Sternal resection and reconstruction.

Twenty-one patients underwent sternal resection and reconstruction. Surgical indications included sternal infection in 9 patients, recurrent breast cancer in 6, metastatic carcinoma from an unknown primary in 2, pectus excavatum in 2, and osteogenic sarcoma and eosinophilic granuloma in 1 each. Management included partial sternectomy in 10 patients (group 1) and complete sternectomy in 11 (group 2). Chest wall reconstruction was by various flaps and mesh repairs. Blood transfusions averaged 2 units in group 1 versus 5.5 units in group 2 (p = 0.02). Average number of days until extubation was 2.6 in group 1 versus 7.3 in group 2 (p = 0.04). Average number of intensive care unit days was 4.4 for group 1 versus 9.4 for group 2 (p = 0.03). The number of days until discharge was 14 days for group 1 versus 20 days for group 2. Complications occurred in 40% of group 1 and 82% of group 2 patients. Overall mortality was 9.5%. Sternal resection and reconstruction, particularly complete sternal resections, are a major undertaking with substantial morbidity. Using a multidisciplinary approach (cardiothoracic, plastic and reconstructive, critical care medicine, and infectious disease) and aggressive pulmonary support, acceptable cosmetic and functional results are possible.
