European Registry on the ACE Reperfusion Catheters and the Penumbra System in the Treatment of Acute Ischemic Stroke
European Registry on the ACE Reperfusion Catheters and the Penumbra System in the Treatment of Acute Ischemic Stroke
Prospective, single-arm, multicenter, observational registry of the ACE Reperfusion Catheters
 and the Penumbra System in Europe. Consecutive patients presenting within 6 hours from
 symptom onset with an acute ischemic stroke (within the internal carotid artery and internal
 carotid terminus, middle cerebral - M1/M2 segments) due to anterior circulation large vessel
 occlusion (LVO) will be treated using the ADAPT technique with thrombo-aspiration as first
 intention and site routine practice.
Prospective, single-arm, multicenter, observational registry of the ACE Reperfusion Catheters
 and the Penumbra System in Europe. Consecutive patients presenting within 6 hours from
 symptom onset with an acute ischemic stroke (within the internal carotid artery and internal
 carotid terminus, middle cerebral - M1/M2 segments) due to anterior circulation large vessel
 occlusion (LVO) will be treated using the ADAPT technique with thrombo-aspiration as first
 intention and site routine practice.

 The follow-up visit will occur 24 hours, 7-10 days or discharge, 30 days and 90 days
 post-procedure and will review patient's functional outcome, quality of life, and adverse
 events.
Inclusion Criteria:

 -  General inclusion criteria:

 -  From 18 years of age

 -  Present with symptoms consistent with an acute ischemic stroke within 6 hours of
 stroke symptom onset

 -  Arterial occlusion of the distal intracranial carotid artery (ICA and ICA
 terminus) or middle cerebral artery (M1/M2)

 -  National Institute of Health Stroke Scale (NIHSS) ≥ 2

 -  Signed Informed Consent Form.

 Imaging inclusion criteria:

 • CT ASPECT score from 6 to 10 (>6) or according to MR DWI ASPECT score from 5 to 10 (>5).

 Exclusion Criteria:

 -  General exclusion criteria:

 -  Associated myocardial infarction or severe infection (endocarditis or sepsis)

 -  Laboratory evidence of coagulation abnormalities, with an International
 Normalized Ratio (INR) of > 3.0 or platelets count < 40 x109/L or APTT > 50 sec

 -  Uncontrolled hypertension (defined as systolic blood pressure > 185 mmHg or
 diastolic blood pressure > 110 mmHg)

 -  Baseline glucose < 2.7 or > 22.2 mmol/L

 -  Pre-stroke mRS score > 2

 -  Seizure at the onset of stroke

 -  Arterial tortuosity that would prevent the device from reaching the target vessel

 -  Time of stroke symptoms onset unknown

 -  Life expectancy less than 90 days prior to stroke onset

 -  Females who are pregnant or lactating

 -  Known serious sensitivity to radiographic contrast media.

 Imaging exclusion criteria:

 -  CT/MRI evidence of the following conditions at screening:

 -  Significant mass effect with midline shift

 -  Evidence of intracranial hemorrhage (ICH), aneurysm, or arteriovenous
 malformation (AVM)

 -  Angiographic evidence of tandem extracranial occlusion or an arterial stenosis
 proximal to the occlusion that requires treatment prior to thrombus removal. Moderate
 stenosis not requiring treatment is not an exclusion criterion.

 -  Angiographic evidence of preexisting arterial injury, such as carotid dissection,
 complete cervical carotid occlusion, or vasculitis.
