Placental villous immaturity is chorionic villous development that is inappropriate for the gestational age.
It is associated with diabetes mellitus[1] and fetal death near term, i.e. intrauterine demise close to the normal gestational period.[2]
Pathology
[edit]Immature chorionic villi are larger and have more central blood vessels; thus, the diffusion distance for gas and nutrient exchange is larger and, therefore, placental function is impaired.
