Article Synopsis
- The study aimed to compare the biomechanical properties of two types of balloon-expandable covered stents, VBX and iCover, focusing on their use as bridging stents in fenestrated aortic endoprostheses.
- Three biomechanical tests were conducted on 12 stents to assess their bending strength, pullout force, and shear-stress force by using a dynamometer and analyzing the data microscopically.
- Results showed that while VBX required more force to bend when crimped, it needed less force when expanded compared to iCover, with both types showing similar pullout force results but different shear-stress forces at various deformations.
Background: Endovascular treatment of aortic diseases with complex anatomy may require an additional upper extremity arterial access (like axillary access) for support during aortic navigation and allowing the use of larger sheaths for thoracoabdominal antegrade access. The objective of this study is to evaluate the safety of the open axillary approach as adjuvant access in complex thoracoabdominal aortic endovascular interventions.
Methods: A monocentric retrospective study was performed, including all patients with a complex aortic endovascular procedure (fEVAR, bEVAR, chEVAR or TEVAR), elective or urgent, with open surgical exposure of the axillary artery as adjuvant access, between 2012 and 2022.
Background: Autologous arteriovenous fistula is usually the vascular access of choice for hemodialysis in patients with chronic kidney disease. Autologous forearm loops with cephalic or basilic vein are an alternative in those cases with a suitable forearm vein but with an unsuitable radial artery; however they are rarely used and there is little reported evidence of their usefulness. Our objective is to report our results on the creation of autogenous forearm loops as vascular access for hemodialysis.

This study aimed to describe the outcomes of surgical treatment and long term follow up in a large cohort.
Methods: This prospective cohort study collected data from patients with a true inflow artery aneurysm after AVF creation that was surgically repaired between 2010 and 2022.
