reperfúzió

Reperfúzió refers to the restoration of blood flow to an organ or tissue that has been deprived of oxygen, typically due to a blockage. This process is crucial in treating conditions like heart attacks and strokes, where prompt restoration of blood flow can minimize damage and improve outcomes. Reperfusion can be achieved through various medical interventions, including thrombolysis, where medications are used to dissolve blood clots, and angioplasty, a procedure that uses balloons or stents to open blocked arteries. While reperfusion is vital for saving tissue, it can also paradoxically lead to further injury. This phenomenon, known as ischemia-reperfusion injury, occurs when the return of oxygenated blood to previously damaged tissue triggers inflammatory responses and the generation of reactive oxygen species, which can cause additional cellular damage. Understanding and mitigating ischemia-reperfusion injury is an active area of medical research, with ongoing efforts to develop protective strategies.
