Successful Correction of the Recurrent Severe Pectus Excavatum with Significant Adhesions and Narrowed Intercostal Spaces in an Operated Case of Nuss Procedure: A Case Report

This case report details the management of recurrent severe PE (Pectus Excavatum) in a 14-year-old female. Despite undergoing an initial Nuss procedure with two bars in July 2023, significant chest wall depression persisted, accompanied by chest tightness and pain. Preoperative imaging confirmed recurrence and spinal scoliosis. Revision surgery on May 19, 2025, presented significant challenges due to severe adhesions and narrowed intercostal spaces. Recurrent PE necessitates the removal of the two malpositioned and transpositioned original bars. Three new imported bars were successfully implanted using the Wung and Wenlin procedures. The patient recovered well without complications and was discharged on postoperative day 7. This case highlights the technical complexities and key points of correcting recurrent severe pectus excavatum, demonstrating successful outcomes achieved through meticulous surgical planning and execution.
