| Unidad de Medicina Fetal Medicine fetal Unit |
Las técnicas de la reproducción humana conllevan, la estimulación ovárica, estudio y preparado del semen, cultivo y transferencia de los embriones, y todo ello con el único objetivo de conseguir una gestación. Nuestro grupo, además, realiza un seguimiento gestacional precoz: con control del crecimiento, desarrollo embrionario y fetal, para garantizar el nacimiento de un "bebé sano en casa".
Este seguimiento precoz de las primeras etapas de la gestación, es básico, antes de remitirla a su tocólogo, quien continuará con los controles necesarios. Por ello realizamos una primera ecografía para confirmar la gestación intrauterina, evaluando una correcta implantación embrionaria y observando el número de sacos gestacionales su desarrollo y viabilidad embrionaria. Con este estudio podremos emitir factores pronósticos de la evolución gestaciónal. Esta información es crucial.
Para aquellas pacientes, que requieran estudios complementarios, ponemos a su disposición diferentes técnicas de diagnóstico prenatal al disponer de personal cualificado y ecógrafos de última generación con alta resolución (Doppler color, Doppler pulsado, Eco 3/4D).
En aquellos casos que la paciente lo desee, alrededor de la semana 13 realizamos una ecografía de alta resolución haciendo especial hincapie en el estudio de los marcadores ecográficos de cromosomopatías como son la sonoluscencia ó translucencia nucal, el Doppler del ductus venoso, la presencia del hueso nasal...etc junto con un screening bioquímico para determinar que el embrión este sano. Si los resultados lo aconsejan se valorará la realización de una amniocentesis genética (extracción de líquido amniótico) para el estudio del cariotipo fetal ( estudio de los cromososmas ). En el segundo trimestre ( 20-22 semanas de la gestación ) es imprescindible practicar otra ecografía que descarte anomalías morfo-estructurales fetales. Disponemos de ecógrafo en 3/4 D ( tres dimensiones ). Durante el tercer trimestre de la gestación, la ecografia y el registro cardiotocográfico (RCTG) nos permiten confirmar el correcto desarrollo y crecimiento morfo-funcional del feto, confirmando el bienestar fetal.
The Assisted Human Reproduction ovarian stimulation is based on the study of the couple, preparation of the semen, the embryo culture and transfer, but it also includes controlling maternal and fetal well-being . That means that a healthy pregnancy as well as the intrauterine and post-natal control of the develloping baby are basic for us. We offer a close follow up during the first gestational stages, up to 13 weeks, before referring the woman to her obstetrician who will continue the appropriate controls. For those patients that, for any reason, need to undergo complementary studies, we are able to offer different techniques for pre-natal diagnosis, which will be done by qualified personal with our up- to- date equipment. A first ultrasound scan will accuratedley date the pregnancy. Fetal viability and the number and state of the vesicles are also screened, looking for an early diagnose of nonviable gestations such as deferred abortions, ectopic pregnancies, and moles. The first trimester ultrasound control, at 13 weeks of gestation,is a very reliable prenatal study, looking for echographic markers irelated to fetal chromosomopathies, such as the nuchal fold and the presence of the nasal bone, ductus venous Doppler, etc. If necessary amniocentesis (extraction of amniotic liquid to obtain an accurate diagnosis) will clarify the genetic pattern. The second trimester -aproximatedly 20 weeks- ultrasound is basic to exclude morphostructural abnormalities.
The third trimester doppler and ultrasound screen confirm the correct morpho-functional development, growth and well-being of the fetus.
