Esto ocurre cuando los vasos sangu\u00edneos de la placenta compartida de los beb\u00e9s est\u00e1n conectados. Como resultado, un beb\u00e9 (este gemelo se denomina receptor) recibe m\u00e1s flujo sangu\u00edneo, mientras que el otro beb\u00e9 (este gemelo se denomina donante) recibe muy poco. El s\u00edndrome de transfusi\u00f3n feto-fetal tambi\u00e9n se conoce como s\u00edndrome de transfusi\u00f3n intergemela cr\u00f3nica. El STFF se produce aproximadamente en el <strong>15 % de los casos entre gemelos id\u00e9nticos<\/strong>. Los gemelos fraternos no corren riesgo de padecer este s\u00edndrome porque no comparten placenta.     <\/p>\n<h2>\u00bfQu\u00e9 puedo hacer para asegurarme de que mis gemelos no desarrollen el s\u00edndrome de transfusi\u00f3n feto-fetal?<\/h2>\n<p>El STFF es un evento aleatorio que no se puede prevenir haciendo o dejando de hacer algo espec\u00edfico.
