What are the few organs prone for infarction?

They occur due to arterial occlusion and are most commonly found in solid organs (spleen, kidney, heart).

Where can infarction occur?

The dead tissue is called an infarct. Myocardial infarction (heart attack)—death of a section of heart muscle—results from obstruction of a coronary artery; the condition often accompanies coronary thrombosis. Infarctions may also occur in the lungs (pulmonary infarction) and the brain (see stroke).

Which organ is prone to hemorrhagic infarction?

Red infarctions (hemorrhagic infarcts) generally affect the lungs or other loose organs (testis, ovary, small intestines). The occlusion consists more of red blood cells and fibrin strands.

In which organs does white infarct occur?

Anemic infarcts (also called white infarcts or pale infarcts) are white or pale infarcts caused by arterial occlusions, and are usually seen in the heart, kidney and spleen. These are referred to as “white” because of the lack of hemorrhaging and limited red blood cells accumulation, (compare to Hemorrhagic infarct).

What causes ischemia?

A primary cause of ischemia is atherosclerosis (hardening of the arteries). Plaque, a hard, sticky substance composed mostly of fat builds up within the arteries, causing narrowing and stiffening. This reduces blood flow.

Is liver a red or white infarct?

The acute infarct of the liver occurred because of the existing reduced blood supply from the portal vein since 4 years now complicated by the acute occlusion of the hepatic artery. The liver forms pale ischemic infarcts and red hemorrhagic infarcts of Zahn.

What causes infarction in the brain?

A cerebral infarction is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). It is caused by disrupted blood supply (ischemia) and restricted oxygen supply (hypoxia), most commonly due to thromboembolism, and manifests clinically as ischemic stroke.

What is the most common cause of hemorrhagic stroke?

Hemorrhagic stroke most often occurs when a blood vessel in the brain leaks or ruptures, which is known as a hemorrhagic conversion of an ischemic stroke or a bleeding brain tumor. Other causes include severe brain infection, head trauma, certain bleeding disorders, or an aneurysm.
