OBJECTIVE: To determine the main congenital lung malformations treated and the principal diagnostic methods employed, as well as the indications for surgical treatment and the results obtained, at a referral facility for pediatric thoracic surgery. METHODS: We reviewed the medical charts of 52 patients anatomopathologically diagnosed with congenital lung malformations and who had been submitted to pulmonary resection between January of 1997 and December of 2006. Exclusion criteria were age > 12 years and incomplete clinical data. The final sample comprised 35 patients. RESULTS: In this sample, the mean age was 31 months, and there was a predominance of males (n = 21). The anatomopathological findings were cystic adenomatoid malformation (n = 14), congenital lobar emphysema (n = 13), pulmonary sequestration (n = 8) and arteriovenous malformation (n = 1). The most common type of lung resection was left lower lobectomy (in 25.71%) followed by different types of segmentectomy (in 22.85%), left upper lobectomy (in 22.85%), right upper lobectomy (in 14.28%), right lower lobectomy (in 8.57%) and middle lobectomy (in 5.71%). Of the 35 patients, 34 (97.14%) were submitted to closed pleural drainage, with a mean duration of thoracic drainage of 3.9 days. Ten patients (28.5%) presented with postoperative complications. There were no deaths in our sample. CONCLUSIONS: Pulmonary resection for the treatment of congenital lung malformations is a safe procedure, presenting low morbidity and no mortality at a referral facility for pediatric thoracic surgery.
