A 48-year-old male presented with subarachnoid hemorrhage (Fig. 51.1a). He was clinically well preserved. DSA and 3D angiography revealed a dissecting aneurysm of right vertebral artery (Fig. 51.1b, c). Left vertebral artery was also dissected with almost complete occlusion (not shown). The case was planned for stent-assisted coiling.
