Figure 4d. Ruptured anterior communicating artery aneurysm in a 54-year-old man treated with endovascular GDC placement during the acute phase. This treatment resulted in subtotal occlusion. (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 3 months after treatment show no remnant. (c) Lateral and (d) oblique DSA views of the right internal carotid artery obtained 3 months after treatment show residual flow (arrows) in the coil mesh close to the neck.
