ABSTRACT
The organometric and histometric parameters of vascular and stromal components were studied in 95 umbilical objects, by taking into account its segmental structure, the specific features of the course of pregnancy and labor. Umbilical samples were divided into 4 groups: 1) those in full-term pregnancy (a control group); 2) those in hypoplasia of Wharton's jelly; 3) those in cord entanglement around the neck; 4) those during elective cesarean section. The results of a study of the histotopographic features of the umbilical cord allow evaluation of the structural and functional status of umbilical circulation. Morphometric equivalents have been developed for umbilical cords with hypoplasia of Wharton's jelly, those with cord entanglement around the fetal neck and those during surgical delivery.

The morphology of the neonatal umbilical cord was studied in 23 women during elective surgical delivery and in 32 women during normal physiological delivery. Organ- and histometric indices were used. These included: length, weight, a linear weight unit; the average diameter of the umbilical cord, etc. The significant increase of organometric indices (a linear weight unit of weight, the average diameter of the umbilical cord) and histometric ones (a drastic venous lumen increase, a significant increase in the proportion of Wharton's jelly) document acute umbilical blood flow disorder in the absence of the conditions characteristic for normal delivery. Moderately pronounced edema of the umbilical cord peripheral layer emerges. A complex of morphofunctional umbilical cord changes during surgical delivery serves as predictor of neonatal respiratory distress syndrome.
