Placental morphology – from theory to practice

The article provides a review of the literature on modern studies macroscopic and microscopic changes in placenta cases complicated childbirth diseases newborn. From clinical point view, values ​​of such indicators as length, tortuosity umbilical cord, its entry into are indicated. In particular, influence length cord course was considered – from an increased frequency birth children with low Apgar score short to increase risk entanglement, prolapse, true knot long cord. explains reasons for formation data types impact labor. weight is both terms absolute performance new perspectives assessment placental-fetal ratio. dynamics progression gestational period presented, well effect decrease further development diabetes mellitus hypertension mother. researches that provide rope findings placental infarctions retroplacental hematomas analyzed. Acute subacute infarction, differences between hematoma clinically expressed premature abruption, described. processes histological accompany maturation chorionic villi, typical manifestations insufficient remodeling spiral arteries, which, according concepts, basis most complications, considered. A concept Ukrainian resources, “villi maturity index”, which defined ratio number vascular syncytial membranes 1 cm2 studied area ​​the sample thickness these membranes, presented. It known significant this indicator due their pregnancies by severe preeclampsia mellitus.
