'

Coronary bypass surgery, also known as CABG (coronary artery bypass grafting), is a surgical procedure used to treat coronary heart disease. The procedure involves creating a bypass around a blocked section of a coronary artery, or a dead section. The bypass is created by taking a healthy artery or vein from another part of the body, such as the chest or legs, and connecting it to the damaged artery.

The procedure helps to restore normal blood flow to the heart, reducing the risk of a heart attack. It can also be used to treat certain types of heart failure.

The procedure is usually performed under general anaesthetic and takes around 3 to 6 hours to complete. Recovery times vary, but typically range from 3 to 6 weeks. During this time, the patient will have to rest and may need to take medication to reduce the risk of complications.

The success rate of coronary bypass surgery is generally very high, with the majority of patients experiencing significant improvements in their quality of life. However, there are some risks associated with the procedure, such as stroke, infection, bleeding and arrhythmias.

In summary, coronary bypass surgery is an effective way to treat certain types of heart disease. However, it is important to discuss the risks and benefits of the procedure with your doctor before deciding on whether or not to have the operation.
