Abstract

Endovascular stents are used to effectively treat atherosclerosis during angioplasty. Nowadays, this surgery is performed on younger and younger patients, so the stent can be in the body for over 30 years. The stent cannot be removed from the patient, so the in vivo stability of the stent and the effects of the human organism on the stent can only be investigated on postmortem explanted stents. Therefore, this study deals with the non-destructive investigation of explanted coronary stents. Our goal was to determine the causes of visible damages and to measure the changes in the technical state.
