Abstract: Stillbirth is the final outcome of maternal，fetal and placental diseases under various risk factors. The predictive value of stillbirths due to impaired placentation using a combination of maternal factors，fetal biometry，uterine artery Doppler and maternal serum placenta growth factor during the first and  second trimester was high，but it is limited  for term stillbirths.Correct identification of high-risk factors of stillbirth，strengthening the management of preconception and pregnancy in high-risk groups，using various prenatal monitoring methods effectively and timely delivery can  reduce the occurrence of stillbirth.

Key words: stillbirth, prediction, risk factors, prevention

摘要： 死胎是各种高危因素下母体、胎儿、胎盘疾病的终末期结局。早中孕期联合母体病史、超声胎儿生长及子宫动脉多普勒血流评估、母体血清胎盘生长因子，对胎盘受损所致死胎的预测价值较高，但对足月死胎的预测价值有限。正确识别死胎的高危因素，加强高危人群的孕前及孕期管理，有效利用各种产前监护手段以及适时分娩，可降低死胎的发生率。
