摘要
目的比较不同类型前置胎盘对妊娠结局的影响。方法回顾分析2003年1月至2012年12月10年间北京大学第一医院住院分娩的343例前置胎盘患者的临床资料，比较其中325例不同类型单胎前置胎盘患者的一般情况和妊娠结局。结果325例中完全性前置胎盘组221例，部分性前置胎盘组22例，边缘性前置胎盘组82例。完全性和部分性前置胎盘患者产次及剖宫产次数、胎盘附着于子宫后壁概率、产前出血量、输血机会及新生儿窒息率高于边缘性前置胎盘患者（P〈0．05）；这两组的分娩孕周和新生儿体重低于边缘性前置胎盘组（P〈0．05）。3组胎盘粘连、胎盘植入及产妇产后24h出血量差异无统计学意义（P〉0．05）。结论前置胎盘患者的分娩孕周、产前出血量、是否输血、胎盘位置、新生儿结局与前置胎盘的类型有关：完全性前置胎盘组和部分性前置胎盘组比边缘性前置胎盘组差；而胎盘粘连、胎盘植入及产妇产后出血量与前置胎盘类型无关。
Objective To explore the maternal and perinatal outcomes for different types of placenta previa （PP）. Methods A total of 343 pregnancies with PP from January 2003 to December 2012 at our hospital were retrospectively reviewed. The general profiles, maternal and perinatal outcomes of different types of 325 singleton PP were evaluated. Results Among them, 221 pregnancies were of complete PP. There were partial （ n = 22） and marginal （ n = 82） PP. Proportions of previous vaginal and cesarean deliveries in women with complete and partial PP were higher than those with marginal PP （P 〈 0. 05）. Compared with marginal PP group, ratio of placenta in the uterus posterior wall prepartum hemorrhage and probability of blood transfusion and neonatal asphyxia were much higher in complete and partial PP. The gestational age at delivery and neonatal body weight with complete PP and partial PP marginal PP were higher than those of the other two groups （P 〈 0.05 ）. As for the placenta adhesion, placenta accrete or postpartum hemorrhage, no difference existed among three groups placenta location. Conclusion The gestational age at delivery, prepartum hemorrhage, probability of blood transfusion and perinatal outcome in women with PP are related with the type of PP. Both complete and partial PP have relatively worse outcomes. The type of PP has no effect on placenta adhesion, placenta accrete or postpartum hemorrhage.
