Unruptured aneurysm of the basilar artery at the ostium of the left superior cerebellar artery (A). In a first session, the aneurysm was treated with the remodeling, resulting in complete occlusion (B). A growing aneurysm recurrence (C) was treated 13 months after the initial intervention by placing a WEB SL device (D). A late phase control run depicted a slowed down intra-aneurysmal blood circulation (E). Six-month DSA follow-up shows a neck remnant (F).
