A treatment of intractable sternal osteomyelitis--significant use of pedicle muscular flaps

In recent years, the greater omentum of pedicle muscular flap has been used to treat chest wall infection and Sternal Osteomyelitis following cardiac or respiratory surgery. In Japan, however, there has been an increasing number of cases in which neither the greater omentum Nor the rectus muscle can be used due to the comparatively young age of the patient. There are also many cases undergoing abdominal surgery for malignant tumor and bypass surgery of the coronary artery in which the internal thoracic artery (ITA) and gastroepiploic artery (GEA) are used. We studied three such cases; a case of coronary aortic bypass graft (CABG) where ITA from both the right and left sides were used following stomach resection; a case in which CABG and gallbladder resection were carried out simultaneously; and a case of sternal osteomyelitis is years following surgery for ventricular septal defect. All three cases had undergone reconstructive surgery using the pectoralis major muscle or a pedicle muscular flap from the latissimus dorsi muscle. It is estimated that cases of CABG using both the right and left sides of ITA and GEA, cases of the elderly as well as cases of children will continue to increase. Consequently, cases of sternal osteomyelitis in which neither the omentum nor rectus muscle can be used will also increase. Therefore, it is considered that treatment using pedicle muscular flaps from the breast or dorsal area may be very effective. Herein, we report on the choice of treatment and its results.
