Values are n or mean (SD) with range.
Lesion length: mean:12.63 (5.82) mm, range 2.4–34 mm.
Protection device: Neuroshield (28), Percusurge (17), Angioguard (14), Epi (8).
*The three lesions not treated are not included.
†Stent: Wallstent (74), X.Act (9), SMART (7), Expander (2), AVE (2), Corithian (1), Palmaz (2), Megalink (1), Dynalink (1).
‡Three carotids could not be cannulated owing to inability to approach the target vessel.
LICA, left internal carotid artery; LSA, left subclavian artery.
