    Retreatment success§ 13/13 (100) 2/2 (100) 7/7 (100) 2/2 (100) 2/2 (100)

Note:—ICA indicates internal carotid artery; MCA, middle cerebral artery.

*

Vertebrobasilar junction is included with vertebral artery; anterior cerebral artery and posterior cerebral artery data are included in the overall column, but not in the breakdown by lesion location. The posterior cerebral artery case resulted in a periprocedural death and the anterior cerebral artery case resulted in a periprocedural complication (wire perforation).

Reduction of stenosis by at least 20% and lack of periprocedural complications.

The death was in the PCA case and is not included in the breakdown by location.
