In-vivo corrosion of endovascular stents presents two main risks; release of metallic debris and deterioration of the mechanical properties of the stents which may lead to fracture. Retrieval analysis of explanted nickel-titanium (NiTi) aortic stent grafts showed pitting corrosion and fracture of the NiTi wire component [1, 2].
