    Abstract:
    BACKGROUND: Video-assisted thoracoscopic surgery for patent ductus arteriosus (VATS-PDA) is an alternative surgical procedure to open chest surgery, even in premature infants. This study investigated whether the timing of VATS-PDA has a prognostic impact in premature infants whose operative indication was determined according to the symptomatic PDA and the ineffectiveness of or contraindication to indomethacine therapy. METHODS: We studied 49 infants born at or before 28 weeks of gestation who were admitted to the neonatal intensive care unit between January 2004 and June 2016, and who underwent VATS-PDA. The patients were divided into two groups according to median age at the time of surgery (early group, 24 infants who underwent surgery at ≤ 24 days of life; late group, 25 infants who underwent surgery at ≥ 25 days of life). RESULTS: No significant differences were found in bodyweight at 30 days of age and 40 weeks of corrected gestational age between the groups. The timing of surgery did not affect the operative procedure or postoperative complications. In addition, no differences were observed between the early and late groups in terms of complications associated with prematurity, including intraventricular hemorrhage, incidence and severity of bronchopulmonary dysplasia, and necrotizing enteropathy. CONCLUSION: Video-assisted thoracoscopic surgery for patent ductus arteriosus can be safely performed in premature infants without a preferential timing for the intervention, suggesting that this procedure allows for an elective basis approach after heart failure management with conservative and/or drug therapy in premature infants with PDA.
