[Doppler evaluation of blood flow in the umbilical artery when confronted with morphologic changes in human placenta of pregnancy complicated by diabetes]. / Dopplerowska ocena przeplywu krwi w tetnicy pepowinowej w konfrontacji ze zmianami morfologicznymi w lozysku ludzkim w ciazy powiklanej cukrzyca.

ABSTRACT

Doppler ultrasound velocimetry in umbilical artery was performed in 23 pregnant women in different classes of the diabetes. Results obtained were compared with the afterbirths' morphology. Strict correlation was found between arteries obliteration in the placenta and vascular resistance in higher classes of the diabetes. Normal structure of the villi with signs of their morphological maturity has basic influence on proper umbilical artery flow maintenance.
