coronary artery bypass的意思|示意

Coronary artery bypass surgery, or CABG, is a type of surgical procedure that helps to improve blood flow to the heart. It is usually recommended to patients who suffer from severe coronary artery disease, a condition that narrows or blocks the arteries carrying blood to the heart. CABG works by creating a bypass around the blocked artery, allowing for improved circulation of oxygen-rich blood to the heart.

During the procedure, a surgeon first identifies the blocked artery and then creates a bypass route from a healthy artery or vein, usually from the chest, leg or arm. The artery or vein is connected to the blocked or narrowed artery so that blood can flow more easily. This technique is used to improve the flow of oxygenated and nutrient-rich blood to the heart.

Following the procedure, the patient should abstain from physical activity and contact sports for at least four weeks, or as directed by their doctor, to allow the bypass grafts to heal properly. The patient may also be prescribed medications to reduce the risk of clot formation. In addition, regular follow-up visits with a doctor are required to ensure the patient is recovering well and to monitor the grafts.

Overall, coronary artery bypass surgery is an effective and proven treatment for severe coronary artery disease. While the procedure can be life-saving, it is important to recognize that it comes with risks and that close monitoring and a healthy lifestyle are essential for long-term success.
