REscue Stenting With CREDO® Heal for Recanalisation After Unsuccessful Thrombectomy (RECHRUT)

• Patients, treated with CREDO® heal according to IFU
• Over 18 years old
• With acute persistent vascular occlusion due to high grade intracranial artery stenosis in the anterior or posterior circulation for which alternative therapy concepts are not considered or fail
• With suspected underlying stenosis of the occluded artery, which is suitable for PTA and stenting according to the treating physician's assessment and/or persistent occlusion after failed recanalization by mechanical thrombectomy of the target region
• With small to moderate infarct core prior to initiation of thrombectomy (CT ASPECTS 6-10, DWI lesion \< 70 ml)
• 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
• Participating in another trial
