From: Neuroform EZ stenting for basilar artery atherosclerotic stenosis

Perforator occlusion occurred in one patient (3.0%) during the periprocedural period. (a–d) T2 and fluid attenuated inversion recovery sequence axial MRI displaying a small increase in signal intensity in the left side of the pons, indicated by the red arrow. Diffusion-weighted imaging sequences confirming the new infarction event. (e, f) MRA and high-resolution MRI indicating the patency of the basilar artery without in-stent restenosis.
