Bridas amnióticas - Overview

Nombres alternativos

Pseudo-ainhum; Displasia de Streeter; Secuencia de bandas amnióticas; Síndrome de bandas amnióticas

Definición:

Son cordones de sacos llenos de líquido (saco amniótico) que rodean a un bebé en el útero y que pueden causar una deformidad congénita (presente al nacer) de la cara, los brazos, las piernas, los dedos de las manos o de los pies.

Causas, incidencia y factores de riesgo:

Las bridas amnióticas son causadas por un daño a una parte de la placenta llamada amnios. La placenta transporta la sangre hasta el bebé que aún está creciendo en el útero y el daño a la primera puede impedir su crecimiento y desarrollo normal.

El daño al amnios puede producir bandas seudofibrosas que pueden comprimir partes del feto. Estas bandas reducen el riego sanguíneo a estas áreas y hacen que se desarrollen de manera anormal.

Las bridas amnióticas son poco comunes.
