تعریف و معنای "bypass"

What is a "bypass"?

A bypass refers to a surgical procedure used to create a new path for blood flow when arteries, which are the blood vessels that carry oxygen-filled blood from the heart throughout the body, become blocked or narrowed because of conditions like coronary artery disease. During this procedure, a healthy blood vessel is typically taken from another part of the body, such as the leg, and attached to redirect blood around the blocked artery, restoring enough blood supply to the heart muscle. Bypass surgery is often performed to relieve chest pain or to reduce the risk of heart attack in individuals with serious coronary artery disease. It can improve blood flow and overall heart function, helping patients manage heart-related symptoms and improve their quality of life.
