The structure of the the umbilical cord during normal and postterm pregnancy

Abstract

Background: Excessive pregnancies are a major concern in obstetric practice, leading to birth defects, perinatal mortality, and postpartum hemmorrhage. Our researchers estimate that postterm accounts for 6 percent of all births. Objective: Compare the length, attachment, and microstructure of the umbilical cord of a normal or more pregnant mother. Materials: Urguu, Khuree, Amgalan maternity hospitals, and Maternal and Child Health National Center normal pregnancy 381-6-401-6 mothers’ who were treated in 2017-2018 and 1061 mothers who were over 41 weeks pregnant were used. Method: The umbilical cord is defined in four ways: in the center, at the edges, in the midlle, on the film. The microstructure of the umbilical cord was determined using Hematoxylin Eosin and Trichrome Masson Van Ginson dyes. Results: The 695 cord lengths of the normal openings surveyed were 56.47±0.334 cm during the 27.00-90.00cm competition, and the 366 cord lengths ranged from 33.00-92.00cm to 57.667±0.456cm, p<0.05.There is no statistically significant difference in umbilical cord fixation. During normal pregnancy, the endothelial cells of the umbilical artery are arranged in many rows on the basement membrane in a cross-section, and its nuclei are visible from tor to bottom. During pregnancy, it is observed that one side of the ubilical artery wall becomes focal, the connective tissue fibers thicken, and the smooth muscle fibers in the muscular layer from layered structure. During normal pregnancy, squamous endothelial cells sit parallel to the basement membrane in the cross-section of the venous vessel, and a thin layer of thin endothelium beneath it is observed. During overexertion, the venous musculature becomes sparse, and fluffy connective tissue layers become empty. Conclusion: There is a real difference in the length and microstructure of the umbilical cord in normal and more pregnant women, there is no real difference in the position of the umbilical cord.
