Figure 1From: Successful treatment of a ruptured aneurysm at the vertebral artery-posterior inferior cerebellar artery junction and simultaneous treatment of the stenotic vertebral artery with a single flow-diverting stent: a case report Preoperative computed tomography and angiographic findings in the posterior fossa. (a) CT angiography in a 68-year-old male showing the aneurysm with calcified neck imprinted in the brain stem. (b-c) Vertebral angiography with contrast injection in the left vertebral artery (AP projection) and rotational angiography with 3D reconstruction of the vertebro-basilar system show an irregularly shaped, saccular aneurysm localized at the left VA-PICA junction. (d) Right vertebral angiography shows distal occlusion of the V4 segment.Back to article page
