ABSTRACT

La vasa previa es una patología poco frecuente en la que los vasos umbilicales se encuentran transcurriendo en las cercanías del orificio cervical interno. Habitualmente está asociada a inserción velamentosa del cordón, placenta succenturiata, inserción baja placentaria y fertilización in vitro. Tiene importantes implicancias perinatales el lograr un diagnóstico precoz en el segundo trimestre, porque se logra disminuir la mortalidad neonatal. Presentamos el primer caso de diagnóstico prenatal de vasa previa tipo 3 (una variante poco conocida) comunicado en el Perú en una gestante con placenta previa y sin diagnóstico hasta el tercer trimestre.


Vasa previa is a rare condition in which the umbilical vessels are found to run in the vicinity of the internal cervical os. It is usually associated with velamentous insertion of the umbilical cord, placenta succenturiata, low placenta insertion and in vitro fertilization. Early diagnosis in the second trimester has important perinatal implications because it reduces neonatal mortality. We present the first case of prenatal diagnosis of vasa previa type 3 (a little known variant) reported in Peru in a pregnant woman with placenta previa and undiagnosed until the third trimester.
