BACKGROUND/PURPOSE: The Ravitch repair of pectus excavatum removes segments of abnormal costal cartilages after which the sternum is elevated and stabilized. Some investigators have found a worsening in total lung capacity postoperatively. Recently, a technique has been used in which the costal cartilages are preserved, and the sternum is elevated with an internal steel bar (Nuss repair). The authors hypothesized that placement of a substernal bar in the first stage of the Nuss repair will not adversely affect pulmonary and exercise function. METHODS: Patients who presented to the Children's Hospital of Buffalo for surgical repair of pectus excavatum from June 1997 through June 2000 underwent pulmonary function and exercise testing before and 6 to 12 months after the first stage of a Nuss repair. RESULTS: Ten patients were studied (all boys; mean age at operative repair, 13.4 +/- 3 years). Mean baseline pulmonary function was normal, and no significant differences were seen before and after placement of the intrathoracic bar. Peak oxygen consumption was near normal, although work at VO2max was less than predicted (mean, 68.2% before v. 71.8% after surgery). V(E) was below normal and Vt/FVC was below the expected 50% to 60% level both before and after surgery (41.3% +/- 3 SE and 41.6% +/- 3 SE pre- and postoperatively, respectively). CONCLUSIONS: Placement of a substernal steel bar in the first stage of the Nuss procedure for repair of pectus excavatum does not cause adverse effects on either static pulmonary function or on the ventilatory response to exercise.
