The restoration of blood flow to an organ or tissue that has had its blood supply cut off, as after a heart attack.
Restoration of blood supply to tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. It is primarily a procedure for treating infarction or other ischemia, by enabling viable ischemic tissue to recover, thus limiting further necrosis. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing reperfusion injury.
Restoration of blood flow to an organ or tissue.
The restoration of blood flow to an occluded (i.e., blocked) blood vessel. May be done biochemically (e.g., via tissue plasminogen activator) or via surgery.
The restoration of blood flow to a part of the body previously deprived of adequate circulation, such as the heart muscle (in myocardial infarction) or the brain (in stroke). This may be accomplished through the use of thrombolytic agents, sometimes called “clot busters” (e.g., streptokinase or tissue plasminogen activator), or mechanical interventions (e.g., balloon angioplasty). The use of these interventions has improved patient outcomes in acute coronary syndromes and patients with stroke who come to medical attention in the first few hours of their illness.
