Attempts at delayed interval deliveries in multifetal gestations have become more common. However, selection criteria are imperative to success, and placental abruption is generally considered a contraindication.
A woman with a diamniotic-dichorionic twin gestation at 23 weeks presented after a motor vehicle accident with placental abruption, hypofibrinogenemia an intrauterine fetal demise of twin A. She was expectantly managed, and the hypofibrinogenemia was nonprogressive. One week later, after delivery of twin A, a delayed interval delivery was attempted with tocolysis and antibiotics. Prolongation of the pregnancy allowed the delivery of a viable neonate.
Delayed interval delivery can be a reasonable option in the setting of placental abruption if maternal hemodynamic status is closely monitored and the patient is thoroughly counseled.
多胎妊娠时尝试延迟间隔分娩已变得更为常见。然而,选择标准对于成功至关重要,胎盘早剥通常被视为禁忌证。
一名孕23周的双羊膜囊双绒毛膜双胎妊娠女性在机动车事故后出现胎盘早剥、低纤维蛋白原血症及A胎儿宫内死亡。对她进行了期待治疗,低纤维蛋白原血症未进展。一周后,在娩出A胎儿后,尝试通过使用宫缩抑制剂和抗生素进行延迟间隔分娩。延长孕周使得一个存活新生儿得以娩出。
如果密切监测产妇血流动力学状态并对患者进行充分咨询,在胎盘早剥情况下延迟间隔分娩可以是一个合理的选择。
