Persistencia del conducto arterioso en el recién nacido pretérmino: experiencia en una unidad neonatal de referencia de nivel IIIB

espanolAntecedentes y objetivos: El ductus arterioso persistente (DAP) es una patologia prevalente en el recien nacido pretermino (RNPT) que puede relacionarse con mayor morbimortalidad, siendo la tendencia actual el manejo conservador. El objetivo es describir nuestra expeciencia en una unidad neonatal de nivel IIIB, en relacion a la epidemiologia, manejo y morbi-mortalidad asociada al DAP. Material y metodos: Estudio retrospectivo observacional analitico, que incluyo RNPT menores de 32 semanas de gestacion o 1.500 g, con estudio ecocardiografico. Resultados: De 117 pacientes, 75,2% presento DAP, el 87,5% de los cuales fue hemodinamicamente significativo (DAP-HS). Todos, salvo uno, recibieron tratamiento medico. 17,2% de los DAP preciso cierre quirurgico. Los pacientes con DAP-HS presentaron mas displasia broncopulmonar (DBP) moderada-grave (p EnglishBackground and objectives: Patent ductus arteriosus (PDA) is a prevalent condition in preterm infants that may be related to increased morbidity and mortality. Current trend is a conservative management. The aim of the study was to describe our experience in a IIIB level neonatal unit in relation to the epidemiology, management and morbi-mortality associated with PDA. Patients and methods: A retrospective observational and analitical study was conducted on preterm infants less than 32 weeks of gestation or weight less than 1500 grams, in which echocardiogram was performed. Results: Of 117 patients enrolled, 75.2% had PDA, of which 87.5% were hemodynamically significant (HS-PDA). All of them, but one, received medical treatment. Surgical closure was performed in 17.2% of PDA. Patients with HS-PDA presented higher incidence of moderate-severe bronchopulmonary dysplasia (BPD) (p
