Fig. 2. — Selection of the WEB device (MicroVention, Aliso Viejo, CA, USA): ruptured anterior communicating artery aneurysm (informed consent for publication was not obtained so we anonymized the patient). (A) Non-contrast head CT showing bilateral subarachnoid hemorrhage. (B) 2D-DSA, front view, showing an anterior communicating artery aneurysm. (C) 2D-DSA, working view, showing the aneurysm. (D) 3D-DSA: measurements are performed to select the WEB device. Neck: 5.7 mm; width: 7.6 mm; height: 7.3 mm. (E) 3D-DSA, upper view of the dome. This view is very useful to measure the aneurysm width in 2 orthogonal directions: width 1: 9.0 mm; width 2: 7.0 mm. Mean width is 8 mm. (F) According to aneurysm measurements (D, E), A WEB SL 9x4 mm is selected. The device is oversized in width 1 mm and undersized in height 3 mm. (G) DSA, working view, after WEB detachment, showing complete aneurysm occlusion. (H) DSA, front view, after WEB detachment, showing complete aneurysm occlusion. (I) Flat-panel CT showing the WEB position in the aneurysm sac. (J) 1-year DSA showing complete aneurysm occlusion. WEB, Woven EndoBridge; CT, Computed Tomography; DSA, Digital Subtraction Angiography.
