Prognosis Factors for the Treatment of Pectus Carinatum With a Dynamic Compression System

Prognosis Factors for the Treatment of Pectus Carinatum With a Dynamic Compression System

Pectus carinatum is a deformation of the thoracic wall causing an aesthetic prejudice. Since 2011, our team uses a dynamic compression system to treat this deformation. It is a harness that the patient wears all day long for an average duration of 1 year, and that remodels the chest by exerting a moderate pressure on it. The local cohort is one of the largest in the world. The few previous publications have shown the validity of this method, but the prognosis factors for success of this innovative treatment are not yet identified.

The principal insvestigator hypothesizes that the success or failure of the treatment depends on several parameters assessable before treatment, such as the patient's age, gender, initial correction pressure, symmetry or not of the deformation.

Inclusion Criteria:

• Patient who received proper information about the study.
• Patient with clinically diagnosed pectus carinatum.
• Treated at Saint-Etienne University Hospital using a dynamic compression system.
• Between October 2011 and January 2020 for the retrospective part, then between January 2020 and January 2022 for the validation cohort.
• With more than 6 months of follow-up since the beginning of the treatment.
