Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in the rate of complete occlusion	Rate of complete aneurysm occlusion is assessed immediately after treatment (an expected average of 1 hour) and at both follow-up visits (3-6 months and 7-12 months). The change is assesed.	immediately after treatment, an expected average of 1 hour; to 12 months
Primary	Change of frequency of major stroke (ischemic or hemorrhagic) or neurological death related to the treatment of the target aneurysm	Frequency of major stroke (ischemic or hemorrhagic) or neurological death is assessed immediately after treatment (an expected average of 1 hour) and at both follow-up visits (3-6 months and 7-12 months). The change is assesed.	immediately after treatment, an expected average of 1 hour; to 12 months
Secondary	Intra-procedural technical complications	p64 placed in the desired location Correct opening of p64 (markers fully deployed) at the end of the procedure Ability to detach p64 at the end of the procedure	during treatment, an expected average of 1 hour
Secondary	Change of Angiographic results	Change in both Rate of re-growth (related rate of re-treatment) and Rate of recanalization (related rate of re-treatment) are assessed immediately after treatment (an expected average of 1 hour) and at both follow-up visits (3-6 months and 7-12 months).	immediately after treatment, an expected average of 1 hour; to 12 months
Secondary	Intra-procedural vascular complications	Vessel perforation (e.g. with distal wire tip of p64, microcatheter) Target aneurysm perforation (e.g. with distal wire tip of p64, microcatheter) Thromboembolism Dissection of any access vessel Side branch occlusion	during treatment, an expected average of 1 hour
Secondary	Post-procedural Complications	Parenchymal hemorrhage detected during the follow-up period Subarachnoid hemorrhage detected during the follow-up period Ischemic stroke detected on follow-up imaging Rupture of the target aneurysm detected during the follow-up period Rate of in-stent-stenosis detected during the follow-up period	3-6 and 7-12 months
