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 model of a saccular abdominal aortic aneurysm 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.
A 57-year-old woman who had undergone an endovascular stenting from a right common iliac artery (CIA) to a right external iliac artery (EIA) for the occluded right CIA, was taking prednisolone internally with a systemic lupus erythematosus. She came to our hospital because of an intermittent claudication in her left leg. As a computed tomography revealed the right CIA aneurysm as well as an occlusion between a left CIA and EIA and a slightly dilated abdominal aorta, we electively performed the removal of stents and reconstruction of bilateral EIA with a bifurcated prosthetic graft.
