过期妊娠与妊娠末期胎盘组织学的差异仅为程度不同、无明显界线,故过期妊娠胎盘的病理诊断尚无明确标准。为进一步探索过期妊娠胎盘组织学改变特点,本文研究了13例过期妊娠胎盘及9例正常对照胎盘的组织学特点,并结合临床分析讨论如下。材料与方法选择过期妊娠胎盘13例,孕期为42~(+1)～42~(+5)周。正常足月妊娠分娩胎盘9例,为对照组,孕期为38~(+1)～40~(+3)周,本组无胎儿宫内窘迫,新生儿Apgar评分均为10分。一、取材:将胎盘“米”字形切割八份,再分别
The difference between the placenta histology of late pregnancy and late pregnancy is only a different degree, there is no clear line, so there is no clear standard pathological diagnosis of placenta accreta. In order to further explore the characteristics of placental histology changes in over-pregnancy, this paper studied the histological features of 13 cases of placenta in pregnancy and 9 cases of normal control placenta, combined with clinical analysis discussed below. Materials and Methods 13 cases of placenta accretaemia were selected during pregnancy, 42 ~ (+1) ~ 42 ~ (+5) weeks during pregnancy. The normal term pregnancy delivery placenta in 9 cases, as control group, pregnancy 38 ~ (+1) ~ 40 ~ (+3) weeks, this group no fetal distress, neonatal Apgar score was 10 points. First, drawn: the placenta “m” shaped cut eight, and then respectively
