OBJECTIVE
To examine the frequency of occurrence of chorionic villous haemorrhage in placentas with retroplacental haemorrhage, and to discuss the pathogenesis of these conditions.
DESIGN
A retrospective study using histological sections of formalin-fixed, paraffin-embedded placental tissue stained with haematoxylin and eosin.
SETTING
Department of Histopathology, Rotunda Hospital, Dublin.
SUBJECTS
Sixty cases of retroplacental haemorrhage, 34 cases of chorioamnionitis, and 24 histologically normal placentas.
MAIN OUTCOME MEASUREMENT
Presence or absence of chorionic villous haemorrhage.
RESULTS
Chorionic villous haemorrhage was present in 31 of 60 cases of retroplacental haemorrhage (51%), one of 34 cases of chorioamnionitis (2.9%) and in no normal placentas.
CONCLUSIONS
It is postulated that chorionic villous haemorrhage reflects a disturbance of fetal vascular dynamics and precedes retroplacental haemorrhage. Such a disturbance could trigger the events leading to abruption.
目的
研究胎盘后出血的胎盘中绒毛膜下出血的发生率，并探讨这些情况的发病机制。
设计
一项回顾性研究，使用苏木精和伊红染色的福尔马林固定、石蜡包埋的胎盘组织切片。
地点
都柏林罗通达医院组织病理学系。
研究对象
60例胎盘后出血病例、34例绒毛膜羊膜炎病例以及24例组织学正常的胎盘。
主要观察指标
绒毛膜下出血的有无。
结果
60例胎盘后出血病例中有31例（51%）存在绒毛膜下出血，34例绒毛膜羊膜炎病例中有1例（2.9%）存在绒毛膜下出血，正常胎盘中未发现。
结论
推测绒毛膜下出血反映了胎儿血管动力学的紊乱，且先于胎盘后出血出现。这种紊乱可能引发导致胎盘早剥的一系列事件。
