The placentary conditions (weight of placenta, placenta/infant weight index, kind of attachment of the umbilical cord and allantochorial vasculature) of underweight neonates (eutrophic premature infants and hypotrophic babies born at term), which were macroscopically determined under routine clinical conditions, are compared with those of eutrophic babies born at term after clinically and anamnestically normal pregnancies. Significantly lower weights of placenta and significantly higher placenta/infant weight indices of underweight neonates must be differently assessed for prematurely born babies and hypotrophic infants born at term. The significant increase in the case of underweight neonates of the disperse type of allantochorial vasculature does not suggest any significant relations to either lower weights of placenta or lower weights of newborn infants within the individual classification groups. There is no increase in the number of marginal-velamentous attachments of umbilical cords in the case of underweight neonates. Also, reference is made to the limited importance of macroscopically determined placentary conditions to individual cases.
将常规临床条件下宏观测定的低体重新生儿（营养良好的早产儿和足月出生的低营养婴儿）的胎盘状况（胎盘重量、胎盘/婴儿体重指数、脐带附着类型和尿囊绒毛膜血管系统）与临床和既往史正常的足月出生的营养良好婴儿的胎盘状况进行比较。对于早产儿和足月出生的低营养婴儿，低体重新生儿的胎盘重量显著降低和胎盘/婴儿体重指数显著升高必须进行不同的评估。在尿囊绒毛膜血管系统呈分散型的低体重新生儿中，其显著增加并不表明在各个分类组内与胎盘重量降低或新生儿体重降低有任何显著关系。低体重新生儿脐带边缘-帆状附着的数量没有增加。此外，还提到了宏观测定的胎盘状况对个别病例的重要性有限。
