MicroNet-covered Stent System for Stroke Prevention in All Comer Carotid Revascularization
Long-term Outcomes of MicroNet-covered Stent Routine Use for Stroke Prevention in Symptomatic and Increased-risk Asymptomatic Carotid Stenosis Patients Requiring Revascularization by Neurovascular Team Decision: PARADIGM-EXTEND
John Paul II Hospital, Krakow
550 participants
Sep 1, 2015
INTERVENTIONAL
Conditions
Summary
All-comer study of unselected patients suitable for carotid artery revascularization to evaluate the feasibility, efficacy and safety of first line endovascular revasculariztion using MicroNet covered stent (CGuard™) in the treatment of consecutive symptomatic and increased-stroke-risk asymptomatic carotid lesions that require revascularization by Neurovascular Team decision.
Eligibility

- Symptomatic patients (history of transient ischemic attack, ischaemic stroke or amaurosis fugax within 6 months from index procedure) with index artery stenosis ≥50% assessed in angiography with NASCET method or
- Asymptomatic patients with index artery stenosis ≥70-80% assessed in angiography with NASCET method
