Timely diagnosis is even more complicated when there is a combination of both uterine and ectopic localization of the ovum. The article describes the clinical observation of heterotopic pregnancy, features of the clinical picture, diagnostic search and treatment strategy. The possibility of preservation of intrauterine pregnancy after surgical removal of a pathologically located second fertilized ovum has been shown. The patient was admitted to the gynecological department with complaints of bleeding from the genital tract against the background of delayed menstruation. An ultrasound examination revealed the presence of dichorionic diamniotic twins, with one fertilized egg localized in the interstitial part of the fallopian tube stump. Surgical removal of the stump with the fertilized egg was performed. The intrauterine pregnancy was preserved. Thus, with timely diagnosis of heterotopic pregnancy and adequate tactics, it is possible to maintain intrauterine pregnancy.</p></abstract><trans-abstract xml:lang="ru"><p>Приведено клиническое наблюдение сочетания маточной и внематочной беременности после экстракорпорального оплодотворения. Было проведено оперативное удаление культи маточной трубы с беременностью в истмическом отделе с сохранением маточной беременности у пациентки, перенесшей тубэктомию слева по поводу непроходимости маточной трубы при подготовке к программе ВРТ и тубэктомию справа в связи с последующей трубной беременностью. Показано, что при динамическом наблюдении возможно родоразрешение при доношенном сроке гестации. Использованы данные медицинских документов наблюдения пациентки в амбулаторных и стационарных условиях, в том числе результаты лабораторных, инструментальных, гистологических методов исследования. Получено информированное согласие пациентки для публикации результатов наблюдения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Heterotopic pregnancy</kwd><kwd>surgical treatment</kwd><kwd>prolongation of intrauterine pregnancy</kwd><kwd>in vitro fertiliza-tion</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Гетеротопическая беременность</kwd><kwd>оперативное лечение</kwd><kwd>пролонгирование маточной беременности</kwd><kwd>экстракорпоральное оплодотворение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Mullany K., Minneci M., Monjazeb R., C Coiado O.
