Inclusion criteria

1. Patient with small or large intracranial aneurysm, ruptured or unruptured, intended to be selectively treated with the OPTIMA coil system. Patients with recanalized aneurysms previously treated with coils exclusively are also eligible. Balloon and stent assisted coiling are allowed at index procedure. 2. In case of multiple aneurysms, patient can be included when only 1 aneurysm is treated during the procedure and none of the other aneurysms are treated up to 30 days post-procedure 3. Patient older than 18 years 4. Patient who has been informed of the study and has signed an informed consent form where applicable according to local regulations.

Design outcomes

Primary

MeasureTime frameDescription
Morbi-mortality at 30 days30 daysRate of adverse events including thromboembolic events, the bleeding/rebleeding episodes, the rate of retreated aneurysm and the rate of mortality occurring during the procedure and up to 30 days.
Clinical outcomes (mRS) at 30 days30 daysClassification of the patient clinical and neurological outcomes based on modified Rankin Scale from 0 (no symptoms a all) to 6 (dead). Global outcomes of mRS 0-2 are considered good and those of mRS 3-6 (including mRS 6 - deceased) are considered to be poor.

Secondary

MeasureTime frameDescription
Morbi-mortality at 12 months12 monthsRate of adverse events including thromboembolic events, the bleeding/rebleeding episodes, the rate of retreated aneurysm and the rate of mortality occurring within 12 months after the procedure.
Clinical outcomes (mRS) at 12 months12 monthsClassification of the patient clinical and neurological outcomes based on modified Rankin Scale from 0 (no symptoms a all) to 6 (dead). Global outcomes of mRS 0-2 are considered good and those of mRS 3-6 (including mRS 6 - deceased) are considered to be poor.
Aneurysm occlusion rateUp to 24h and 12 monthsPost-procedure and 12-month follow-up efficacy based on the assessment of the aneurysm occlusion rate according to the 3-grade Montreal scale (complete occlusion/neck remnant/aneurysm remnant).
