The relationship between clinical diagnosis and placental findings for 561 consecutive cases of delivery at 24 to 31 weeks' gestation were analyzed, and the following results were obtained. 1) The incidence of premature rupture of the membranes (PROM), threatened premature delivery, toxemia and abruption placentae were 40.6, 36.4, 7.8 and 3.0%, respectively. 2) The incidence of chorioamnionitis, retroplacental hematoma (RPH) and placental infarction were 35.1, 18.0, and 13.0%, respectively. 3) Chorioamnionitis of the placenta was found 58.3% in PROM and 26.0% of cases of threatened premature delivery. 4) RPH was found in 70.6% of placenta of abruption and 36.4% of toxemia. 5) Placental infarction was found in 86.4% of toxemia cases and 35.3% of abruption. Each clinical diagnosis was related specifically to each placental finding in cases delivered at 24 to 31 weeks of gestation.
分析了连续561例妊娠24至31周分娩病例的临床诊断与胎盘检查结果之间的关系，得出以下结果。1）胎膜早破（PROM）、先兆早产、子痫前期和胎盘早剥的发生率分别为40.6%、36.4%、7.8%和3.0%。2）绒毛膜羊膜炎、胎盘后血肿（RPH）和胎盘梗死的发生率分别为35.1%、18.0%和13.0%。3）在胎膜早破病例中，58.3%的胎盘发现有绒毛膜羊膜炎，在先兆早产病例中，26.0%的胎盘发现有绒毛膜羊膜炎。4）在胎盘早剥病例中，70.6%的胎盘发现有胎盘后血肿，在子痫前期病例中，36.4%的胎盘发现有胎盘后血肿。5）在子痫前期病例中，86.4%的胎盘发现有胎盘梗死，在胎盘早剥病例中，35.3%的胎盘发现有胎盘梗死。在妊娠24至31周分娩的病例中，每种临床诊断都与每种胎盘检查结果有特定关联。
