What term describes necrotic tissue that results from a loss of blood supply?

The term that accurately describes necrotic tissue resulting from a loss of blood supply is gangrene. Gangrene specifically refers to the death of body tissue due to a lack of blood flow, often accompanied by infection, which can lead to tissue decay. This is particularly important in the context of understanding conditions that compromise blood circulation, such as peripheral artery disease or serious injuries, which can lead to gangrenous changes in tissues.

While ischemia refers to a reduced blood supply to tissues, it does not inherently mean that the tissue is necrotic; ischemia can exist without resulting in tissue death if blood supply is restored in time. Necrosis, on the other hand, is a general term for tissue death but does not specify the cause, whereas gangrene explicitly involves a combination of necrosis alongside the complicating factors of infection and a significant lack of blood flow. Fibrillation pertains to a type of serious heart arrhythmia and is not relevant to the context of tissue death due to loss of blood supply. Understanding these distinctions is crucial for accurate diagnosis and treatment in medical practice.
