Early Supera stent fracture after treatment of popliteal artery occlusion caused by artificial knee joint: a case report.

ABSTRACT:

Background

The Supera stent, a self-expanding interwoven nitinol stent, has greater radial force than conventional stents, resulting in high patency and reduced stent fracture. There have been few reports of early stent fracture, and it is considered an effective device in the popliteal artery.

Case summary

We present a case of popliteal artery occlusion due to Supera stent fracture. An 86-year-old woman presented to our department with intermittent claudication after 6 months of Supera stent implantation. Ultrasonography demonstrated popliteal artery occlusion secondary to Supera stent fracture. Fluoroscopy revealed that the stent had fractured at the site closest to the artificial knee joint and might have been in contact with a vessel. In addition, the popliteal artery wa
