In pregnant women it occurs mainly in the first trimester and its rate does not exceed 6 cases per 10,000 pregnancies, which is 10–22% of the total number of appendiceal torsions. Despite the low incidence of this pathology during pregnancy, labor and postpartum, ovarian torsion may cause unfavorable perinatal (ante/intrapartum fetal death) and maternal outcomes (obstetric peritonitis); its diagnosis is difficult as the clinical picture of ovarian torsion during gestation is asymptomatic and nonspecific.</p> <p><bold>Case</bold><bold> </bold><bold>report</bold><bold>:</bold> The article presents a clinical case of ovarian torsion during the first stage of term labor. A 36-year-old primiparous female patient had uterine contractions accompanied by persistent pain in the left lateral and subcostal regions, nausea and single vomiting within two hours after admission to the maternity ward. The laboratory examination showed only an increase in C-reactive protein up to 24 mg/L. The ultrasound examination revealed a mass in the left ovary, which suggested an acute abdomen associated with ovarian torsion. The patient had an emergency operative delivery; the exploration of the abdominal cavity confirmed the diagnosis.</p> <p><bold>Conclusion</bold><bold>:</bold> Ovarian torsion in labor is a rare emergency situation in obstetrics and it is characterized by a subtle clinical picture, low informative value of laboratory and ultrasound data. A proper history taking (information about the ovarian mass that existed before pregnancy and was described by ultrasound in the first half of pregnancy) and high qualification of doctors who knew about the possibility of ovarian torsion with the mass inside the ovary during pregnancy and in labor made it possible to make a timely diagnosis and choose the right tactics.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность:</bold> Беременность и роды являются фактором риска перекрута яичника. Частота данной патологии во время беременности, чаще всего в I триместре, не более 6 случаев на 10 000 беременностей, что составляет 10–22% от общего числа перекрутов придатков. Несмотря на низкую частоту развития данной патологии во время беременности, в родах и послеродовом периоде, клиника перекрута яичника в период гестации малосимптомна и малоспецифична, что вызывает трудности диагностики, но в тоже время перекрут яичника может быть причиной неблагоприятных перинатальных (анте/интранатальная гибель плода) и материнских исходов (акушерский перитонит).</p> <p><bold>Описание: </bold>Представляем собственный клинический случай перекрута яичника в первом периоде родов при доношенной беременности. У первородящей пациентки, 36 лет, в течении 2 ч после поступления в родовое отделение к схваткообразным болям присоединились постоянные боли в левой боковой и подреберной областях, появилась тошнота и однократная рвота. При лабораторном обследовании отмечено только повышение С-реактивного белка до 24 мг/л. При ультразвуковом обследовании обнаружено образование левого яичника, что навело на мысль об остром животе, связанном с перекрутом яичника. Пациентка была экстренно родоразрешена оперативным путем; при ревизии брюшной полости диагноз был подтвержден.</p> <p><bold>Заключение: </bold>Перекрут яичника в родах – редкая ургентная акушерская ситуация со стертой клинической картиной, малой информативностью лабораторных и ультразвуковых данных. Своевременно поставить диагноз и выбрать правильную тактику позволили хорошо собранный анамнез роженицы (информация об образовании яичника, существовавшего до беременности и описанного по УЗИ в первой половине беременности), высокая квалификация врачей, владеющих знаниями о возможности перекрута яичника с наличием образования в нем в период беременности и в родах.</p></trans-abstract><kwd-group xml:lang="en"><kwd>first stage of labor</kwd><kwd>acute abdomen</kwd><kwd>ovarian torsion</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>первый период родов</kwd><kwd>острый живот</kwd><kwd>перекрут яичника</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена без спонсорской поддержки</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Малышкина А.И., Батрак Н.В.
