundice Jaundice is the abnormal yellowing of the skin and/or sclera caused by the accumulation of bilirubin. Hyperbilirubinemia is caused by either an increase in bilirubin production or a decrease in the hepatic uptake, conjugation, or excretion of bilirubin. Jaundice, ascites Ascites Ascites is the pathologic accumulation of fluid within the peritoneal cavity that occurs due to an osmotic and/or hydrostatic pressure imbalance secondary to portal hypertension (cirrhosis, heart failure) or non-portal hypertension (hypoalbuminemia, malignancy, infection). Ascites, hepatomegaly). These conditions can have acute and chronic onset. Progression of liver Liver The liver is the largest gland in the human body. The liver is found in the superior right quadrant of the abdomen and weighs approximately 1.5 kilograms. Its main functions are detoxification, metabolism, nutrient storage (e.g., iron and vitamins), synthesis of coagulation factors, formation of bile, filtration, and storage of blood. Liver injury, regardless of cause, can lead to cirrhosis Cirrhosis Cirrhosis is a late stage of hepatic parenchymal necrosis and scarring (fibrosis) most commonly due to hepatitis C infection and alcoholic liver disease. Patients may present with jaundice, ascites, and hepatosplenomegaly. Cirrhosis can also cause complications such as hepatic encephalopathy, portal hypertension, portal vein thrombosis, and hepatorenal syndrome. Cirrhosis and portal hypertension Hypertension Hypertension, or high blood pressure, is a common disease that manifests as elevated systemic arterial pressures. Hypertension is most often asymptomatic and is found incidentally as part of a routine physical examination or during triage for an unrelated medical encounter. Hypertension. History (medication, alcohol, exposure), laboratory tests, and imaging studies aid in determining the etiology of liver Liver The liver is the largest gland in the human body.
