Resumen
Objetivo

Estudio detallado mediante ultrasonidos de la enfermedad asociada a una hemorragia vaginal en una amniorrexis prematura.

Sujetos y método

Se examinó ecográficamente una gestación en una diabética tipo 1 que presentó una amniorrexis prematura en la semana 31 y hemorragia vaginal.

Resultados

En la inserción placentaria del cordón se observa una brida amniótica que rodea y estrangula parcialmente la vena umbilical. Esta brida provocó un desprendimiento periférico parcial de la placenta. Mediante cesárea se confirmó el diagnóstico y se extrajo un recién nacido en buen estado.

Conclusión

En una amniorrexis, en una gestación prematura, es aconsejable una exploración ecográfica detallada antes de decidir la conducta a seguir.

Palabras clave:
Abruptio placentae

Abstract
Objective

A detailed study of way through ultrasounds on the origin of vaginal bleeding in premature rupture of the membranes.

Methods

We examined sonographically a diabetic pregnancy that showed a premature rupture of the membranes in the 31st week and vaginal bleeding.

Results

Around the placental insertion of the umbilical cord we observed an amniotic band that surrounded and strangled the umbilical vein. This band was the origin of partial abruptio placentae. Through cesarean section we confirmed the diagnosis and a normal baby was born.

Conclusion

In a premature rupture of the membranes is advisable a detailed echographic exploration before we decided the conduct to perform.
