| Sumario: | Management of patent ductus arteriosus is still controversial. This study aimed to describe the impact of a more conservative approach on treatment rates and on main outcomes of prematurity, especially in preterm infants with <26 weeks of gestation. Clinical charts review of infants ≤30 weeks with patent ductus arteriosus between 2009 and 2016 at two centers. In 2011, the authors changed patent ductus arteriosus management: in first period (2009-2011), patients who failed medical treatment underwent surgical closure; in second period (2012-2016), only those with cardiopulmonary compromise underwent surgical ligation. Medical treatment, surgical closure, mortality, and survival-without-morbidity were compared. This study included 188 patients (27 ± 2 weeks, 973 ± 272 grams); 63 in P1 and 125 in P2. In P2, significantly lower rates of medical treatment (85.7% P1 versus 56% P2, p < 0.001) and surgical closure (34.5% P1 versus 16.1% P2, p < 0.001) were observed. No differences were found in chronic lung disease (28.8% versus 13.9%, p = 0.056), severe retinopathy of prematurity (7.5% versus 11.8%, p = 0.403), necrotizing enterocolitis (15.5% versus 6.9%, p = 0.071), severe intraventricular hemorrhage (25.4% versus 18.4%, p = 0.264), mortality (17.5% versus 15.2%, p = 0.690) or survival-without-morbidity adjusted OR = 1.10 (95% CI: 0.55-2.22); p = 0.783. In P2, 24.5% patients were discharged with patent ductus arteriosus. The subgroup born between 23 and 26 weeks (n = 82) showed significant differences: lower incidence of chronic lung disease (50% versus 19.6%, p = 0.019) and more survival-without-morbidity (20% versus 45.6%, p = 0.028) were found. A conservative approach in preterm infants with patent ductus arteriosus can avoid medical and surgical treatments, without a significant impact in survival-without-morbidity. However, two-thirds of preterm infants under 26 weeks are still treated. |
