La finalidad es incrementar la edad gestacional del segundo gemelo y aumentar la tasa de supervivencia.  CASO CLÍNICO:  Paciente primigesta de 39 años, con embarazo gemelar bicorial, biamniótico logrado mediante fertilización in vitro. En la semana 23 + 2 acudió a urgencias por sangrado vaginal y dolor abdominal. En la especuloscopia se observó líquido amniótico claro y dilatación cervical de 4-5 cm. El registro cardiotocográfico reportó dinámica uterina franca. En la ecografía se visualizaron dos fetos: el primero en presentación podálica sin latido cardiaco y el segundo en transversa con latido cardiaco. Después del nacimiento del primer gemelo se observó la retracción del cuello uterino y desaparición de la dinámica uterina. El estudio ecográfico mostró la bolsa amniótica íntegra, sin signos de desprendimiento placentario ni pérdida del bienestar fetal. Se propuso a la pareja la posibilidad de realizar un cerclaje cervical y diferir el parto del segundo gemelo, hecho que fue aceptado. Se consiguió prolongar la gestación del segundo gemelo 77 días, que nació mediante parto, sin morbilidad materna ni fetal.  CONCLUSIONES:  El parto diferido es una práctica adecuada para incrementar la tasa de supervivencia del feto o fetos retenidos. Los protocolos asociados con este tipo de partos son variados. Se requieren estudios adicionales para establecer los criterios de tratamiento de este tipo de partos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  BACKGROUND:  Delayed Interval delivery or asynchronous birth is when a multiple pregnancy`s fetuses are not born simultaneously, and with several day´s difference between their births. This practice´s objective is to increase the second twin´s gestational age and, as such, improve its survival rate.  CLINICAL CASE:  A 39 years-old patient with bicorial biamniotic twin pregnancy achieved by in vitro fertilization. At 23 + 2 weeks of pregnancy assisted to Emergency service for vaginal bleeding and abdominal pain. In the speculoscopy a clear amniotic fluid and cervical dilation of 4-5 cm was observed. The cardiotocographic record reported frank uterine dynamics. In the ultrasound, two files are displayed: the first in the syntax presentation in the heartbeat and the second in the transversal with heartbeat. After the birth of the first twin, retraction of the cervix and the disappearance of uterine dynamics were observed. The ecological study showed the amniotic bag intact, without signs of placental detachment or loss of fetal well-being. It was proposed to the couple the possibility of performing the cervical fence and the other part of the second day, which was accepted. It was possible to prolong the gestation of the second year to 77 days, which was born through childbirth, without registering maternal or fetal morbidity.  CONCLUSIONS:  Delayed Interval delivery is a good practice to increase the survival rate of a retained fetus or retained fetuses. The protocols associated with this type of births are varied. Additional studies are required to establish treatment criteria for this type of births.]]></p></abstract>
