胎盘的平均表面形状是圆形的，常见的形状异常与血管异常和胎盘功能效率降低有关。一种长期存在的方法是将形状描述为椭圆形，并通过“长度”和“宽度”来量化它们。我们在两个队列中测试了这一描述：国家围产期合作项目和妊娠、感染和营养研究。我们的结论是，将胎盘形状量化为椭圆形是不明确且有问题的。胎盘的“宽度”应解释为两种不同测量值的组合：胎盘大小和胎盘表面的不规则性。它没有内在的功能意义。
The mean surface shape of placenta is round and common abnormalities of shape are associated with vascular abnormalities and reduced placental functional efficiency. A long-standing approach is to describe shapes as elliptic, and to quantify them by “length” and “breadth”. We test this description in two cohorts: National Collaborative Perinatal Project and Pregnancy, Infection and Nutrition Study. We conclude that quantifying placental shape as elliptic is ambiguous and problematic. The “breadth” of the placenta should be interpreted as a combination of two different measurements: placental size and irregularity of the placental surface. It has no intrinsic functional significance.
