What this trial studies

This clinical trial aims to compare the efficacy and safety of the WEB device against other endovascular techniques for treating acutely ruptured intracranial aneurysms. Patients over 18 years old with specific aneurysm characteristics will be randomly assigned to receive either treatment. The study will assess outcomes related to the management of subarachnoid hemorrhage caused by the aneurysm. The goal is to determine which treatment provides better results for patients.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with an acutely ruptured intracranial aneurysm requiring endovascular treatment.

Not a fit: Patients with aneurysms larger than 10mm or those not located in specified arterial regions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients with ruptured aneurysms.

How similar studies have performed: While there have been studies on endovascular treatments for aneurysms, this specific comparison of WEB versus other techniques is relatively novel.

Eligibility criteria

Show full inclusion / exclusion criteria
Main Inclusion Criteria:

* Patient is above 18 years of age at the time of consent
* Patient has an identified acutely ruptured intracranial aneurysm requiring endovascular treatment (for the purposes of this study an acutely ruptured IA patient is defined as a patient with computed tomography (CT), magnetic resonance imaging (MRI), or lumbar puncture (LP) evidence of subarachnoid hemorrhage attributed to the index aneurysm within the last 30 days)
* Aneurysm dome diameter must be ≤ 10mm and within the diameter (and parent vessel diameter, as appropriate) range treatable by commercially available WEB devices as well as at least one other alternative commercially available endovascular treatment device used per hospital standard practice
* Aneurysm is located on the anterior communicating artery complex segment (ACom), internal carotid artery terminus (ICAt), anterior cerebral artery (ACA), middle cerebral artery (MCA), basilar apex, posterior communicating artery (PCom) or pericallosal artery
* Patient must be neurologically stable with a Hunt \& Hess score of I to III
* Patient or patient's legally authorized representative (LAR) has provided written informed consent

Main Exclusion Criteria:

* Aneurysm to be treated is unsuitable for endovascular treatment with commercially available WEB devices and/or all other available endovascular treatment techniques used per standard site practice
* Patient presenting as target aneurysm a blister like or dissecting aneurysm
* Patient has more than one aneurysm requiring treatment within 30 days of completion of treatment of the target aneurysm
* Patient with multiple aneurysms in whom ruptured aneurysm cannot be identified
* Patient has pre-morbid mRS \> 2
