A 48-year-old man with intermittent dysphasia and dysarthria (patient 6). A and B, 3D and conventional frontal vertebral angiograms show a giant dolichoectatic fusiform aneurysm of the basilar artery. C, Two telescopically placed LEO stents are used as a scaffold for the flow diverter and coils. D, Lateral vertebral angiogram after a telescopically placed Silk flow diverter, coiling of the aneurysm lumen, and distal coil occlusion of the right vertebral artery (arrow). E, MR image before treatment shows a partially thrombosed aneurysm of the basilar artery with brain stem compression. F, MR imaging follow-up at 3 months demonstrates the thrombosed aneurysm with unchanged size.
