Background and purpose: Angioplasty and endovascular stent placement is used in case to rescue the coverage of main branches to supply blood to brain from aortic arch in thoracic endovascular aortic repair. This study assessed mechanical properties, especially differences in radial force, of different endovascular and thoracic stents. Material and methods: We analyzed the radial force of three stent models (Epic™, E-Luminexx® and SMART®) stents using radial force-tester method in single or overlapping conditions. We also analyzed radial force in three thoracic stents using Mylar® film testing method: conformable Gore®-TAG®, Relay®, and Valiant® Thoracic Stent Graft. Results: Overlapping SMART stents had greater radial force than overlapping Epic or Luminexx stents (P 0.01). The radial force of the thoracic stents was greater than that of all three endovascular stents (P 0.01). Conclusions: Differences in radial force depend on types of stents, site of deployment, and layer characteristics. In clinical settings, an understanding of the mechanical characteristics, including radial force, is important in choosing a stent for each patient.
