This study found that women with endometritis exhibit increased uterine and endometrial blood flow velocities and vascularization, particularly in the proliferative phase, indicating a violation of venous outflow alongside hypervascularization.

The study retrospectively analyzed uterine hemodynamic parameters on ultrasound in 420 reproductive-age patients (19–53 years) diagnosed with endometritis, using a comparison group of 323 reproductive-age women without gynecologic pathology. Using transvaginal 3D angiography and Doppler, the authors quantified uterine artery flow velocities (Vmax, Vmin, Vmean), arterial perfusion indices (IAП), and 3D vascular indices (vascularization index VI, flow index FI, and combined vascularization-flow index VFI) for both uterus and endometrium. They found increased Doppler velocities and higher VI/VFI (uterus) and VI/FI/VFI (endometrium) in the early and mid-proliferative cycle phases, with IАП showing monotonic values that should be interpreted together with VI; a key caveat is the retrospective design and restriction to patients already diagnosed with endometritis. The paper is relevant to endometriosis because it focuses on uterine/endometrial vascular changes assessed by ultrasound Doppler techniques, which are often evaluated in endometriosis-related endometrial inflammatory and vascular alterations, though it does not specifically study endometriosis.

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.
