Figure 2a. Ruptured 4-mm anterior communicating aneurysm in a 64-year-old woman treated with endovascular GDC placement. Initially, this patient had total occlusion, but 3 months later, DSA depicted a small remnant in the aneurysmal neck. (a) Transverse source MR image and (b) MIP reconstruction of MR angiogram (three-dimensional time-of-flight spoiled gradient-echo sequence, 26.0/2.4) obtained 15 months after treatment show no remnant. (c) Lateral DSA view of the left internal carotid artery obtained 15 months after treatment shows a small remnant (arrow) at the base of the aneurysm.
