AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for people treated for a brain aneurysm with a MicroVention implant device, or treated for an ischemic stroke with a MicroVention clot-removal device. Their data are collected in a registry.
- Sex
- All sexes can join.
- Disease stage
- Cohort 1: a ruptured or unruptured aneurysm in the brain. Cohort 2: a stroke treated with a mechanical thrombectomy device (a device that removes the clot).
- Earlier treatment
- The treating doctor chose the MicroVention device on their own, outside this study. Cohort 2: the device is the first treatment used.
Main reasons for not taking part
- People who are, or are expected to be, unreachable for follow-up
- People taking part in another study that changes how the site treats patients
- People already in this study for the same condition

Microvention Aneurysm & Stroke Real-life Data Collection
The MAESTRO registry is a post-market, single-arm, non-interventional, multicenter registry
Inclusion: Patient, or another authorized person as per country-specific regulations, is informed of the data collection and gives non-opposition or consent prior to the data collection in accordance with institutional and geographic requirements; For Cohort 1, patient is treated for a ruptured or unruptured intracranial aneurysm using a commercially available MicroVention implant device as the primary treatment device and the decision to use this device has been made by the treating physician outside the context of the MAESTRO study; For Cohort 2, patient is treated using a commercially available MicroVention mechanical thrombectomy device as the first-line treatment strategy and the decision to use this device has been made by the treating physician outside the context of the MAESTRO study; Note: For the purposes of this protocol, ancillary/accessory devices such as balloon catheters, carotid stent for extracranial stenosis and other access devices are not considered primary treatment devices. Further, devices used for rescue following attempt of a different primary treatment device are not considered initial primary treatment devices.
Exclusion: Patient is or is expected to be inaccessible for follow-up; Patient is participating or intends to participate in another study that changes the site practice; Patient is already participating in the MAESTRO study for the same pathology.
