The study investigated the effects of endovascular repair on local energy loss in patients with fusiform abdominal aortic aneurysm (AAA). 4D flow MRI was used to compare pre- and postoperative local energy loss and other hemodynamic parameters. Results showed an increase in local energy loss in postoperative patients, indicating that the repair procedure may have a negative impact on hemodynamics. The findings suggest that 4D flow MRI may be a valuable tool in assessing the effects of endovascular repair on AAA
