В исследование включена 401 беременная женщина I триместра. Пациентки были разделены на основную группу (с перенесенным хроническим эндометритом в анамнезе) и группу сравнения (без указаний на хронический эндометрит). Оценивали показатели допплерометрии маточных артерий, рассчитывали ИАП матки как интегральный показатель артериального кровоснабжения. Анализ проводили отдельно для гестационных сроков 5–7+6, 8–10+6 и 11–13+6 нед беременности. Для межгрупповых сравнений использовали непараметрические методы с расчетом разности медиан и 95% доверительных интервалов. Прогностическую значимость показателей оценивали методом ROC-анализа.</p></sec><sec><title>Результаты</title><p>Результаты. Во всех гестационных сроках I триместра у пациенток основной группы выявлено снижение ИАП по сравнению с группой сравнения. Наиболее выраженные различия зарегистрированы в сроке 11–13+6 нед беременности, где ИАП демонстрировал наибольшую величину эффекта (AUC 0,92), превосходя таковую для скоростных показателей и индексов сосудистого сопротивления, и высокую прогностическую значимость в отношении неблагоприятных исходов первой половины беременности. Индексы сосудистого сопротивления (PI, RI) характеризовались меньшей устойчивостью различий и большей операторозависимостью по сравнению с ИАП.</p></sec><sec><title>Заключение</title><p>Заключение. ИАП матки является информативным интегральным показателем маточного кровоснабжения в I триместре беременности. Перенесенный хронический эндометрит ассоциирован со снижением ИАП и неблагоприятным профилем маточной гемодинамики. Полученные данные свидетельствуют о перспективности использования ИАП для оценки условий ранней плацентации и стратификации риска неблагоприятных исходов беременности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: To evaluate the usefulness of the uterine arterial perfusion index (API) and uterine artery Doppler parameters for assessing uterine blood supply in the first trimester of pregnancy in women with a history of chronic endometritis and to determine their prognostic value for adverse outcomes in the first half of pregnancy.</p></sec><sec><title>Material and methods</title><p>Material and methods. Pregnant women (401) in the first trimester were enrolled and divided into a main group (with a history of chronic endometritis) and a comparison group (without evidence of chronic endometritis). Uterine artery Doppler parameters were assessed, and the uterine arterial perfusion index was calculated as an integral measure of uterine arterial blood supply. Analyses were performed separately for gestational windows of 5–7+6, 8–10+6, and 11–13+6 weeks. Nonparametric statistical methods with median differences and 95% confidence intervals were used. Prognostic performance was evaluated using ROC analysis.</p></sec><sec><title>Results</title><p>Results. Across all first-trimester gestational windows, women in the main group demonstrated lower uterine arterial perfusion index values compared with the comparison group. The most pronounced differences were observed at 11–13+6 weeks of gestation, when API demonstrated the greatest magnitude of effect (AUC 0.92), exceeding that for velocity indicators and vascular resistance indices and high prognostic significance in relation to adverse outcomes in the first half of pregnancy. Resistance indices (PI, RI) were less consistent and more operator-dependent than the integral perfusion index.</p></sec><sec><title>Conclusion</title><p>Conclusion. The uterine arterial perfusion index is an informative integral parameter of uterine blood supply in the first trimester of pregnancy. A history of chronic endometritis is associated with reduced API and an unfavorable uterine hemodynamic profile. These findings support the potential use of API as a marker of early placentation conditions and for risk stratification of adverse pregnancy outcomes.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ультразвуковая диагностика</kwd><kwd>I триместр беременности</kwd><kwd>хронический эндометрит</kwd><kwd>маточные артерии</kwd><kwd>допплерометрия</kwd><kwd>индекс артериальной перфузии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ultrasound diagnostics</kwd><kwd>chronic endometritis</kwd><kwd>first trimester of pregnancy</kwd><kwd>uterine arteries</kwd><kwd>Doppler ultrasound</kwd><kwd>arterial perfusion index</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Espinoza J., Romero R., Mee Kim Y. et al.
