Abstract:Pernicious placenta previa threats maternal health and life. Although the rate of pernicious placenta previa with stillbirth or lethal fetal malformations is very low, it is a great threat to the safety of pregnant women and a great challenge to the obstetricians in clinical management. Now it is lack of clinical proven standard, so here we discuss the prenatal procedure and intrapartum treatment.

Key words: pernicious placenta previa, stillbirth, lethal fetal malformations

摘要：

凶险型前置胎盘严重威胁孕产妇生命安全。虽然凶险型前置胎盘的同时发生死胎或者致死性胎儿畸形的发生率极低，但其对孕妇生命安全有巨大威胁，给产科医生临床处置带来了极大的挑战。对于相关情况的处理，目前仍缺乏一致认可、成熟的临床处置规范。文章就此类情况产前诊断、产前准备及产时处理进行相关探讨。
