Muestra de vellosidades coriónicas - Risks

Cuáles son los riesgos:

Los riesgos de la muestra de vellosidades coriónicas son sólo ligeramente más altos que los de la amniocentesis.

Las posibles complicaciones abarcan:

Sangrado
Infección
Aborto espontáneo
Incompatibilidad Rh en la madre
Ruptura de membranas

Los signos de complicaciones abarcan:

Sangrado excesivo
Flujo vaginal excesivo
Fiebre

Infórmele al médico sobre cualquier signo de complicaciones.

Anteriormente se creía que la muestra de vellosidades coriónicas causaba problemas de las extremidades en el feto. Cuando la muestra de vellosidades coriónicas se lleva a cabo después de las 9 semanas de edad gestacional, este riesgo parece ser muy bajo (6 por cada 10,000) y no es más frecuente que en los embarazos sin esta prueba.

Consideraciones especiales:

Si la sangre es Rh negativa, usted puede recibir RhoGAM para prevenir la incompatibilidad Rh.

Igualmente, se le hará una ecografía de control de 2 a 4 días después del procedimiento para constatar que el embarazo prosigue normalmente.
