What is Ischemia?

Ischemia is a sharp drop in the oxygen-rich blood flow in an organ tissue due to an occlusion or constriction of an artery, or one of its branches. This lack of blood supply to the tissue cells causes an area of necrosis (dead tissue) and the malfunctioning or failure of the affected organ (myocardial infarction or kedney failure). Ischemia in one limb, such as the leg, can lead to gangrene if not treated.
