Claims (1)

Способ выбора модели стента для процедуры стентирования церебральных артерий с аневризмой, включающий ввод данных об артерии; вычисление размера стента, основанное на данных выбранной артерии, содержащих проксимальный и дистальный диаметр, тип артерии; проверку доступности стента; выбор модели стента, основанный на размере и доступности стента; вывод данных о выбранной модели стента, отличающийся тем, что с помощью КТ-ангиографии определяется форма и размер церебральной аневризмы; с помощью экспериментальной установки происходит измерение скорости крови в индивидуализированной реалистичной модели аневризмы пациента со стентом и без стента, с помощью 3D лазерного допплеровского анемометра измеряются три компоненты скорости крови в сечениях модели пораженного церебрального сосуда; с помощью математического моделирования на основе разработанной авторами математической модели локальной гемодинамики церебральной артерии определяются изменения трех компонент скорости крови и давления в выбранной церебральной артерии при наличии различных моделей стентов; на основе рассчитанных гемодинамических параметров и пристеночного напряжения сдвига оцениваются изменения гемодинамики в области аневризмы пораженного сосуда, что позволяет повысить точность выбора модели стента для процедуры стентирования церебральных артерий с аневризмой.A method for selecting a stent model for a cerebral artery stenting procedure with aneurysm, comprising inputting artery data; calculating stent size based on data from a selected artery containing proximal and distal diameters, artery type; check stent availability; stent model selection based on stent size and availability; data output on the selected stent model, characterized in that the CT angiography determines the shape and size of the cerebral aneurysm; using an experimental setup, blood speed is measured in an individualized realistic model of a patient’s aneurysm with and without a stent; using the 3D laser Doppler anemometer, three components of the blood speed are measured in sections of the model of the affected cerebral vessel; using mathematical modeling on the basis of a mathematical model developed by the authors of the local hemodynamics of the cerebral artery, changes in the three components of the blood speed and pressure in the selected cerebral artery are determined in the presence of various stent models; Based on the calculated hemodynamic parameters and wall shear stress, hemodynamic changes in the aneurysm of the affected vessel are estimated, which improves the accuracy of the choice of stent model for the procedure for stenting cerebral arteries with aneurysm.
