Images in a 42-year-old man presenting with an acute SAH. A, Left vertebral artery angiogram reveals a dissecting aneurysm with an asymmetrically fusiform appearance at the segment-bearing left posterior inferior cerebellar artery. At 42 months after treatment with double overlapping stents, a left vertebral angiogram (B) and 3D reconstruction images (C) show complete obliteration of the dissecting aneurysm sac with preservation of the left PICA.

Images in a 49-year-old man presenting with an acute SAH. A, Right vertebral angiogram reveals irregular dilation of the right intracranial vertebral artery with a pearl-and-string appearance, involving the origin of the right PICA. B, Right vertebral angiography 4 days after double-overlapping stent insertion shows partial resolution of the pearl-and-string appearance but reveals enlarged fusiform dilation of the dissected segment. C, Six-month follow-up angiogram after third overlapping stent reveals complete obliteration of the fusiform dilation with a preserved PICA and smooth reconstruction of the dissected segment.

Images in a 24-year-old woman presenting with SAH. A, Left vertebral angiogram reveals an asymmetrical fusiform dilation with a bleb (white arrow) of the basilar artery. B, Left vertebral angiogram immediately after a balloon-expandable coronary stent insertion reveals near-complete obliteration of the dissecting aneurysm sac. C, Left vertebral angiogram performed because of rebleeding 3 days after the single-stent placement shows an irregular-shaped and enlarged pseudoaneurysm (black arrow) of the basilar artery.
