A serious and potentially life-threatening condition that arises when a considerable mass of body tissue dies (necrosis).

Death and decay of body tissue, often occurring in a limb, caused by insufficient blood supply and usually following injury or disease.

Death and putrefaction of tissue usually due to a loss of blood supply.

Death of tissue in part of the body because blood has stopped flowing there.

Death of tissue, usually in considerable mass and generally associated with loss of vascular (nutritive) supply and followed by bacterial invasion and putrefaction.

Gangrene is a complication of necrosis characterized by the decay of body tissues. There are two major categories: infectious gangrene (wet gangrene) and ischemic gangrene (dry gangrene). The condition may result from ischemia, infection, or trauma (or a combination of these processes). Ischemia may result from either arterial or venous...

Gangrene, localized death of animal soft tissue, caused by prolonged interruption of the blood supply that may result from injury or infection. Diseases in which gangrene is prone to occur include arteriosclerosis, diabetes, Raynaud's disease, thromboangiitis obliterans (Buerger's disease), and...
