OBJECTIVE To evaluate the association between in vitro fertilization (IVF) and ischemic placental disease (IPD), stratified by gestational age. DESIGN We performed a secondary analysis of a retrospective cohort study of deliveries. SETTING Deliveries were performed over 15 years at a single tertiary hospital. PATIENT(S) We included all parturients who had a live born infant or an intrauterine fetal demise (IUFD). INTERVENTION(S) We compared pregnancies resulting from IVF cycles to non-IVF pregnancies. MAIN OUTCOME MEASURE(S) The primary outcomes were preterm and term IPD (preeclampsia, placental abruption, small-for-gestational age infant [SGA], or an intrauterine fetal demise [IUFD] due to placental insufficiency). RESULT(S) Of the 69,084 deliveries during the study period, 3,763 (5.4%) were conceived with IVF. The incidence of preterm delivery was 32.6% in IVF pregnancies and 10.8% in non-IVF pregnancies. Multiple gestations were more common in IVF pregnancies. Compared to non-IVF pregnancies, IVF pregnancies were more likely to develop both preterm and term IPD, even after adjustment for maternal age and parity. The risk of preterm IPD was 4 times higher (95% confidence interval, 3.7-4.4) in patients who underwent IVF compared with those who did not undergo IVF. Among parturients who delivered at ≥37 weeks of gestation, IVF pregnancies had 1.7 times the risk of term IPD (95% confidence interval, 1.6-1.9) compared with non-IVF pregnancies. CONCLUSION(S) IVF was strongly associated with preterm IPD. We found a similar, but attenuated, association between IVF and term IPD. The stronger association with preterm IPD suggests an association between IVF and placental insufficiency.

不同胎龄体外受精与缺血性胎盘疾病的相关性

目的 评估体外受精 (IVF) 与缺血性胎盘疾病 (IPD) 之间的关联,按胎龄分层。设计 我们对分娩的回顾性队列研究进行了二次分析。地点 在一家三级医院进行了超过 15 年的分娩。患者 我们纳入了所有有活产婴儿或宫内胎儿死亡 (IUFD) 的产妇。干预措施 我们比较了 IVF 周期导致的妊娠与非 IVF 妊娠。主要结局指标 主要结局是早产和足月 IPD(先兆子痫、胎盘早剥、小于胎龄儿 [SGA] 或由于胎盘功能不全导致的宫内胎儿死亡 [IUFD])。结果 在研究期间的 69,084 次分娩中,3,763 (5.4%) 次是通过 IVF 受孕的。早产的发生率在 IVF 妊娠中为 32.6%,在非 IVF 妊娠中为 10.8%。多胎妊娠在 IVF 妊娠中更为常见。与非 IVF 妊娠相比,IVF 妊娠更可能发生早产和足月 IPD,即使在调整了母亲的年龄和产次后也是如此。与未接受 IVF 的患者相比,接受 IVF 的患者发生早产 IPD 的风险高 4 倍(95% 置信区间,3.7-4.4)。在妊娠≥ 37 周分娩的产妇中,IVF 妊娠的足月 IPD 风险是非 IVF 妊娠的 1.7 倍(95% 置信区间,1.6-1.9)。结论 (S) IVF 与早产 IPD 密切相关。我们发现 IVF 与足月 IPD 之间存在类似但减弱的关联。
