Численное моделирование течения крови в аорте с локальным сужением артериального протока

Abstract

В работе выполнено численное моделирование течения крови в аорте с локальным сужением артериального протока. Построены упрощенные модели аорты: на основе снимков компьютерной томографии, при расширении минимального диаметра области сужения в 1.5 раз, а также модель здоровой аорты. В работе представлен анализ гемодинамических изменений в потоке, связанный с коррекцией патологии, как в ньютоновской постановке, так и с учетом реальных свойств крови (модель вязкости Карро-Яшида). На основе результатов скорректированы рекомендации для процедуры лечения коарктации аорты с помощью метода баллонной ангиопластики.

In this work, numerical modeling of blood flow in the aorta with local narrowing of the arterial duct was performed. Simplified models of the aorta were built: based on computed tomography images, with the expansion of the minimum diameter of the narrowing area by 1.5 times, as well as a model of a healthy aorta. The paper presents an analysis of hemodynamic changes in the flow associated with the correction of pathology, both in the Newtonian formulation and considering the real properties of the blood (Carreau-Yasuda viscosity model). Based on the results, recommendations for the treatment of aortic coarctation using the balloon angioplasty method were adjusted.
