Distal intrinsic vasculopathy was much less common (n=13).Conclusions: Concurrent small-vessel vasculopathy was frequent in ICAD, and the predominance of orifical obstructive atheroma accounted for common occurrence of lacunar syndrome in ICAD and the risk of perforator jailing or occlusion during stenting in this subgroup.Disclosure: Dr. Leung has nothing to disclose.
