BACKGROUND: Although complete video-assisted thoracic surgery (C-VATS) has been demonstrated to have several advantages compared with conventional thoracotomy, there are few reports on the clinical feasibility of C-VATS for CPAM in infants. METHODS: We retrospectively evaluated 13 consecutive patients (neonates 4; infants 9) surgically treated for congenital pulmonary airway malformation (CPAM) from 1 January 2008 to 31 March 2017. RESULTS: In the group of neonates, all 4 cases were prenatally diagnosed and they underwent semi-emergent surgery after birth due to respiratory failure. In the group of 9 infants, 5 cases were prenatally diagnosed and 4 cases were diagnosed at age >2.5 years due to symptoms associated with pulmonary cystic infection. Pulmonary resection consisted of the following: 8 lobectomies, 1 segmentectomy, 2 wedge resection, 1 fractionated lung resection and 1 lobectomy with segmentectomy. Overall, there were 9 thoracotomy and 4 thoracoscopic surgeries. Mean operation time was 162 min (range, 67-290 min) and blood loss was 21 mL (range, 0-74 mL) on average. There were no complications such as thoracic deformity or respiratory failure, however in 2 of those who underwent segmentectomy the cystic remnant remained. No statistically significant differences were observed between the thoracotomy Group and C-VATS group in terms of age and height at intervention, operation time, blood loss, postoperative day of drain removal, and length of hospital stay after surgery. However, only the average body weight was heavier in C-VATS group (P=0.03). CONCLUSIONS: Since early surgical resection of asymptomatic CPAM is often recommended for the prevention of infections and the development of lung malignancy, we recommend performing surgery after the age of 1 year if the patient's condition is stable. Furthermore, C-VATS lobectomy may be feasible if they are older than 18 months or weigh more than 10 kg. 2019 Journal of Thoracic Disease. All rights reserved.
