Table 2:

Procedure outcomes by lesion location^*

	Procedures
	Overall (n = 84)	Basilar (n = 12)	Vertebral (Non ostial) (n = 28)	ICA (n = 32)	MCA (n = 10)
Outcome
Treatment success (%)†	76 (90.5)	12 (100)	25 (89.3)	30 (93.8)	9 (90.0)
Periprocedural complications during initial treatment (not including death) (%)	7 (8.3)	0 (0)	3 (10.7)	2 (6.3)	1 (10.0)
Periprocedural deaths (%))‡	1 (1.2)	0 (0)	0 (0)	0 (0)	0 (0)
Residual >50% (%)	11 (13.1)	1 (8.3)	6 (21.4)	3 (9.4)	1 (10.0)
Time to restenosis, mo mean (range)	4.59 (1–16)	6.25 (1–16)	4.50 (1.5–16)	2.88 (2–4)	3.5 (3–4)
Restenosis (%)	23 (27.4)	6 (50.0)	11 (39.3)	4 (12.5)	2 (20.0)
Restenosis with symptoms (%)	5 (6.0)	2 (16.7)	2 (7.1)	1 (3.1)	0 (0)
Retreatment for restenosis (with or without symptoms)	13 (15.5)	2 (16.7)	7 (25.0)	2 (6.3)	2 (20.0)
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.

^§Based on the 13 repeat procedures.
