Purpose To report the results of a retrospective analysis prospectively collected data evaluating safety and efficacy double layer stent engineered for carotid artery occlusive disease. Methods Between January 2014 February 2017, 138 patients (25.4% women; median age 71 years) underwent Casper implantation stenosis. Eligibility criteria included stenosis >70% vessel diameter (or >50% with ulceration) in symptomatic or asymptomatic >80% at bifurcation proximal internal artery. For all procedures, distal embolic protection device was used. The primary endpoint rate 90 day major adverse neurological events, defined as minor stroke, death by independent assessment. Results Stent deployment completed successfully cases without documented technical failure. There were no events mortalities within days. One thromboembolic occlusion small branch anterior cerebral occurred during procedure resolved systemic recombinant tissue plasminogen activator administration. New ischemic lesions, clinically silent, seen 6.5% on post-procedure MRI. Conclusion demonstrated treatment stenosis, failures throughout follow-up period. Its structure seems to combine adequate plaque scaffolding high adaptability.
