Fig 2.

A, Intraprocedural frontal DSA image acquired during stent-assisted coiling of a right ICA dissecting fusiform aneurysm in a 61-year-old woman. Multiple DSA projections (not shown) were unable to define the coil mass position within the aneurysm and exclude material herniation into the A1 (arrow). B, Postprocedural conventional 64-detector MDCT source image with contrast offers no details of the devices or the adjacent vascular structures (0.95-mm source image). C, Contrast-enhanced CBCT (2.5-mm MIP) clearly shows the stent protecting the right A1 (arrow) and the coil mass secured within the aneurysm boundary.
