Eligibility Criteria
Inclusion Criteria
- •Diagnosed with acute ischemic stroke.
- •Arterial occlusion in the anterior cerebral circulation that was confirmed by CTA or MRA.
- •Subject could be treated intraarterially within 8 hours after symptom onset.
- •Prestroke Modified Rankin Score ≤
- •National Institutes of Health Stroke Scale (NIHSS) ≥6 and ≤
- •Patients or their legally authorised representatives provided signed, informed consent.
Exclusion Criteria
- •NCCT ASPECT score \<6,or the infarct volume exceeded 1/3 of the middle cerebral artery blood supply area.
- •CT/MR Showed midline shift or cerebral hernia, and ventricle occupying effect. Intracranial hemorrhage. CTA/MRA shows carotid artery dissection, severe stenosis, or complete occlusion, which requiring carotid stent implantation during thrombectomy; Bilateral acute stroke or multiple intracranial large vessel occlusion.
- •Females who are pregnant or lactating.
- •Severe allergy to contrast agents, nickel-titanium metal or its alloys.
- •Drug-resistant hypertension (defined as sustained systolic blood pressure \>185mmHg or diastolic blood pressure \>110mmHg).
- •Hemorrhagic tendency (including but not limited to platelet \<100\*109/L, heparin treatment within 48 hours with APTT ≥35s, taking warfarin with an INR \> 1.7).
- •Surgery or biopsy of parenchymal organs within the last 1 month
- •Any active or recent bleeding (gastrointestinal, urinary, etc.) within the last 1 month
- •Undergoing hemodialysis or peritoneal dialysis; exist of severe renal insufficiency (serum creatinine \>220umol/L or 2.5mg/dl)
- •Previous intracranial hemorrhage, subarachnoid hemorrhage, brain tumor.
Outcomes
Primary Outcomes
Good Neurological Outcome
Time Frame: 90±7 Days post-treatment
Good clinical outcome is defined as an modified Rankin Scale (mRS) score of 0-2 at 90 days. mRS 0-2 indicates functional independence 0 - No symptoms.
Technical Success
Time Frame: Immediately post-treatment
Using Cerebrovascular Interventional Procedural Control System successfully complete the catheters in placement, thrombectomy stent release, and thrombectomy system recovery, without manual conversion.
Secondary Outcomes
- Radiation Exposure(Immediately post-treatment)
- Symptomatic Intracranial Hemorrhage(36 hours post-treatment)
- Successful Recanalization Rate(Immediately post-treatment)
- All-cause Mortality at 90 days(Through 90 days)
- Successful Revascularization(Immediately post-treatment)
- Time from Groin Puncture to Reperfusion(Immediately post-treatment)
- Device-related Serious Adverse Events (SAEs)(Through 90 days)
