About this study

Rationale: Intrasaccular neck occlusion devices have been used for unruptured aneurysm without safety concerns and good occlusion rates. In the setting of a subarachnoid hemorrhage, they could improve the rate of complete occlusion without safety concerns.

Aim: To explore the safety and efficacy of intrasaccular neck occlusion devices in patients with acute subarachnoid hemorrhage caused by a ruptured saccular aneurysm by a one arm prospective registry.

Study outcome: The primary outcomes is the rate of complete occlusion (Raymond-Roy I) and rebleeding at one year follow-up. The primary safety outcome is rate of rebleeding during the admission.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Neqstent or ContourDevice

    All patients included will be treated the same: after catheterizing the affected vessel and microcatheterizing the aneurysm with a microcatheter of 0.021'' or 0.027'', the intrasaccular device (Neqstent® or Contour®) will be positioned. Depending of the operator preference, the use of an intrasaccular device could be associated with coiling (mandatory in the case of Neqstent®). Treatment must be performed without previous double antiplatelet treatment (allowing antiplatelet after aneurysm exclusion). Before the treatment all patients should undergo a flat panel CT.

How can a doctor refer a patient or contact the research team?

Contact Alejandro Tomasello, MD (934893000 ext. 6748, alejandrotomasello@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Efficacy achieving the lack of rebleeding (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05171465, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
