Figure 3b. Ruptured left posterior communicating artery aneurysm in a 53-year-old woman treated with GDC placement during the acute phase. The initial anatomic result was total occlusion. (a) MIP reconstruction of MR angiogram (three-dimensional time-of-flight spoiled gradient-echo sequence, 26.0/2.4) obtained 3 months after treatment shows no remnant. (b) Lateral DSA image of the left internal carotid artery obtained 3 months after treatment shows a 2-mm remnant (arrow) in the aneurysmal neck.
