About this trial

Prospective, single-center, clinical registry of patients with acute stroke of carotid artery bifurcation origin undergoing endovascular treatment using the Micronet-covered CGUARD Stent to seal the culprit lesion under proximal cerebral protection (by transient flow reversal using balloon catheter such as the MoMa or FlowGate) with thrombus retrieval achieved through active aspiration ± stentriever use.

A study involving clinical and cerebrovascular imaging data evaluation in consecutive patients with acute stroke of carotid artery bifurcation origin, presenting in the time-window and/or cerebral tissue window allowing guideline-indicated reperfusion by interventional management.

A registry of consecutive patients with the study condition. An open-label study, without randomization - a single arm, single-center study in John Paul II Hospital in Krakow, Poland.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Consecutive patients with acute ischemic stroke with carotid artery bifurcation stenosis/occlusion as culprit lesion.

Clinical picture of acute ischemic stroke, stroke-in-evolution, or crescendo TIAs.

Patient eligible for endovascular stroke therapy according to AHA/ASA stroke management and accepted for emergent stroke intervention by the local NeuroVascular Team Committee according to local standard of practice.

Signed informed consent form to participate in the study (obtained at the point of first feasibility; note that live-saving procedure track may be executed for performing intervention according to local regulations and routine practice in the center)

Disqualifiers

Known stroke cause other than the carotid bifurcation lesion

Lack of effective endovascular route needed for intervention

Any known contraindications to stroke endovascular management

Trial population

All-comers clinical registry of consecutive patients with acute ischemic stroke culprit lesion at the carotid bifurcation, cleared for emergent interventional management by the NeuroVascular Team Committee according to stroke management guidelines.

Time perspective

Prospective

Treatments tested in this trial

  • Thrombectomy and Stenting under neuroprotection

    Device

    Endovascular management of the stroke culprit lesion using the Micronet-covered CGuard stent under neuroprotection. Transient flow achieved using a balloon guide catheter (e.g. MoMa or FlowGate) with additional active aspiration/s at key procedural steps. If indicated, targeted (extra- and/or intracranial) thrombus retrieval using either a thrombus aspiration device and/or a stentriever. Use of pharmaco-sedation versus general anesthesia is as indicated clinically and is according to the anesthesiologist and operator decision - according to routine practice in the center. Patient pre-procedural (including imaging and other diagnostic work-up), procedural, and post-procedural (including blood pressure tight control) management, including pharmacotherapy, are according to the AHA/ASA stroke management guidelines and the devices IFUs. Overall study patient management and intervention is according to routine clinical practice in the study center.
