9.062 deliveries took place from 1975 to 1979 at the Department of Obstetrics and Gynecology, University of Ulm. In 33 patients (0,36%) a curettage had to be performed because of late puerperal hemorrhage. Clinically mostly a placental polyp was suspected. In 10 cases (0,11%) histologic examination revealed trophoblastic tissue, in 17 cases (0,19%) decidua only and in 6 cases (0,066%) endometrium of different stages of proliferation. No correlation could be found between the mode of delivery or the placental stage and the occurrence of late puerperal hemorrhages. Also no correlation could be demonstrated between the bleedings and the number of earlier pregnancies, former curettings or uterine surgery for malformations. Comparison with earlier reports in the literature shows that the rate of late puerperal hemorrhages can be diminished by an active procedure during the placental stage. It must be pointed out that in all cases in which placental tissue can not be demonstrated histologically the term "placental polyp" should be avoided and be replaced by the term "decidual polyp".
1975年至1979年期间，乌尔姆大学妇产科共进行了9062例分娩。33例患者（0.36%）因晚期产后出血不得不进行刮宫术。临床上大多怀疑为胎盘息肉。组织学检查发现，10例（0.11%）为滋养层组织，17例（0.19%）仅为蜕膜，6例（0.066%）为不同增殖阶段的子宫内膜。分娩方式、胎盘阶段与晚期产后出血的发生之间未发现相关性。出血与既往妊娠次数、既往刮宫史或子宫畸形手术之间也未显示出相关性。与文献中早期报告的比较表明，在胎盘阶段采取积极措施可降低晚期产后出血的发生率。必须指出的是，在所有组织学检查未发现胎盘组织的病例中，应避免使用“胎盘息肉”一词，而用“蜕膜息肉”一词取而代之。
