МСКТ с внутривенным болюсным контрастированием выполнена 645 пациентам с различными заболеваниями органов брюшной полости и забрюшинного пространства. Информация, полученная после анализа диагностических изображений, сопоставлялась с клиническими симптомами, а в отдельных случаях – с интраоперационными данными.</p></sec><sec><title>Результаты</title><p>Результаты.В исследуемой группе у 71 (11%) больного при МСКТ-исследовании были выявлены предпосылки для возникновения компрессионных синдромов, из них у 11 (15%) отмечены соответствующие клинические признаки. Хирургическое лечение было проведено в 3 случаях, в остальных 8 наблюдениях оказалось эффективным консервативное лечение.</p></sec><sec><title>Заключение</title><p>Заключение. У 11 (1,7%) из 645 пациентов, обследованных с помощью МСКТ по поводу различных заболеваний органов брюшной полости и забрюшинного пространства, были диагностированы компрессионные синдромы.
