Bypass Surgery

Bypass surgery (pronunciation: /ˈbʌɪpɑːs ˈsɜːrdʒəri/) is a type of surgery that involves redirecting blood flow around a blocked or partially blocked artery in the heart.

Etymology

The term "bypass" originates from the English language, meaning to avoid something by going around it. In the context of surgery, it refers to the process of creating a new pathway for blood flow to "bypass" a blocked artery. The term "surgery" comes from the Greek "cheirourgia", meaning "hand work".

Procedure

Bypass surgery, also known as Coronary Artery Bypass Grafting (CABG), involves taking a blood vessel from another part of the body (usually the chest, leg, or arm) and attaching it above and below the blocked area of the heart. This allows blood to bypass the blocked area, hence the name of the procedure.

Related Terms

  • Coronary artery disease: This is the most common reason for bypass surgery. It occurs when the arteries that supply blood to the heart muscle become hardened and narrowed due to the build-up of cholesterol and other material, called plaque, on their inner walls.
  • Angina: This is chest pain or discomfort caused by coronary heart disease. It occurs when the heart muscle doesn't get as much blood as it needs.
  • Myocardial infarction: Also known as a heart attack, this occurs when a part of the heart muscle doesn't receive enough blood flow.

Risks and Complications

Like all surgeries, bypass surgery carries risks. These can include Infection, Bleeding, Arrhythmia, Stroke, or even death. It's important to discuss these risks with your doctor before the procedure.
