Abstract

BACKGROUND

Surgical resection of large symptomatic congenital pulmonary airway malformation (CPAM) in newborns has high risks of mortality and postoperative morbidity. This study aimed to report the clinical outcomes of newborns who underwent percutaneous transthoracic catheter drainage (PTCD) of large symptomatic CPAM before surgical resection.

METHODS

This was a retrospective, descriptive study based on review of the medical records of newborn infants who required surgical resection of large symptomatic CPAM at a single tertiary hospital from 2001 to 2017. The clinical outcomes were compared between patients who underwent surgical resection following PTCD (PTCD group) and those who underwent surgical resection alone (non-PTCD group).

RESULTS

A total of 17 newborns were included. PTCD was performed in seven cases; the median age at the time of the initial PTCD was 4 days (range, 0-20 days). Following PTCD in all cases, chest radiograph demonstrated a dramatic reduction in the sizes of the cysts and improvement of mediastinal shift and the Alveolar-arterial oxygen difference decreased. The median duration between initial PTCD and surgery was 4 days (range, 2-33 days). PTCD-related complications included pneumothorax (n = 2), catheter displacement (n = 1), and failure to drain (n = 1). Compared with the non-PTCD group (6 of 10), the PTCD group had a tendency toward lower rates of postoperative complications (1 of 7).

CONCLUSION

PTCD can be an effective interim management for symptomatic newborn infants who require emergency surgical resection of large CPAM.
