Abstract

Background: Nitinol interwoven bare metal stents represent an advancement in stent technology; however, nominal deployment remains an area of focus. Intravascular ultrasound (IVUS) has been shown to improve outcomes in both the coronary and peripheral vasculature by providing the operator with greater vessel detail; however, the use of adjunctive IVUS with nitinol bare metal stents has not been widely studied. This studies aims to determine the effect of IVUS when used adjunctively with nitinol interwoven bare metal stents in the management of femoropopliteal lesions. Design: Retrospective study. Methods: This study included a cohort of 200 consecutive patients with peripheral artery disease. All patients were treated with ≥1 Supera bare metal stent, and 91 received adjunctive IVUS imaging prior to stent deployment. Deployment conditions of nominal, compressed, and elongated were measured, and the primary clinical outcomes included target lesion reintervention, amputation, and mortality. This study also showed that 8.3 number needed to treat (NNT) patients must be treated with IVUS to avoid an additional revascularization event. Results: The patients who received IVUS had a significantly greater number of nominally deployed stents (p<0.001). Patients who had IVUS imaging also had significantly lower reintervention rates compared with those who did not receive IVUS imaging (p=0.047). Conclusion: The IVUS and angiography decreases clinically-driven target lesion reintervention and increases nominal deployment compared with angiography alone in femoropopliteal lesions treated with interwoven bare metal nitinol stents. Clinical Impact: Endovascular surgones may conisder the adjuctive use of IVUS when using the Supera stent for the treatment of infra inguinal superficial femoral artery lesions. The adjunct use of IVUS may lead to improved sizing, vessel prep, deployment, and ultiamtely reduction in CD-TLR.
