У женщин описываются анатомические особенности аневризмы инфраренального сегмента аорты, отмечается более тяжелое течение аневризматического и окклюзионно-стенотического поражения аорто-подвздошного сегмента. Гендерные особенности морфологических изменений стенки аорты изучены недостаточно.</p><p>Цель – изучить гендерные особенности структурных изменений стенки брюшной аорты у больных с аневризмой и окклюзионно-стенотическим поражением аорто-подвздошного сегмента.</p></sec><sec><title>Методы и материалы</title><p>Методы и материалы. Изучены 96 биоптатов стенки брюшной аорты 71 пациента с поражением аорто-подвздошного сегмента (23 женщины, 48 мужчин). Анализировали ряд морфологических характеристик и экспрессию матриксной металлопротеиназы 9 (MMP-9). Полученные данные обрабатывали статистически.</p></sec><sec><title>Результаты</title><p>Результаты. Клеточный инфильтрат в адвентиции и склероз в медии более выражены при аневризматическом, чем при окклюзионно-стенотическом поражении, различия в степени фиброза зарегистрированы только у мужчин. Вне зависимости от пола пациентов клеточная инфильтрация в адвентиции более выражена в области аневризматического мешка, чем в области шейки аневризмы, другие изменения стенки аорты в зоне шейки и тела аневризмы носят однотипный характер. В шейке аневризмы экспрессия ММР-9 в адвентиции у женщин выше, чем у мужчин. Экспрессия MMP-9 в медии и адвентиции у мужчин выше при аневризматическом, чем при окклюзионно-стенотическом поражении. У мужчин с аневризмой, в отличие от женщин, практически все показатели глубины перестройки стенки аорты и экспрессии ММР-9 коррелируют друг с другом.</p></sec><sec><title>Заключение</title><p>Заключение. Гендерные особенности морфологических изменений стенки аорты и степени их сопряженности могут обусловливать различия в анатомии и течении аневризматического и окклюзионно-стенотического поражения аорто-подвздошного сегмента у больных разного пола. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Evidence exists that infrarenal aortic aneurisms and aortoiliac occlusive disease in women are different than in men in terms of anatomical features and more severe clinical course. Gender differences in histopathology of abdominal aorta are not fully studied.</p><p>The objective was to study gender based differences in histopathology of abdominal aorta in patients with aortic aneurisms and aortoiliac occlusive disease.</p></sec><sec><title>Methods and materials</title><p>Methods and materials. The study included 96 biopsy specimens from 71 patients with aorto-iliac lesions (23 women and 48 men). A number of morphological characteristics and expression of matrix metalloproteinase 9 (MMP-9) were analyzed. The data obtained were processed statistically.</p></sec><sec><title>Results</title><p>Results. Adventitial infiltrate and medial sclerosis are more intense in the aneurysm than in occlusive-stenotic lesions, differences in the grade of fibrosis were proven only in men. Regardless of the patients’ gender, adventitial infiltration is denser in the aneurysmal body than in the neck; other changes in the anatomic parts of the aneurysm are similar. MMP-9 expression in the adventitia in the aneurysmal neck is higher in women, than in men. MMP-9 expression in the media and adventitia is higher in men with aneurysm, then with occlusive or stenotic lesion. Almost all indices of the aortic wall remodeling and MMP-9 expression correlate with each other in men with the aneurysm, in contrast to women.</p></sec><sec><title>Conclusion</title><p>Conclusion. Gender based features in histopathology of abdominal aorta and the degree of their correlation may determine differences in the anatomy and course of abdominal aortic aneurysm and aortoiliac occlusive disease in women and men. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>брюшная аорта</kwd><kwd>подвздошные артерии</kwd><kwd>аневризма</kwd><kwd>атеросклероз</kwd><kwd>гендерные различия</kwd><kwd>женщины</kwd><kwd>морфология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>abdominal aorta</kwd><kwd>iliac arteries</kwd><kwd>aneurysm</kwd><kwd>atherosclerosis</kwd><kwd>gender differences</kwd><kwd>women</kwd><kwd>histopathology</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">Российский статистический ежегодник // Федеральная служба государственной статистики.
