The placentas of 105 small-for-dates infants and 190 newborns of normal birth weight were investigated morphologically. Each of these two groups consists of premature newborns and mature newborns. Macroscopic and microscopic data were evaluated by means of a so called data bank. --The weight and the area of attachment were determined. The histologic findings were classified in two groups: 1. Disturbances of placental maturation, 2. Morphologic changes in consequence of reduced uteroplacental blood flow. A marked increase of hypoplastic placentas was found among immature and mature small-for-dates infants. Retarded placental maturity was found more frequently among mature small-for-dates infants then among prematures. Among these, placentas with signs of a reduced uteroplacental perfusion were found more frequently. --It is assumed that the pathogenetic course is different in placentas of premature and mature small-for-dates infants.
对105例小于胎龄儿和190例出生体重正常的新生儿的胎盘进行了形态学研究。这两组均由早产儿和足月儿组成。宏观和微观数据通过一个所谓的数据库进行评估。测定了胎盘重量和附着面积。组织学检查结果分为两组：1. 胎盘成熟障碍；2. 子宫胎盘血流减少导致的形态学改变。在未成熟和成熟的小于胎龄儿中，发育不全的胎盘明显增多。与早产儿相比，成熟小于胎龄儿中胎盘成熟延迟更为常见。其中，子宫胎盘灌注减少迹象的胎盘更为常见。据推测，早产和成熟小于胎龄儿胎盘的发病机制不同。
