Patient with a left internal carotid cavernous aneurysm presenting with compression of cranial nerves (III and IV). MAFA ratio = 0.916. The natural evolution was predicted by the parameter. A, 3DRA of the left carotid artery. B, DSA, left ICA injection, lateral view. Pretreatment imaging. C, Nonsubtracted radiographic image. Lateral view. FDS implanted at the level of the left ICA covering the aneurysm neck region. D and E, DSA, left ICA injection, lateral view. Posttreatment imaging. Observe the contrast stagnation inside the aneurysm after the FDS placement. F, MR image. Postgadolinium 3D T1 image obtained at 12 months showing complete aneurysm resolution, vascular remodeling, and decompression of the cavernous sinus.
