Presentation transcript:

Pretreatment 2D (A) and 3D (B) images show an irregular right MCA aneurysm with a bleb. Pretreatment 2D (A) and 3D (B) images show an irregular right MCA aneurysm with a bleb. Note that the aneurysm has no neck, and a branch is originating from the sac. Six-month control DSA image at a corresponding angle (C) reveals the sac decreased in size, but still filling (class 2). Correlative 1-year control DSA image demonstrates total occlusion of the aneurysm sac with the relevant branch filling retrogradely (white arrow) (ie, Cekirge-Saatci class 1c occlusion). C.
