Trial characteristics_2

Developmental phase

Primary outcomes

1) Aneurysm cases
Reopening rate at 12 months of treatment
2) Arteriovenous malformation and arteriovenous fistula
Reoperation rate at 12 months of treatment

Key secondary outcomes

1) In addition to the evaluation of the following items at each time point, the transition and amount of change up to 12 months after treatment will be evaluated.
NIHSS, modified Rankin Scale (mRS), re-treatment or not, Raymond Scale (only for aneurysm cases), loss of venous perfusion (only for arteriovenous fistula cases)
2) Success rate of the procedure
3) Percentage of cases with >50% reduction in size (volume) of arteriovenous malformation immediately after treatment
