From: A case of multiple Vertebrobasilar artery fenestration misdiagnosed as vertebral artery dissection
Multiple vascular abnormalities from the vertebrobasilar system in DSA. Extracranial DSA showing the vertebral artery fenestration at the V1 segment in the multiply direction (black arrows) (a-b). Intracranial DSA showing an ipsilateral large vertebral artery fenestration at the level of C1 and C2 (double white arrows), post-coil-embolization changes of giant aneurysm at the tip of basilar artery (small white arrow), and a small fenestration at the proximal basilar artery (long white arrow) (c-d).
