Initial results with minimally invasive repair of pectus carinatum

Abstract

Objective: Pectus carinatum is traditionally repaired by using some modification of the open Ravitch procedure, with its possible long-term sequelae, such as poor postoperative compliance of the chest. In this study we assessed our results with a new minimally invasive repair of pectus carinatum that requires neither cartilage incision nor sternotomy. Methods: From June 2005, we have corrected pectus carinatum using a method analogous to the Nuss procedure for pectus excavatum repair. Thus far, we performed this intervention on 14 patients (mean age, 15 ± 1.5 years). A steel bar has been inserted at the level of the maximum point of the sternal protrusion through small lateral incisions. The sternum is pushed back without osteotomy or chondrotomy. The bar is removed after 2 years. Patients' characteristics, operation time, hospital stay, and complications have been recorded. Results: In 1 patient with asymmetric deformity, 2 bars were placed. Operative time was 42 ± 20 minutes (mean ± standard deviation), and hospital stay was 3 days (median quartiles, 3-4 days) postoperatively. We experienced lateral shift of the bar in 1 patient, which was treated with remodeling and repositioning of the bar. No other complication occurred during the 18-month follow-up period (mean range, 2-38 months). Thirteen of the 14 patients reported excellent or very good results. Patients returned to full activity within 2 months. Five bars have been removed. Conclusions: Minimally invasive repair of pectus carinatum leaves the integrity of the chest wall untouched. It is safe with a short operative time and hospital stay and provides good results, even in asymmetric cases. © 2009 The American Association for Thoracic Surgery.
