Complications of the "Nuss Procedure" In Pectus Excavatum.

During the pediatric age range, one the most frequent deformities of the chest wall are Pectus Excavatum (PE). Currently the treatment of choice for PE is surgical intervention following the Nuss procedure. In this study, we present a description of the complications associated with surgical treatment of PE with the Nuss technique, in patients with symmetrical or asymmetrical deformity, in different stages of disease severity. The study was conducted in collaboration with the Pediatric Hospital "Istituto G. Gaslini" of Genoa. We analyzed a cohort of 402 patients (334 males and 68 females), who underwent corrective surgery between 2005 and 2018. Within this group of patients, we observed 82 cases with complications (20.39%), 20 of which were intraoperative (4.98%) and 62 post-operative (15.42%). For the evaluation of complications, this group was arbitrarily divided into patients with symmetric and asymmetric Pectus and in patients with mild, moderate and severe Pectus using Haller's index. Although a small group of patients presented complications, overall results from data analysis show that the Nuss technique represents the preferred surgical procedure for the treatment of PE, in agreement with literature. Furthermore, in our results show no correlation between asymmetry or severity of PE with complication related to the surgery.
