A case of an adolescent boy with persistent thoracic symptoms and recurrence of pectus excavatum (after previous treatment with the Nuss procedure) is presented. During thoracoscopic revision, subdiaphragmatic migration of the implant was noted. The bar was removed without damage to the intra-abdominal organs or other complications, and a new bar was placed and stabilised. Revision showed successful correction of the thorax, and the boy had no thoracic symptoms.
