胎盘为母儿间的重要联系器官,对胎儿的生长起决定性作用,胎盘异常或损伤均可影响胎儿的成长。文献报道畸形儿可伴有绒毛发育异常,二者可为同一致病因素所致。死产中胎儿本身的疾病较少,而胎盘(及其附属物)的情变相对较多,提示胎盘(及其附属物)异常是死产的重要原因之一,死胎的原因常不明,而胎盘的组织学检查对分析胎儿死因是有价值的。 The placenta is an important contact organ between mother and child, play a decisive role in the growth of the fetus, placental abnormalities or injuries can affect fetal growth. Reported in the literature deformity may be associated with abnormal hair growth, the two can be caused by the same risk factors. The stillbirth of the fetus itself less disease, and the placenta (and its appendages) relatively more emotional changes, suggesting that abnormal placenta (and its appendages) is one of the important causes of stillbirth, stillbirth is unknown, and the placenta Histological examination of the fetal death is valuable.
