Overview

Goal of the study is to evaluate the efficacy and safety of acute permanent stenting of symptomatic intracranial stenosis following unsuccessful recanalization by thrombectomy in acute ischemic stroke with large vessel occlusion using the self-expandable CREDO® heal Stent.

Eligibility

Inclusion Criteria:

• Patients, treated with CREDO® heal according to IFU and:
• With symptoms onset less than 24 hours before start of the procedure
• Treated with study device following at least one futile mechanical recanalization attempt with a stent retriever, direct aspiration or combination of both
• With pre-stroke disability mRS 0-2

Exclusion Criteria:

• Any contraindication according to IFU and patients:
• With atherosclerotic (probable according to clinical, anamnestic or laboratory chemical testing) vessel constrictions (high-grade intracranial stenoses > 70 %) with significant circulatory disturbance (haemodynamic infarct pattern and signs of restricted collaterals) and recurrent symptoms in spite of medical therapy
• With contraindication against treatment with anti-platelet medication
• With current effective use of oral anticoagulants (e.g. INR >1.7 for Vitamin K antagonists) or direct oral anticoagulants
• Participating in another trial
