Сообщается о мужчине, у которого в возрасте 30 лет развился ИИ в бассейне левой среднемозговой артерии. Диагностическое исследование позволило установить, что развитию ИИ способствовала тромбофилия, обусловленная сочетанием полиморфных вариантов генов фибриногена (G-455A (G-467A)), метилентетрагидрофолатредуктазы (C677T). Таким образом, наследственная тромбофилия явилась фактором риска развития ИИ у больного в молодом возрасте, поэтому при отсутствии традиционных факторов риска развития ИИ необходимо проведение генетического анализа на тромбофилию.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction.

A case is presented of a man, aged 30, who developed an ischemic stroke in the basin of the left medial artery. A diagnostic study revealed that the development of the ischemic stroke was facilitated by thrombophilia caused by a combination of polymorphic variants of the fibrinogen genes (G-455A(G-467A)) and methylenetetrahydrofolate reductase (C677T). Thus, hereditary thrombophilia was a risk factor for the development of ischemic stroke in the patient at a young age. Therefore, in the absence of traditional risk factors for the development of ischemic stroke, a genetic analysis for thrombophilia is necessary.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>наследственные тромбофилии</kwd><kwd>полиморфизм генов</kwd><kwd>тромбоз</kwd><kwd>факторы тромбогенного риска</kwd><kwd>ишемический инсульт</kwd><kwd>антикоагулянты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hereditary thrombophilia</kwd><kwd>thrombosis</kwd><kwd>ischemic stroke</kwd><kwd>thrombogenic risk factors</kwd><kwd>hemostasis</kwd><kwd>anticoagulants</kwd><kwd>gene polymorphism</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">Ишемический инсульт и транзиторная ишемическая атака у взрослых.
