An increased incidence of postoperative sternal infection has been rep
orted after the use of bilateral internal mammary arteries for coronar
y artery grafting. In this series, a pedicled pericardial fat pad was
mobilized to Lie in the retrosternal space before the sternum was appr
oximated. This technique was used in 101 consecutive patients who unde
rwent coronary artery grafting using bilateral internal mammary arteri
es., Twenty-four percent of the patients were diabetic, No suppurative
sternitis developed in any of these patients. (C) 1997 by The Society
