Выявить частоту тромбоза глубоких вен (ТГВ), установленного методом компрессионного дуплексного сканирования в учреждениях первичного звена здравоохранения в предпандемийный период и во время пандемии новой коронавирусной инфекции (COVID-19 (COronaVIrus Disease 2019)).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведен ретроспективный анализ результатов 1492 дуплексных ультразвуковых исследований в 2018г и 1710 исследований в 2020-2021гг у пациентов с подозрением на ТГВ нижних конечностей (НК). Исследования проводились в 4-х медицинских учреждениях первичного звена здравоохранения в разных городах Республики Узбекистан. Каждому пациенту проводилось дуплексное сканирование глубоких вен НК. Большинство пациентов имели жалобы (отек, боль в ногах) (симптомные пациенты), некоторые прошли профилактический скрининг перед различными оперативными вмешательствами и не имели жалоб (бессимптомные пациенты).</p></sec><sec><title>Результаты</title><p>Результаты. По полученным данным частота ТГВ статистически значимо возросла во время пандемии — от 3,9 до 15,1% (χ2=113,23, p&lt;0,001). В период пандемии отмечалась тенденция к относительному увеличению частоты ТГВ НК среди пожилых и молодых людей — на 8,7 и 3,8%, соответственно (χ2=1,66, р=0,19 и χ2=0,64, р=0,42, соответственно). Зависимости частоты ТГВ НК от пола пациента не обнаружено (χ2=0,02, r=0,9).</p></sec><sec><title>Заключение</title><p>Заключение. Результаты проведенного исследования показали увеличение частоты выявления ТГВ НК в период пандемии COVID-19. Необходимы дальнейшие клинические исследования для анализа частоты ТГВ НК в этот период.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To identify the incidence of deep vein thrombosis (DVT) as determined by compressive duplex ultrasound in primary health care facilities before and during the pandemic of a coronavirus disease 2019 (COVID-19).</p></sec><sec><title>Material and methods</title><p>Material and methods. This retrospective analysis of 1492 duplex ultrasound examinations in 2018 and 1710 examinations in 2020-2021 in patients with suspected lower limb DVT was performed. The studies were carried out in 4 primary health care institutions in different cities of the Republic of Uzbekistan. Each patient underwent duplex ultrasound of lower limb deep veins. Most patients had complaints (swelling, leg pain) (symptomatic patients), while some individuals underwent preventive screening before various surgical interventions and had no complaints (asymptomatic patients).</p></sec><sec><title>Results</title><p>Results. According to the data obtained, the prevalence of DVT increased significantly during the pandemic — from 3,9 to 15,1% (χ2=113,23, p&lt;0,001). During the pandemic, there was a trend towards a relative increase in lower limb DVT among the elderly and young people — by 8,7 and 3,8%, respectively (χ2=1,66, p=0,19 and χ2=0,64, p=0,42, respectively). No dependence of the prevalence of lower limb DVT on the sex was found (χ2=0,02, r=0,9).</p></sec><sec><title>Conclusion</title><p>Conclusion. The study results showed an increase in the prevalence of lower limb DVT during the COVID-19 pandemic. Further clinical studies are needed to analyze the lower limb DVT during this period.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тромбоз глубоких вен нижних конечностей</kwd><kwd>дуплексное сканирование</kwd><kwd>пандемия</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lower limb deep vein thrombosis</kwd><kwd>duplex ultrasound</kwd><kwd>pandemic</kwd><kwd>COVID-19</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">Подлипаева А.
