Multiple organ dysfunction due to a rare complication of Nuss procedure for pectus excavatum: A case report.

A 19-year-old male patient who suffered from sudden and repeated multiple organ dysfunction syndrome one month after the bar removal procedure of Nuss surgery for pectus excavatum was admitted to our department. With organ function supportive treatment, the etiology was finally identified to be a bone spur located at the inner border of the left costa due to repeated friction between the implanted steel bar and the rib, which damaged the heart repeatedly and induced the consequent acute cardiac tamponade. After operation, the patient was successfully managed and discharged. Follow-ups till three years indicated a good recovery.
