Abstract
INTRODUCTION: Congenital lung malformations (CLMs) in pediatric patients encompass various structural abnormalities arising during fetal development, which can range from benign to life-threatening. The most common types include congenital pulmonary airway malformation (CPAM) and bronchopulmonary sequestration (BPS). AIM OF THE STUDY: This study aimed to retrospectively analyze patients treated surgically for CLMs, focusing on indications for surgery, surgical techniques, and outcomes. MATERIALS AND METHODS: Data were collected from the medical records of patients who underwent thoracoscopy (n = 140) or thoracotomy (n = 52) between 2000 and 2024. Among these, 50 patients were diagnosed with CLMs, who were taken for further analysis. Study group inclusion criteria were performing a CT/X-ray imaging examination indicating the presence of a defect, surgery, and available pathology results. Exclusion criteria were incomplete data or lack of surgical procedure. Final study group included 37 patients who met inclusion criteria for further analysis. Detailed analysis encompassed demographics, clinical presentation, diagnostic methods, treatment, and follow-up. RESULTS: The cohort included patients diagnosed with CPAM type I (n = 12), CPAM type II (n = 7), pulmonary sequestration (n = 10), and other congenital malformations such as bronchogenic cyst (n = 2), congenital cystic pulmonary disease (n = 2), CPAM type IV-pleuropulmonary blastoma type I (PPB) (n = 1), juvenile emphysema (n = 2), and mediastinal cyst (n = 1). The average age at diagnosis was 37.61 months. The cohort consisted of 17 females and 20 males. The right lung was involved in 41.18% of cases, and the left lung in 58.82%. Symptoms at presentation included pneumonia (n = 9), respiratory failure (n = 8), emphysema (n = 3), and pneumothorax (n = 2). Fifteen patients were asymptomatic, and the diagnosis was incidental. Seven patients had other congenital diseases, such as heart defects. None of the patients other than the child with PPB were offered genetic diagnostics, albeit for DICER1 or KRAS mutations. CONCLUSION: The study underscores the heterogeneity in age and clinical presentation at the time of CLM diagnosis, highlighting the importance of an individualized and tailored approach to management.
