Endovascular treatment of femoro-popliteal artery stenosis/obstruction using a repositionable self-expanding nitinol stent: a preliminary study

Abstract

Introduction. The aim of this study was to report our preliminary results regarding the use of the repositionable self-expanding nitinol stent in a cohort of patients with femoro-popliteal artery occlusion/stenosis.

Material and methods. The study groups consisted a total of 8 patients (10 extremities) between 47 and 70 years of age who presented with typical symptoms of intermittent claudication and/or critical limb ischaemia (Fontaine stage II–IV) and underwent primary elective superficial femoral artery percutaneous transluminal angioplasty and/or stenting using a Jaguar repositionable self-expanding nitinol stent in the dates of 2013–2015. Information for patency at 6th month after the stenting procedure was obtained.

Results. The mean operation time was 38.56 ± 26.40 minutes. No patients had procedure-related stent fracture, distal thromboembolism, haematoma, femoral pseudoaneurysm or stent occlusion. At 6-month follow-up, at least one categorical improvement was observed in 7 patients (87.5% of intent-to-treat population).

Conclusions. The Jaguar self-expanding nitinol stent has several technical advantages, and its use was associated with a low risk of complications. Further study is warranted to establish its superiority in providing good long-term patency.
