Abstract

Objective: To describe morphological characteristics and severity of congenital pectus excavatum in patients treated at Cho Ray Hospital. Methods: A cross-sectional study was conducted on 200 patients with pectus excavatum at Cho Ray Hospital. Evaluated parameters included Park H.J. classification, Haller index (HI), chest wall asymmetry index (CWAI), vertebral index (VI), sternal rotation angle, and their relationship with scoliosis. Results: Male patients predominated (82%), with a male-to-female ratio of 4.5:1. The mean age was 15.56 ± 5.75 years. Symmetric type accounted for 55.5%, and asymmetric type 44.5%. The mean HI was 3.6 ± 0.7, with the severe group accounting for the highest proportion (44.5%). Scoliosis was present in 10% of patients, mostly right-sided. Significant associations were found between Park H.J. classification and CWAI (p < 0.001), as well as between Park H.J. classification and VI (p = 0.011). Conclusion: Congenital pectus excavatum is more common in males, typically presenting during adolescence. CT-based morphological indices, particularly HI and CWAI, are valuable in assessing severity and guiding surgical management.
