During a CABG procedure, a surgeon takes a healthy blood vessel from another part of the body, such as the chest or leg, and uses it to create a new path for blood to flow around the blocked or narrowed coronary artery. The new blood vessel, called a graft, is attached to the coronary artery above and below the blockage, allowing blood to bypass the blocked area and reach the heart muscle.
CABG is typically recommended for patients with severe coronary artery disease who have not responded to other treatments such as medication or lifestyle changes. The procedure is usually performed under general anesthesia and typically requires a hospital stay of several days.
CABG is a major surgical procedure and carries some risks, such as bleeding, infection, stroke, or heart attack. However, it can be very effective in improving blood flow to the heart and reducing symptoms such as chest pain or shortness of breath. Patients should discuss the risks and benefits of CABG with their healthcare provider to determine if it is the right course of action for their individual needs.
