Minimally invasive repair of pectus carinatum using the Abramson technique.

In the past, the treatment of pectus carinatum has been managed by open, invasive surgical procedures, which involved the resection of cartilage growth plates (Ravitch procedure). By preventing normal bony growth and maturity, this technique often led to postoperative complications, such as acquired thoracic dystrophy, chronic pain and scarring, and stiffness of the whole anterior chest. Dyspnea and exercise intolerance due to restricted thoracic space and cardiac compression were not uncommon as well. Over the last 2 decades, nonsurgical and minimally invasive approaches have gained ground because it was recognized that simple sternal compression was able to remodel the elastic anterior chest wall and therefore correct pectus carinatum adequately/efficiently, at least in children. However, failure of this compressive brace treatment is not uncommon in adolescents and older patients. Abramson therefore developed a minimally invasive technique for the correction of pectus carinatum using a pectus bar that is placed anteriorly to the sternum. The procedure is less invasive and less risky than a pectus bar inserted for pectus excavatum, but the lateral fixation of the pectus bar in the Abramson procedure remains a challenge. We demonstrate the technical aspects of the procedure step by step including our solution for fixation of the stabilizers.
