Hepatic ischemiaIschemic hepatitis; Shock liver
Hepatic ischemia is a condition in which the liver does not get enough blood or oxygen, causing injury to liver cells.
Low blood pressure from any condition can lead to hepatic ischemia. Such conditions may include:
Low blood pressure
Low blood pressure occurs when blood pressure is much lower than normal. This means the heart, brain, and other parts of the body do not get enough ...
Other causes may include:
- Blood clots in the main artery to the liver (hepatic artery) after a liver transplant
- Swelling of blood vessels leading to reduced blood flow (vasculitis)
If 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 most often does not cause symptoms until it affects liver function.
Blood clots in the liver's main artery may cause abdominal pain.
Exams and Tests
The following tests will be done:
- Blood tests to check liver function (AST and ALT )
The aspartate aminotransferase (AST) blood test measures the level of the enzyme AST in the blood.
- Doppler ultrasound of the liver's blood vessels
Treatment depends on the cause. Low blood pressure and blood clots must be treated right away.
People generally recover if the illness causing hepatic ischemia can be treated. Death from liver failure due to hepatic ischemia is very rare.
Liver failure is a rare, but life-threatening complication.
