Types of infarction
What is the difference between an infarct and infarction?
Infarction is tissue death (necrosis) due to inadequate blood supply to the affected area. It may be caused by artery blockages, rupture, mechanical compression, or vasoconstriction. The resulting lesion is referred to as an infarct (from the Latin infarctus, “stuffed into”).
What is an infarct and what causes it?
Infarction is tissue death or necrosis due to inadequate blood supply to the affected area. It may be caused by artery blockage, rupture, mechanical compression, or vasoconstriction. Infarction care is divided based on histopathology (white infarction and red infarction) and location (heart, brain, lung, etc.).
What is red and white infarct?
White infarctions (anemic infarcts) affect solid organs such as the heart, spleen, and kidneys. The occlusion is most often composed of platelets, and the organ becomes white, or pale. Red infarctions (hemorrhagic infarcts), generally affecting the lungs.
Does infarction mean stroke?
Infarction or Ischaemic stroke are both names for a stroke caused by a blockage in a blood vessel in the brain. This is the most common type of stroke. Blockages can be caused by a blood clot (Thrombosis) forming around fatty deposits in the blood vessels of the brain.
Is liver a red or white infarct?
The liver forms pale ischemic infarcts and red hemorrhagic infarcts of Zahn. The size of the infarct depends on the size of the occluded vessels. Pale Ischemic infarcts may result from arterial occlusion, portal vein occlusion or only from low flow, in cases of shock, without any vascular occlusion.
What is a hemorrhagic infarction?
A hemorrhagic infarct (HI) can be defined as an ischemic infarct in which an area of bleeding exists within necrosing cerebral tissue. This definition includes small hemorrhages confined to minor ischemic areas in grey matter as well as much larger lesions involving cortical and deep hemispheric regions.
What is white infarction?
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 does infarct mean in medical terms?
Medical Definition of infarct
: an area of necrosis in a tissue or organ resulting from obstruction of the local circulation by a thrombus or embolus.
What causes infarction in the lungs?
Pulmonary, or lung, infarction (PI) refers to the death of lung tissue due to a lack of blood supply. This condition is most commonly a complication of another health issue, such as pulmonary embolism (PE), sickle cell disease, amyloidosis, or vasculitis. Risk factors for PI include smoking and young age.
What are kidney infarcts?
Acute renal infarction involves occlusion of the arterial supply to the kidney and most commonly occurs as the result of thromboembolism. 1–9. Incidence in patients presenting to hospital is estimated between 0.004 and 0.007%.

Is an infarct a blood clot?
Silent cerebral infarction (SCI), or silent stroke, is a brain injury likely caused by a blood clot that interrupts blood flow in the brain. It’s a risk factor for future strokes and a sign of progressive brain damage.
How do you get an infarction?
A heart attack, also called a myocardial infarction, happens when a part of the heart muscle doesn’t get enough blood. The more time that passes without treatment to restore blood flow, the greater the damage to the heart muscle. Coronary artery disease (CAD) is the main cause of heart attack.
Is Infract a word?
infract in American English
to break, violate, or infringe (a law, commitment, etc.)
Does stress cause a stroke?
Stress can cause the heart to work harder, increase blood pressure, and increase sugar and fat levels in the blood. These things, in turn, can increase the risk of clots forming and travelling to the heart or brain, causing a heart attack or stroke.
