MORPHOLOGICAL CHANGES IN THE PLACEENTA DURING GESTATION WITH PREMATURE PLACENTAL REMOVAL

Gulchekhra Yeshtaevna Tastanova Tashkent State Dental Institute, Republic of Uzbekistan

Resume

Morphological studies of placentas of pregnant first-born women with complicated gestation were performed. During the formation of premature detachment of the normally located placenta, deep transformations were revealed, both in the villous tree and in the vessels. Already in terms of 22-28 weeks of gestation in the placenta, a variant of pathological immaturity of terminal villi is formed against the background of a decrease in the number of capillaries, syncytial nodes are detected, which indicates an increase in hypoxia. It was found that at the end of the 3rd trimester, the placenta shows a decrease in the density and differentiation of decidual cells, incomplete replacement of the endothelium of the spiral arteries, a smaller number of Mature terminal villi, and the predominance of deformed villi, which indicates a violation of the dynamics of the formation of normal structural and functional relationships in the mother-placenta-fetus system, and, as a result, leading to placenta detachment.

Key words:  morphology, placenta, premature detachment of the placenta, terminal villi, hypoxia.
