Article Figures & Data
Figures
- Fig 1.
Examples of 3 aneurysms treated with intrasaccular devices that are completely occluded at follow-up. Left column (A, C, and E) shows visualizations of the inflow jet before treatment, and right column (B, D, and F) shows corresponding visualizations immediately after treatment. Upper row, ICA bifurcation aneurysm. Center row, MCA bifurcation aneurysm. Lower row, Anterior communicating artery aneurysm.
- Fig 2.
Examples of 3 aneurysms treated with intrasaccular devices that are incompletely occluded at follow-up. Left column (A, C, and E) shows visualizations of the inflow jet before treatment, and right column (B, D, and F) shows corresponding visualizations immediately after treatment. All 3 aneurysms were at the MCA bifurcation.
