An ectopic pregnancy is a complication that occurs in approximately 1–2 % of all pregnancies and can cause morbidity and mortality in women of childbearing age. Identification of potential risk factors for the diagnosis of ectopic pregnancy remains an urgent, incompletely studied question.</p> <p><bold>Materials and methods.</bold> A descriptive exploratory study was conducted on the basis of the City Clinical Hospital named after M.A. Tverie, Perm. The objects of the study were 20 women with tubal pregnancy. All patients were admitted to the gynecological unit of the clinic with a diagnosis of “progressing tubal pregnancy”, for which tubotomy with laparoscopic access was performed that allowed to preserve the integrity of the material. Besides traditional histological study, in all cases a chromosome microarray analysis of the fetal egg was performed.</p> <p><bold>Results</bold>. In addition to routine histological study, in all cases of the analyzed group, a chromosome microarray analysis of the ovum material was carried out. It turned out that in one case, in a 28-year-old patient with a five-week tubal frozen pregnancy a complex chromosome imbalance was found: three copies of 1–6, 8–22 and X chromosomes and four copies of chromosome 7, molecular karyotype (according to ISCN 2016): arr (1–6. 8–22, X) x3, (7) x4.</p> <p><bold>Conclusions. </bold>Despite the fact that genetic breakdowns are uncontrollable factors and it is not possible to directly influence them, the search for possible mechanisms leading to them is promising.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Определить значение хромосомных аберраций при внематочной беременности. Внематочная беременность является осложнением, которое встречается примерно в 1–2 % всех беременностей и может являться причиной заболеваемости и смертности женщин фертильного возраста. Выявление потенциальных факторов риска для диагностики внематочной беременности остается актуальным, не полностью изученным вопросом.</p> <p><bold>Материалы и методы. </bold>Проведено поисковое описательное исследование на базе ГКБ им. М.А. Тверье г. Перми. Объектами исследования послужили 20 женщин с трубной беременностью. Все пациентки поступили в гинекологическое отделение клиники с диагнозом «прогрессирующая трубная беременность», по поводу чего выполнялась операция туботомии лапароскопическим доступом, что позволило сохранить целостность материала. Кроме традиционного гистологического исследования, во всех случаях был проведен хромосомный микроматричный анализ плодного яйца.</p> <p><bold>Результаты. </bold>В дополнение к рутинному гистологическому исследованию во всех анализируемых случаях проведено хромосомное микроматричное исследование материала плодного яйца. Оказалось, что в одном случае у пациентки 28 лет при трубной замершей беременности в сроке 5 недель обнаружен сложный хромосомный дисбаланс: три копии 1–6, 8–22 и Х хромосом и четыре копии 7-й хромосомы, молекулярный кариотип (согласно ISCN 2016): arr(1-6,8-22,X)x3,(7)x4.</p> <p><bold>Выводы.</bold> Несмотря на то что генетические поломки относятся к неуправляемым факторам и напрямую воздействовать на них не представляется возможным, перспективным является поиск возможных механизмов, приводящих к ним.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ectopic pregnancy</kwd><kwd>chromosomal abnormalities</kwd><kwd>microarray analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>внематочная беременность</kwd><kwd>хромосомные аномалии</kwd><kwd>микроматричный анализ</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Ectopic (ectopic) pregnancy.
