Reperfusion
Reperfusion
Reperfusion (pronounced: ree-per-FYOO-zhun) is a medical term referring to the restoration of blood flow to an organ or tissue that was previously ischemic, meaning it had a reduced blood supply.
Etymology
The term "reperfusion" is derived from the Latin re- meaning "again" and perfusio meaning "a pouring over".
Definition
Reperfusion is the process of restoring blood flow to an area of the body after it has been blocked. This can occur naturally when a clot or other obstruction in the blood vessels is removed or dissolved. It can also be induced medically, such as in the treatment of stroke or myocardial infarction (heart attack), where it is crucial to restore blood flow as quickly as possible to minimize damage to the affected tissue.
Related Terms
- Ischemia: A condition in which blood flow (and thus oxygen) is restricted or reduced in a part of the body.
- Reperfusion injury: Damage to tissues caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen.
- Thrombolysis: The breakdown (lysis) of blood clots by pharmacological means, and commonly called clot busting.
- Angioplasty: A minimally invasive, endovascular procedure to widen narrowed or obstructed arteries or veins, often used to treat conditions that cause reduced blood flow.
