Abstract:
One of the factors that contribute to the development of aortic aneurysms is hemodynamic factors. In this study, we analyzed the hemodynamic changes in a stented saccular abdominal aortic aneurysm model to improve hemodynamic factors. We discovered that stenting reduced wall shear stress, mean flow velocity in the aneurysm, energy loss, and pressure loss coefficient, and improved hemodynamics around the saccular abdominal aortic aneurysm. Stenting is expected to become a new treatment modality for abdominal aortic aneurysms. (This is a translation of J Jpn Coll Angiol 2022; 62: 111-119.).
