説明
Inclusion Criteria:
- Patient age 18 - 80 years
- Treatment within 8 hours of symptom onset
- Pre-stroke mRS 0-2
- Patient experiencing acute ischemic stroke secondary to intracranial large vessel occlusion in the internal carotid, middle cerebral (M1 or M2), basilar, or vertebral artery
- If patient is eligible for thrombolytic therapy, it was administered as soon as possible, and no later than 3 hours from stroke symptom onset
- Planned frontline treatment with Penumbra System including Thunderbolt modulated aspiration
- Informed consent obtained per Institution Review Board/Ethics Committee requirements
Exclusion Criteria:
- Stenosis, excessive tortuosity, or any occlusion in a proximal vessel requiring treatment or preventing access to the thrombus
- Alberta Stroke Program Early CT Score (ASPECTS) ≤6 or core infarct volume >50 mL on MRI or CT-based imaging (for anterior circulation strokes)
- Pregnant patient
- Life expectancy < 90 days due to comorbidities
- Current participation in an interventional drug or device study that may confound the results of this study. Studies requiring extended follow-up for products that were investigational but have since become commercially available are not considered investigational studies
- Other medical, behavioral, or psychological conditions that in the opinion of the Investigator could limit the patient's ability to participate in the study, including compliance with follow-up requirements, or that could impact the scientific integrity of the study
