Is this trial a fit for you?

Likely a good fit

Adults (≥18) with CT-confirmed aneurysmal subarachnoid hemorrhage, an angiographically identified aneurysm, WFNS grade 3–5, and consent via a legally authorized representative within 72 hours are the ideal candidates.

Probably not a fit

Patients whose aneurysm bleeds from the neck, those judged appropriate for balloon-assisted coiling, those expected to die within 24 hours, or pregnant patients are unlikely to benefit from this approach.

What this trial studies

This prospective observational study will collect data on adults with CT-confirmed aneurysmal subarachnoid hemorrhage treated with the guideline-recommended dome-protection coiling approach at a single center. Eligible patients are those with an angiographically confirmed aneurysm and WFNS grade 3–5 who provide consent via a legally authorized representative within 72 hours of hemorrhage. The primary outcome is the incidence of aneurysm re-rupture within 90 days, censored at definitive aneurysm treatment or death and detected on surveillance head CT or after neurologic decline. Secondary outcomes include 90-day functional status and angiographic measures of dome protection success and procedural complications, and the protocol is observational without randomization.

Why it matters

Potential benefit: If successful, dome protection could reduce early re-bleeding and lower immediate procedure-related risks, allowing safer stabilization before definitive aneurysm repair.

How similar studies have gone: Small case series and retrospective reports have suggested dome-protection or partial/coiling approaches can reduce early rebleeding, but prospective multicenter evidence is limited.
