Hepatic encephalopathy (HE) is an altered level of consciousness as a result of liver failure. [2] Its onset may be gradual or sudden. [ 2 ] Other symptoms may include movement problems, changes in mood , or changes in personality . [ 2 ]
One scheme defines "acute hepatic failure" as the development of encephalopathy within 26 weeks of the onset of any hepatic symptoms. This is sub-divided into "fulminant hepatic failure", which requires onset of encephalopathy within 8 weeks, and "subfulminant", which describes onset of encephalopathy after 8 weeks but before 26 weeks. [ 6 ]
The exact definition of "rapid" is somewhat questionable, and different sub-divisions exist which are based on the time from onset of first hepatic symptoms to onset of encephalopathy. One scheme defines "acute hepatic failure" as the development of encephalopathy within 26 weeks of the onset of any hepatic symptoms.
Increased pressure in the sublobular branches of the hepatic veins causes an engorgement of venous blood, and is most frequently due to chronic cardiac lesions, especially those affecting the right heart (e.g., right-sided heart failure), the blood being dammed back in the inferior vena cava and hepatic veins.
The physiological findings that correlate with worsening portal hypertensive gastropathy include an increased portal venous pressure gradient and decreased hepatic blood flow. [4] Biopsies of the stomach in patients with portal hypertensive gastropathy show ectatic (or dilated) blood vessels, evidence of bleeding by means of red blood cells in ...
Liver disease, or hepatic disease, is any of many diseases of the liver. [1] If long-lasting it is termed chronic liver disease . [ 3 ] Although the diseases differ in detail, liver diseases often have features in common.
The list of conditions associated with chronic liver disease is extensive and can be categorised in the following way: [3]. Viral causes. Hepatitis B; Hepatitis C; Cytomegalovirus (CMV), Epstein Barr virus (EBV), and yellow fever viruses cause acute hepatitis.
Autoimmune hepatitis, formerly known as lupoid hepatitis, plasma cell hepatitis, or autoimmune chronic active hepatitis, is a chronic, autoimmune disease of the liver that occurs when the body's immune system attacks liver cells, causing the liver to be inflamed.
