Specific features of human placenta anatomy in pregnancy achieved by in vitro fertilization

Abstract

Aim to evaluate the qualitative and quantitative morphological characteristics of placentas of pregnant women after in vitro fertilization (IVF) registered in the prenatal period and after birth. Material and methods. The retrospective study of medical records of pregnant and puerperia women focused on the chorion and placenta parameters registered by ultrasound examinations in the I, II, III trimesters. The patients' inclusion criteria were singleton pregnancy and birth at 37-41 weeks' gestation. The types of assisted reproductive technologies and delivery were not specified in this study. The patients were divided into 2 groups according to their age: 1 Group I period of adulthood, 2 Group II period of adulthood. The postpartum placenta morphometry included registration of shape, diameter, weight, thickness of the placenta, the place of attachment and length of the umbilical cord, the type of vessels branching. Results. 1. The ultrasound characteristics of the placenta anatomy during pregnancy achieved by IVF are generally normal and do not have specific features. The pathological location of the chorion in the uterine cavity in the first trimester of pregnancy is characterized by a risk factor the older age group. The weight of the placenta during full-term pregnancy after in vitro fertilization is higher than normal, its average area is larger due to a decrease in thickness. A large proportion of pathological (sheath) attachment of the umbilical cord can lead to more frequent complications of pregnancy acute placental insufficiency.
