The Northwestern twin chorionicity study: testing the ‘placental crowding’ hypothesis

Objective: To evaluate the relation between placental proximity and frequency of birth weight discordance and small-for-gestational age (SGA) infants.

Study design: Retrospective three-tier chorionicity analysis of 1155 twin placentas comparing birth weight characteristics of the twins in different placental types.

Results: Dichorionic-separate, but not dichorionic-fused twins, are heavier than monochorionic-diamniotic and monoamniotic twins (2376±721 vs...
