Fig. 1. — Conventional angiography of the vertebra-basilar system antero-posterior view. (A) Recanalized right PICA aneurysm with significant coil compaction. (B) PICA aneurysm at 8-weeks follow-up of the PED shield deployment. (C) Dragonfly OCT catheter safely advanced along distal access catheter to the basilar artery after 8-weeks of PED Shield deployment. Dashed circles in (C) correspond to the cross sections from the OCT acquisition from within the vertebra-basilar system. (D-H) PED Shield struts, device wall apposition, and neointima development in the basilar artery (D). No neointima was seen over the basilar perforator (white arrow) (E) or the vertebra-basilar junction (F). (G) PED Shield struts, device wall apposition, and neointima development (green arrow) in the vertebral artery. (H) No neointima was seen over the PICA origin (white arrow). PICA, posterior inferior cerebral artery; PED, Pipeline embolization device; OCT, optic coherence tomography.
