ABSTRACT
Stent fracture is one of the major factors compromising implanted stent patency due to its consequences including in-stent restenosis, thrombosis, perforation, and migration. Stent fracture can occur from stress (extrinsic or intrinsic) and biomechanical forces at different implantation sites. We report on 2 cases of stent fractures and pertinent literature. One patient, a 75-year-old male, presented with recurrence of claudication 14 months after superficial femoral artery stenting; a femoral artery occlusion with stent fracture was found, and he underwent femoropopliteal bypass. The other patient, a 72-year-old male presented with recurrence of claudication; a stent fracture was found without femoral artery occlusion, and he was treated with additional femoral artery stenting to secure the fracture site.
