入选标准

  • Age 18 years or older.
  • Pre-stroke (24 hours prior to stroke onset) independent functional status in activities of daily living with modified Rankin Score 0-
  • Diagnosis of acute ischemic stroke with study enrollment time < 24 hours from onset of symptoms.
  • Disabling stroke defined as a baseline NIHSS >
  • Confirmed symptomatic, large vessel occlusion of the intracranial internal carotid artery (ICA), MCA-M1 or MCA-M
  • The following imaging criteria must also be met:
  • For subjects 0-6hrs onset:
  • MRI criterion: volume of diffusion restriction as assessed by automated core volume software ≤50 mL OR
  • CT criterion: ASPECTS 6 to 10 on baseline CT or CTA-source images or, computed tomography perfusion (CPT) core as assessed by automated core volume software ≤50 mL.
  • For subjects 6-24hrs onset:
  • ≤20mL ischemic core volume if age >80
  • ≤30mL ischemic core volume if age <80 and NIHSS 10-20
  • ≤50mL ischemic core volume if age <80 and NIHSS >20
  • Signed informed consent from patient or legal representative

排除标准

  • Computed tomography (CT) or Magnetic Resonance Imaging (MRI) evidence of recent/ fresh hemorrhage on presentation.
  • Clinical history, past imaging or clinical judgment suggests that the intracranial occlusion is chronic.
  • Rapidly improving neurological deficits based on the investigator's clinical judgement.
  • Pregnancy; if a woman is of child-bearing potential and urine or serum beta HCG test is positive.
  • Severe contrast allergy or absolute contraindication to iodinated contrast.
  • Difficult endovascular access, difficult aortic arch or severe neurovascular tortuosity that will result in an inability to deliver endovascular therapy.
  • Evidence of dissection in the carotid or target artery for treatment.
  • Presence of a carotid artery stenosis or occlusion requiring balloon angioplasty or stenting at time of the procedure.
  • Renal failure (on dialysis).
  • Severe, sustained hypertension resistant to treatment (SBP >185 mmHg or DBP >110 mmHg).
  • Use of warfarin anticoagulation with International Normalized Ratio (INR) > 3.0 at the time of the procedure or any known hemorrhagic or coagulation deficiency.
  • Use of a direct thrombin inhibitor within the last 48 hours; partial thromboplastin time (PTT) > 2.0 times the normal prior to procedure.
  • Cerebral vasculitis or evidence of active systemic infection.
  • Suspicion of aortic dissection, presumed septic embolus or suspicion of bacterial endocarditis.
  • Clinical symptoms suggestive of bilateral stroke or occlusions in multiple vascular territories (e.g., bilateral anterior circulation, or anterior/posterior circulation).
  • A severe or fatal comorbid illness that will prevent improvement or follow-up or that will render the procedure unlikely to benefit the patient.

结局指标

主要结局

Successful revascularization

时间窗: Peri-Procedural

Defined as proportion of subjects with mTICI 2b-3 flow post treatment with the DAISe Thrombectomy Device.
