WITH MILDLY LARGE VILLI AND FOCAL VILLOUS EDEMA, SEE COMMENT. | |||
- THREE VESSEL UMBILICAL CORD WITHIN NORMAL LIMITS. | |||

COMMENT: | |||
Large villi and villous edema are findings of placental villous immaturity; | |||
in this placenta, these changes are present but not well developed. | |||
Placental villous immaturity is most often associated with maternal diabetes. | |||
