Study Arms (1)

Carotid Artery Stenting

Consecutive patients older than 18 yrs with symptomatic carotid artery stenosis qualified for endovascular revascularization.

Diagnostic Test: Intravascular Utrasound (IVUS) of Carotid Artery after implantation of CGuard stent

Interventions

Intravascular Utrasound (IVUS) of Carotid Artery after implantation of CGuard stent DIAGNOSTIC_TEST

IVUS will be performed after stent postdilatation to determine the incidence of plaque prolapse. Additionally optimizing stent expansion with IVUS is left at operator discretion.

• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Consecutive clinically-symptomatic patients (ipsilateral cerebral or retinal stroke or TIA with the preceding 6 months) with atherosclerotic de novo carotid artery stenosis causing at least 50% lumen reduction by quantitative carotid catheter angiography (QCA) or carotid stenosis of at least 50% lumen reduction by QCA in relation to documented ipsilateral ischaemic brain lesions/infarct on CT or MRI.

You may qualify if:

• All consecutive patients with clinically symptomatic carotid stenosis , or carotid stenosis associated with ipisilateral cerebral ischemic infarct/s on CT or MRI/DWI imaging, referred and accepted by the study center for CAS as per local standard referral pathways and study center routine.
• Patient informed consent to participate.
• Patient accepts follow-up scheme and consents to follow-up visits.

You may not qualify if:

• Lack of indication to carotid revascularization as per current ESC/ESVS Guidelines, or any clinical or angiographic or other contraindication to CAS (such as renal failure defined as creatinine level \> 2.5 mg/dL or eGFR \<20 ml/kg min, or incompatibility with DAPT).
• Surgery within the preceding 30 days or planned surgery within 30 days after CAS.
• Life expectancy \<1 year (eg. neoplastic disease).
• MI within 72h prior to CAS.
• Known coagulopathy.
• History of cerebral stroke with documented/known cause other than carotid disease.
• Atrial fibrillation or flutter.
• Any known cause for potential cerebral embolization different than carotid stenosis.
• History of intracranial bleeding.
• Any contraindications to as per IFU study device implantation.
