A man in his sixties with an incidentally discovered fusiform aneurysm of the left supraclinoid carotid artery (patient no.2). A) Left carotid artery angiogram demonstrates the large fusiform aneurysm. B) Position of flow diverter and stasis of contrast inside the aneurysm. C) Angiogram at 24 months shows that the aneurysm is still open. A second flow diverter was telescopically placed inside the first one. D) CT angiogram 6 months later reveals that the aneurysm is still not occluded.
