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.
