Hepatic ischemia?
by

1 Answer

Answer :

DefinitionHepatic ischemia is a condition in which the liver does not get enough blood or oxygen, causing injury to liver cells.Alternative NamesIschemic hepatitis; Shock liverCauses, incidence, and risk factorsLow blood pressure from any condition can lead to hepatic ischemia. Such conditions may include:Abnormal heart rhythmsDehydrationHeart failureInfectionSevere bleedingOther causes may include:Large blood clots in the main artery to the liver (hepatic artery) after a transplantSwelling of blood vessels (vasculitis)SymptomsIf low blood pressure continues for a long time, you may feel weak and lightheaded. However, the period of low blood pressure may be brief and produce no symptoms. Damage to the liver cells usually does not cause symptoms.Signs and testsBlood levels of liver enzymes,
