Brief summary

The purpose of this post-market registry is to collect real-world data associated with the use of Medtronic market-released neurothrombectomy devices in acute ischemic stroke (AIS) patients from countries in South East Asia.

Detailed description

This is a prospective, multi-center, non-randomized, observational registry designed to collect real world data associated with the use of Medtronic market-released neurothrombectomy devices in acute ischemic stroke (AIS) patients from countries in South East Asia, including Singapore, Thailand and Vietnam. The primary objective of this registry is to assess clinical outcomes associated with the use of these devices in patients experiencing AIS due to large intracranial vessel occlusion within 8 hours of symptom onset. This registry may enroll up to 500 patients. This clinical trial information was submitted voluntarily under the applicable law and, therefore, certain submission deadlines may not apply. (That is, clinical trial information for this applicable clinical trial was submitted under section 402 (j)(4)(A) of the Public Health Service Act and 42 CFR 11.60 and is not subject to the deadlines established by sections 402 (j)(2) and (3) of the Public Health Service Act or 42 CFR 11.24 and 11.44.)

Inclusion criteria

1. Subject/subject's legally authorized representative has given Informed Consent according to country regulations, and/or EC requirements. 2. Subject has experienced an Acute Ischemic Stroke due to large intracranial vessel occlusion in at least one of the following intracranial vessels: internal carotid artery (ICA), M1 and M2 segments of the middle cerebral artery (MCA), basilar, and vertebral arteries. 3. Subject has been or will be treated with a Medtronic market-released neurothrombectomy device as the initial device used to remove the thrombus. 4. Subject is willing to participate in a 90-day follow-up visit. 5. Treatment within 8 hours of stroke symptom onset (defined as stroke onset to access puncture).

Exclusion criteria

1\. Concurrent participation in another mechanical neurothrombectomy device trial or any other clinical trial with an active treatment arm or where the study procedure or treatment might confound the study analysis.

Number of Participants With Symptomatic Intracranial Hemorrhage (sICH) at 24 Hrs ± 8 Hrs Post Procedure24 hrs ± 8 hrs post procedureNumber of participants with symptomatic Intracranial hemorrhage (sICH) is defined as \>/= 4 points worsening from baseline on the National Institutes of Health Stroke Scale (NIHSS) associated with an image finding of intra-cranial hemorrhage (i.e., intracerebral or intraventricular) at 24 +/- 8 hrs post procedure. The NIHSS is a 15-item neurologic examination stroke scale used to evaluate the effect of acute cerebral infarction on the levels of consciousness, language, neglect, visual-field loss, extraocular movement, motor strength, ataxia, dysarthria, and sensory loss. NIHSS scores range from 0 - 42. A score of 0 indicates no stroke symptoms. Higher scores indicate incremental levels of neurological impairment.
