Abstract

Purpose: Surgical outcomes data for patent ductus arteriosus (PDA) ligation come primarily from single institution case series. The purpose of this study was to evaluate national PDA ligation trends, and to compare outcomes between pediatric general (GEN) and pediatric cardiothoracic (CT) surgeons. Methods: The Pediatric Health Information System database was queried to identify neonates who underwent PDA ligation from 2006 through 2009. Outcomes evaluated included surgical morbidity, in-hospital mortality, length of stay, and total charges. Outcomes were compared between pediatric general and pediatric cardiothoracic surgeons. Results: The records of 1,482 neonates who underwent PDA ligation were identified and analyzed. Overall mean gestational age was 26 ± 3 weeks and birth weight was 888 ± 428 g. The majority of patients among both surgeons had birth weights of B1,000 g (77.2%) and were born at B27-week gestation (81.5%). Most of the PDA ligations were performed by pediatric CT surgeons (n = 1,196, 80.7%). The mortality rate did not differ by surgeon subspecialty training (GEN = 5.2%, CT 7.9%, p = 0.16). Neonates in the cardiothoracic surgeon cohort showed lower length of stay (p < 0.001-0.05) and total hospital charges (p < 0.05) among patients with birth weight B1,200 g. Proxy measures of surgical morbidity - gastrostomy, fundoplication, and tracheostomy - showed no significant differences between the two surgical subspecialists overall or across birth weight subgroups (p > 0.05). Conclusion: These data provide a contemporary snapshot of PDA ligation outcomes at American children's hospitals. Pediatric general surgeons achieve comparable outcomes performing PDA ligation compared to pediatric cardiothoracic surgeons.
