of arterial thrombosis with a thrombus that had atypical composition due to profound pathological changes in the cellular and protein composition of the blood.</p> <p><bold>Methods.</bold> Scanning electron microscopy of an ex vivo thrombus extracted from the common femoral artery.</p> <p><bold>Results.</bold> In the absence of platelets and leukocytes there was a significant prevalence of fibrin over other blood components in all layers of the arterial thrombus. There were no morphological signs of intravital contraction (retraction) characteristic for thrombi: single erythrocytes were not exposed compressive deformation, redistribution of fibrin and platelets within the thrombus toward the periphery. Formation of the atypical arterial thrombus in the vessel with atherosclerotic vessel damage is probably due to association with severe hyperfibrinogenemia and thrombocytopenia.</p> <p><bold>Conclusion.</bold> The structure of a thrombus depends not only on its vascular location (arterial or venous), but also on the cellular and protein composition of the blood. These factors support diversification of antithrombotic therapy, considering composition and properties of thrombi irrespective of the place and hemodynamic conditions of their formation.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Описание случая артериального тромбоза с атипичным строением тромба, образованного вследствие глубоких патологических изменений клеточного и белкового состава крови.</p> <p><bold>Методы.</bold> Сканирующая электронная микроскопия прижизненного тромба, извлеченного из общей бедренной артерии.</p> <p><bold>Результаты.</bold> В структуре артериального тромба, извлеченного из общей бедренной артерии, обнаружено значительное преобладание фибрина при практически полном отсутствии тромбоцитов и лейкоцитов во всех слоях. Не обнаружены характерные для тромбов морфологические признаки прижизненной контракции (ретракции): единичные эритроциты не подверглись компрессионной деформации, отсутствовало перераспределение фибрина и тромбоцитов с их накоплением на периферии тромба. Образование атипичного артериального тромба в сосуде с атеросклеротическим повреждением сосудистой стенки обусловлено, вероятно, сочетанием выраженной гиперфибриногенемии и тромбоцитопении.</p> <p><bold>Выводы.</bold> Строение тромбов зависит не только от сосудистой локализации (артерия или вена), но и от клеточного и белкового состава крови. Данные обстоятельства диктуют диверсификацию антитромботической терапии с учетом состава и свойств тромба, независимо от места и гемодинамических условий его образования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>arterial thrombus</kwd><kwd>fibrin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>артериальный тромб</kwd><kwd>фибрин</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Shida Y., Rydz N., Stegner D., et al.
