В исследование включен 61 пациент с ГЦР: 41 пациент с развитием портального тромбоза (основная группа), и 20 пациентов – контрольная группа. Всем выполнялась МСКТ с внутривенным контрастированием с последующим анализом характера контрастирования образования.</p></sec><sec><title>Результаты</title><p>Результаты. Первый – “классический” паттерн накопления контрастного вещества с пиком в артериальную фазу наблюдался у 2 (5%) пациентов с ГЦР, осложненным портальным тромбозом, и у 10 (50%) пациентов без тромбоза (p &lt; 0,01). Второй паттерн – гиперваскулярное контрастирование с пиком, смещенным во времени в сторону портальной фазы, и замедлением выведения контрастного вещества отмечен у 14 (34%) пациентов основной и 10 (50%) пациентов контрольной группы (p = 0,4). Третий и четвертый паттерны определялись только у пациентов с портальным тромбозом. При третьем – негомогенность контрастирования паренхимы печени в бассейне тромбированной вены без формирования отчетливого узла (17 пациентов (41%), p &lt; 0,01). При четвертом – накопление контрастного вещества в артериальную и портальную фазы только в узкой полоске на периферии узла, в центре – незначительное, в отсроченную фазу (8 пациентов (20%), p = 0,072).</p></sec><sec><title>Заключение</title><p>Заключение. Портальный тромбоз, осложняющий течение ГЦР, значительно изменяет паттерн контрастирования опухоли, что должно учитываться при анализе изображений во избежание диагностических ошибок.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. To study contrast enhancement patterns of hepatocellular carcinoma (HCC) in cases with portal thrombosis and without it.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 61 consecutive patients with HCC were included in the study and divided into two groups: 41 patient with portal vein thrombosis (main group) and 20 patients without thrombosis (control group). Each patient underwent a abdominal CE MDCT for the analysis of the lesion contrast enhancement.</p></sec><sec><title>Results</title><p>Results. The 1st – “classic” – contrast enhancement pattern with a peak at arterial phase was observed in 2 (5%) patients with HCC complicated by portal thrombosis and in 10 (50%) patients without thrombosis (p &lt; 0.01). The 2nd – “hypervascular” pattern with a peak shifted in 60–120s after contrast agent administration and no wash out was observed in 14 (34%) patients in the main group and in 10 (50%) patients in the control group (p = 0.4). The 3rd pattern – inhomogeneous contrast enhancement of liver parenchyma in the territory of thrombosed vein without visible tumor was discovered in 17 (41%) cases (p &lt; 0.01). The 4th pattern – peripheral enhancement in arterial and portal phase with insignificant central enhancement in delayed phase was visualized in 8 cases (20%, p = 0.072).</p></sec><sec><title>Conclusion</title><p>Conclusion. Portal thrombosis, which complicates the course of HCC, significantly changes the patterns of tumor’s contrast enhancement. This should be taken into account when image analysis to avoid diagnostic errors.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гепатоцеллюлярный рак</kwd><kwd>портальный тромбоз</kwd><kwd>паттерн контрастирования</kwd><kwd>пик контрастного усиления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hepatocellular cancer</kwd><kwd>portal thrombosis</kwd><kwd>contrast pattern</kwd><kwd>peak contrast enhancement</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">NCCN Clinical Practice Guidelines in Oncology.
