Characteristics of uterine blood supply in women with chronic endometritis depending on the duration of infertility

Objective. To assess the hemodynamics of the uterus, including the endometrium, in women with chronic endometritis depending on the duration of infertility. Materials and methods. This was a retrospective analysis of an ultrasound study of 581 reproductive-aged women suffering from infertility and diagnosed with endometritis. All women were divided into groups according to the duration of infertility: less than 2 years, from 2 to 5 years and more than 5 years. In the uterus and endometrium, the vascularization index (VI), the flow index (FI), and the vascular-flow index (VFI) were evaluated. Dopplerography of the uterine artery showed the arterial perfusion index (API), which reflects perfusion of 1 cm3 of the uterus. Results. According to the data of VI, FI and VFI, vascularization of the uterus and endometrium decreased not only in phase I, but also in phase II along with the increase in the duration of infertility. Arterial perfusion of the uterus decreased in phase I. There were no significant changes in the maximum blood flow rate (Vmax), pulsation index (PI), and resistance index (RI) in the groups. Conclusion. The increase in the duration of infertility is accompanied by a decrease in vascularization not only of the endometrium, but also of the myometrium, as well as a decrease in arterial blood flow. © A group of authors, 2020
