Ischemic hepatitis, also known as shock liver, is a condition defined as an acute liver injury caused by insufficient blood flow (and consequently insufficient oxygen delivery) to the liver. [5] The decreased blood flow ( perfusion ) to the liver is usually due to shock or low blood pressure.
The liver plays a vital role in many metabolic processes in the body including protein synthesis, detoxification, nutrient storage (such as glycogen), platelet production and clearance of bilirubin. With progressive liver damage; hepatocyte death and replacement of functional liver tissue with fibrosis in cirrhosis, these processes are disrupted.
This occurs via an increased extracellular matrix deposition around hepatocytes and sinusoidal cells which causes a peri-cellular fibrosis known as "chickenwire fibrosis". [7] This peri-cellular chickenwire fibrosis leads to portal hypertension or an elevated blood pressure in the portal veins that drain blood from the intestines to the liver. [7]
By using steroid-based drugs in autoimmune hepatitis. [57] Regularly removing a quantity of blood from a vein (venesection) in the iron overload condition, hemochromatosis. [58] Wilson's disease, a condition where copper builds up in the body, can be managed with drugs that bind copper, allowing it to be passed from the body in urine. [59]
Late complications of cirrhosis or liver failure include portal hypertension (high blood pressure in the portal vein due to the increased flow resistance through the damaged liver), coagulation disorders (due to impaired production of coagulation factors), ascites (heavy abdominal swelling due to buildup of fluids in the tissues) and other ...
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [1] [2] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [3]
The degree of rise in conjugated bilirubin is directly proportional to the degree of hepatocyte injury. Viral hepatitis can also cause the rise in conjugated bilirubin. In parenchymal liver disease and incomplete extrahepatic obstruction, the rise in conjugated bilirubin is less than the complete common bile duct obstruction due to malignant ...
The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). [2] The liver is the biggest gland of the body. It has a wide variety of functions that range from the destruction of old blood cells to the control of the whole metabolism of macromolecules. [3]
