Strategies to reduce sternal wound infection following coronary bypass surgery

Hyderabad: Several observational studies and meta-analysis conducted worldwide show that patients who undergo coronary bypass surgery, redo CABG (coronary artery bypass grafting) requirement at 12 years is about 40 per cent with use of single mammary artery graft and additional vein grafts and 8 per cent in patients receiving two mammary artery grafts. In the past due to apprehension of sternal wound infections after the use of two mammary artery grafts, the use of this technique was less frequent.

To alleviate the apprehension of sternal wound infections, Dr Lokeswara Rao Sajja, consultant cardiothoracic surgeon at Star Hospitals, Hyderabad and member of academic council of Indian Association of Cardiovascular and Thoracic Surgeons, reviewed the literature and experience of 340 coronary bypass surgical procedures using two mammary artery grafts and recommended several strategies to reduce sternal wound infection following coronary bypass surgery.

The study is published in the International Journal of Surgery.

According to Dr Lokeswara Rao Sajja, the review may help in promoting usage of two mammary artery grafts and thereby increasing the longevity following coronary bypass surgery. “It is more applicable to Indian populations who have coronary artery diseases at younger age and several are diabetics. People who are under 60 years and require coronary bypass surgery, it is prudent to use two mammary artery grafts during bypass surgery,” he said.
