RESUMEN

La placenta es un órgano complejo encargado de la secreción de hormonas y enzimas, realiza el transporte de nutrientes y productos metabólicos y permite el intercambio de gases. Con el aumento de la edad materna y de las cesáreas, la incidencia de placenta previa y de acretismo placentario se ha elevado, convirtiéndose ambas condiciones en problemas para la obstetricia moderna. La placenta previa se refiere a una implantación placentaria en el segmento uterino bajo, ya sea muy cerca o con algún grado de cobertura del orificio cervical interno. Suele presentarse como sangrado indoloro hacia finales del 2do trimestre. El acretismo placentario se refiere a aquella placenta que presenta un trastorno de adhesión o algún grado de invasión ya sea al útero o a estructuras adyacentes. Ambas condiciones representan un riesgo de hemorragia intraparto con alta morbilidad materna y fetal asociada. A continuación se presentan generalidades sobre estas patologías.
