Primer informe en Uruguay de la vitrificación de embriones como alternativa real a la técnica de congelación lenta
Palabras clave:
CRIOPRESERVACIÓN, VITRIFICACIÓNResumen
Introducción: la vitrificación es una técnica de criopreservación de las denominadas "rápidas". En comparación con los tradicionales procesos de congelación lenta, la estrategia de vitrificación permite la eliminación total de la formación de cristales tanto intracelular como extracelularmente. Permite poner las células directamente en el crioprotector y sumergirlas en N2 líquido. Su aplicación en el mundo ha ido creciendo exponencialmente y se puede aplicar tanto a ovocitos como a embriones en cualquier estadio.
Objetivos: revisión de la técnica de vitrificación y presentación de la experiencia de dos años en el Centro Iberoamericano de Reproducción Asistida, la primera en Uruguay.
Material y método: se incluyeron 17 pacientes de las que se han vitrificado y desvitrificado embriones. Se usó el método comercial Cryotop con las soluciones de vitrificación de Kitazato.
Resultados: con una media de embriones vitrificados de 2,71 (±0,69) por paciente, la tasa de supervivencia global de los embriones tras la desvitrificación fue de 93,4%. Con una media de embriones transferidos de 2,41 (±0,62), la tasa final de embarazo fue de 47,1%. La edad de las pacientes en las que se logra embarazo es menor (media 30,0 ±2,51) que las que no lo logran.
Conclusiones: la vitrificación como método de criopreservación se muestra prometedor y como buen sustituto de las técnicas de congelación lentas, debido a su alta tasa de éxito, su fiabilidad y la rapidez de ejecución, con resultados reproducibles.
