Abstract:
Pectus excavatum is the most common congenital abnormality of the chest wall. It may lead to adverse psychosocial development and preoccupation with a negative body image. The Nuss procedure is a minimally invasive approach for improving these patients' body image. The most dangerous complication is cardiac perforation from the insertion of the introducer. Our technique modifies this procedure to include a small subxiphoid incision and a novel sternal lift system that elevates the sternum. This facilitates the insertion of the introducer and placement of the pectus bar(s), and it reduces the risk of intraoperative cardiac perforation.
