Objective: To compare the incidence of post-PDA ligation syndrome after surgical vs. percutaneous closure of PDAs in very low birth weight (VLBW) infants. Study design: Cohort study comparing 59 infants who underwent surgical ligation with 25 infants who underwent percutaneous closure. Comparisons between groups were made using two-sample t-tests and a Fisher’s exact test. Comparisons of pre vs. post variables within each group were made using paired t-tests. Results: Patients who underwent surgical ligation had a higher need for initiation of post-procedure hemodynamic support (12/59 vs. 0/24, p = 0.016), a higher post-procedure peak FiO2 (0.64 vs. 0.43, p = 0.004), and a larger absolute change in peak FiO2 (0.23 vs. 0.09, p = 0.008). Conclusion: VLBW infants who had percutaneous closure of their PDA did not experience post ligation syndrome and had less escalation of respiratory support compared with infants who underwent surgical ligation.
