Аневризмы аорты и её ветвей – наиболее грозное осложнение ДСТ, которое ограничивает продолжительность жизни пациентов, однако этот симптом вызывает меньше всего жалоб и долгое время остаётся нераспознанным. В настоящей работе представлен случай семьи с необычным сочетанием генетических и средовых факторов риска разрыва аорты в нескольких поколениях, что привело к накоплению внезапных смертей в двух поколениях и необходимости выполнения высокорисковой хирургии в третьем. В статье обсуждается тактика медико-генетического консультирования семей с синдромом Лойеса-Дитца, значение своевременной ДНК-диагностики, хирургических методов лечения и профилактики жизнеугрожающих осложнений.</p></abstract><trans-abstract xml:lang="en"><p>Connective tissue disorders (CTD) is a group of common hereditary diseases that occur in aa population of at least 1:2000 of the population, including at least 200 nosological forms. The most serious CTD complication is aneurysms of the aorta and its branches, which reduces patients’ life expectancy. Аneurysms usually do not cause complaints and remain unrecognized for a long time. This publication presents a family case of Loyes-Dietz syndrome with an unusual combination of genetic and environmental risk factors for aortic rupture in several relatives, which led to an accumulation of sudden deaths in two generations and the need for high-risk surgery in the third one. The article discusses the tactics of medical and genetic counseling for families with Loyes-Dietz syndrome, the importance of timely DNA diagnostics, surgical methods of treatment, and prevention of life-threatening complications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дисплазии соединительной ткани</kwd><kwd>аневризма восходящей аорты</kwd><kwd>расслоение аорты</kwd><kwd>TGFBR1</kwd><kwd>синдром Лойеса-Дитца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>connective tissue dysplasia</kwd><kwd>aortic dissection</kwd><kwd>ascending aortic aneurysm</kwd><kwd>TGFBR1</kwd><kwd>Loyes-Ditz syndrome</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке исследовательского проекта FURG-2023-0008</funding-statement><funding-statement xml:lang="en">The work was supported by research projects FURG-2023-0008.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Faggion Vinholo T., Brownstein A.J., Ziganshin B.A., et al.
