Ultrasound diagnosis of endometritis: hemodynamic features of the uterus

Abstract

Objective.To determine the characteristics of hemodynamics of the uterus with endometritis.Material and methods.A retrospective analysis of 420 patients of reproductive age (19–53 years old) diagnosed with endometritis. The comparison group consisted of 323 women aged 17–52 without gynecological pathology.Blood flow indicators in the uterine arteries, such as maximum systolic, end-diastolic, and average blood flow velocity (Vmax, Vmin, Vmean), were estimated, and an arterial perfusion index (API) was calculated. With 3D reconstruction of the uterus in angioregime, a vascularization index (VI), a flow index (FI) and a vascular flow index (VFI) of the uterus and endometrium were obtained.Result.An increase in Vmax, Vmin, Vmean, as well as VI, VFI of the uterus and VI, FI and VFI of the endometrium in the early and middle proliferative phase of the cycle. API had monotonous values, but it should be taken into account in conjunction with VI.Conclusions.Echography combined with color mapping, spectral Doppler graphics and vascularization index determination using 3D in angio mode is a highly effective method for the diagnosis of endometritis. Characteristic changes in hemodynamics in endometritis manifest as a violation of the venous outflow in the uterus and, especially, in the endometrium, in the presence of hypervascu larization according to data VI in the aggregate of regulatory or reduced indicators of API.

“…(2020) назвали скорректированным объемом эндометрия [30]. Этот параметр существенно снижает потенциальную разницу объема эндометриальной ткани в зависимости от объема матки у каждой конкретной женщины, что позволяет не только выбрать более адекватные пороговые значения для оценки рецептивности эндометрия, но и определить степень миометральной инвазии карциномы [27], а также выявить морфологический тип хронического эндометрита [32].…”
