目的:探讨终止异常妊娠的最佳时机。方法:根据胎头双顶径、胎盘成熟度及妊娠周数对临床病例进行对比。结果:胎儿娩出后的情况与胎盘成熟度、胎头双顶径大小不成绝对正比关系。结论:终止异常妊娠及选择妊娠的最佳时机要通过综合评估来确定。
Objective: To explore the best timing to terminate abnormal pregnancy. Methods: According to fetal head biparietal diameter, placental maturity and gestational age of clinical cases were compared.
