A Triplet Pregnancy With Spontaneous Delivery of a Fetus at Gestational Age of 20 Weeks and Pregnancy Continuation of Two Other Fetuses Until Week 33.

INTRODUCTION The prevalence of pregnancies with triplet or more has been increased due to using assisted reproductive treatments. Meanwhile, multiple pregnancies have higher risks and long-term maternal-fetal complications compared to twin and singleton pregnancies. Delayed interval delivery (DID) is a new approach in the management of multiple pregnancies following delivery or abortion. The purpose of this paper is to evaluate the benefits of DID and present a case that used this method. METHODS This paper covers a report on a case of triplet pregnancy resulting from assisted reproductive techniques with spontaneous delivery of a fetus at gestational age of 20 weeks and the use of conservative DID for two other fetuses until the 33rd week. RESULTS In our case, the delivery of two other fetuses occurred spontaneously at gestational age of 33 weeks after the delivery of the first fetus at week 20. CONCLUSIONS Using DID is a useful and reliable method, but requires careful monitoring, especially in patients with a history of infertility.
