Flow and wall shear stress characterization after endovascular aneurysm repair and endovascular aneurysm sealing in an infrarenal aneurysm model

Most endografts for endovascular aortic aneurysm repair involve a modular stent design, and the design could vary in the location of the flow divider. Endovascular aneurysm sealing based on polymer filling of endobags surrounding dual stent frames was recently introduced. This study focuses on effects of a dual-lumen configuration in the abdominal aorta after endovascular aneurysm sealing on flow and wall shear stress proximal and distal to the stents in comparison with two endovascular aneurysm repair endografts and an aneurysm control by in vitro flow visualization.
