Mammary-Coronary Anastomosis: An Important Procedure in Cardiac Surgery

Introduction

Mammary-Coronary Artery Bypass (MCAB) is a surgical procedure used to restore blood supply to the heart. It is carried out by creating a connection between the mammary arteries and the coronary arteries of the heart. Mammary-coronary anastomosis is widely used in cardiac surgery as an alternative technique for myocardial revascularization in coronary disease.

Procedure

Mammary-coronary anastomosis is performed using the patient's mammary arteries. Typically, one or both internal mammary arteries (IMA) are used, which are important arteries providing blood supply to the chest. The surgeon makes a small incision in the chest wall and isolates the mammary arteries from surrounding tissue.

The surgeon then locates the coronary arteries of the heart that are suffering from ischemia or coronary disease and creates anastomoses by connecting the mammary arteries to the coronary arteries. The commonly used technique is lateral anastomosis, in which the end of the mammary artery is attached to the lateral surface of the coronary artery. This allows blood to be redirected from the mammary arteries to the coronary arteries, bypassing narrow or blocked areas of coronary blood flow.

Advantages

Mammary-coronary anastomosis has a number of advantages over other methods of myocardial revascularization. First, the use of mammary arteries allows for longer-term results because they have a higher chance of remaining open for a longer period of time compared to other arteries in the body. This is especially important for young patients who are expected to live a long time after surgery.

Second, mammary-coronary anastomosis may be more effective in bypassing blocked sections of the coronary arteries, since mammary arteries have a lower susceptibility to developing atherosclerosis.

In addition, mammary-coronary anastomosis has a low risk for patients because the body's own arteries are used, which reduces the likelihood of rejection and possible complications associated with the use of artificial prostheses.

Conclusion

Mammary-coronary anastomosis plays an important role in cardiac surgery and is an effective method for myocardial revascularization in coronary disease. The use of mammary arteries can achieve long-term results and provide more effective bypass of blocked areas of the coronary arteries. The procedure is low risk and can be done using the patient's own arteries. Mammary-coronary anastomosis continues to develop and improve, helping to improve the quality of life of patients suffering from coronary disease.
