Проведена 4D КТ-ангиография интракраниальных артерий 3 пациентам с аневризмами различных локализаций без разрыва. Прослежено контрастирование аневризм в артериальной, венозной и отсроченной фазах введения контрастного вещества. В венозной фазе отмечено повторное контрастирование аневризматического мешка на 27-29с от введения контрастного вещества в каждом из 3 случаев. Исходя из существующих теорий формирования и роста аневризм, такая особенность контрастирования, более вероятно, связана с проявлением теории «медленного потока». Для подтверждения этого предположения необходимо дальнейшее исследование.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to study the hemodynamic features in intracranial aneurysms. Material and methods: we performed 4D CT-angiography at 3 patients with unruptured aneurysms of various localization and size. Results: The aneurysm contrast was observed in arterial, venous and delayed phases after contrast injection. We noted the repeated contrast of aneurismal sac in venous phase (on 27-29 sec from contrast injection) in each of three presented clinical cases. Conclusion: The noted feature of aneurysm contrast (repeated contrast in venous phase) is much more likely related to so-called “theory of slow blood flow” which is one of the modern theories for explanation of aneurysm occurrence and their growth. However the further investigation is necessary to confirm this suggestion.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>intracranial aneurysm</kwd><kwd>hemodynamic</kwd><kwd>4D CT-angiography</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">Крылов В.В., Годков И.М.
