Infarction

An infarction is a localized area of tissue death caused by a lack of blood supply to the area. This deprivation of oxygen and nutrients, known as ischemia, typically results from the blockage of a blood vessel, often by a thrombus (blood clot) or an embolus (a traveling clot or other substance). The specific clinical manifestation and severity of an infarction depend on the location, size, and duration of the ischemia. Tissue affected by an infarction undergoes necrosis, leading to the characteristic damage and potential loss of function. Prompt medical intervention is crucial to minimize tissue damage and prevent complications.

Infarction meaning with examples

• The patient experienced a myocardial infarction, commonly known as a heart attack, due to a blocked coronary artery. The lack of blood flow to the heart muscle caused significant damage. Emergency treatment was necessary to restore blood supply and prevent further damage to the heart tissues. Prompt intervention is critical for survival.
• After a stroke, the patient was diagnosed with a cerebral infarction, indicating tissue death in the brain. This resulted from a clot blocking a blood vessel in the brain. The resulting neurological deficits varied depending on the location and size of the infarct. Rehabilitation was essential for regaining lost function.
• The diagnostic imaging revealed a splenic infarction, likely caused by an embolus from another source. The spleen's tissue suffered damage because of its inability to get blood. Treatment focused on addressing the underlying cause of the embolus. The location meant that removal was not necessary.
• The renal infarction caused by a blocked kidney artery led to pain. The limited blood flow quickly destroyed tissue in the kidney. This reduced function and elevated the need for medical intervention. The patient required medications to help improve the kidney's function.
