† A complications was defined as an adverse event that was clearly a result of the procedure and that led to prolonged hospitalization or a change in the Rankin scale score of 1 or more points at discharge.
‡ This P value was determined with the Pearson χ2 test. All other P values were determined by using Wilcoxon rank-sum tests.
§ Additional coil embolization was needed for the treatment of an aneurysm during follow-up.
