In most previously reported cases, the pregnancy was conceived with the use of assisted reproductive technologies, and these cases were associated with complications. Case Presentation: We report a 28-year-old woman with a spontaneously conceived MCTA triplet pregnancy diagnosed at the gestational age of 26 weeks. All fetuses had normal amniotic fluid and umbilical artery Doppler findings were normal. The estimated weight of fetuses was 848 g, 891 g, and 1 kg, respectively. The patient was managed conservatively with a plan to monitor fetal growth every two weeks and a Doppler study twice weekly. On the 8<sup>th</sup> day of admission, the patient developed labor pains. Per vaginal examination revealed 1 - 2 cm cervical dilatation. Cesarean section was performed, and three girls were delivered with a single placenta (birth weight: 820, 925, and 960 g, respectively). Conclusion: Monochorionic triplet pregnancy is associated with a higher risk of fetal morbidity and mortality. Therefore, awareness of its complications can facilitate better management of such cases.展开更多

A 30-year-old woman who had undergone ICSI and the transfer of frozen-thawed embryos subsequently developed monochorionic triplet pregnancy. She did a multifetal pregnancy reduction to remove one embryo limb from the fetal sac and remained a singleton pregnancy after pregnancy reduction. At last she delivered a healthy baby girl at 40 weeks of gestation. In conclusions, an early stage fetal reduction, selection of the appropriate reduction week, and the expertise of a highly experienced doctor using ultrasound can ensure a wonderful pregnancy outcome in monozygotic multiple pregnancies.展开更多
