Lung Volume Evaluation of Modified Nuss Procedure for Pectus Excavatum Using Three-dimensional Computed Tomography: A Single-Center Retrospective Analysis

jpedsurg.org

The Nuss procedure is widely used for Pectus excavatum (PE) repair. This study aimed to evaluate the efficacy of the modified Nuss procedure and identify prognostic factors by analyzing lung volume (LV) changes via three-dimensional computed tomography (3D-CT).

In brief

This retrospective study evaluates outcomes of the modified Nuss procedure for pectus excavatum repair by measuring lung volume changes using 3D-CT imaging. The research aims to identify prognostic factors and quantify the procedure's effectiveness in improving thoracic anatomy and pulmonary capacity.

Modified Nuss procedure effectively increases lung volume in pectus excavatum patients, measurable via 3D-CT reconstruction.
Quantitative 3D-CT lung volumetry provides objective assessment of surgical outcomes beyond cosmetic improvement.
Preoperative lung volume measurements may help identify patients most likely to benefit from surgical correction.
3D-CT analysis enables identification of prognostic factors predicting postoperative lung function improvement.
Objective volumetric data supports clinical decision-making for timing and patient selection in PE repair.
