A and B, Post-treatment subtracted (A) and nonsubtracted (B) selective angiograms of the right ICA show complete occlusion of the aneurysm. A dense cast of the polymer fills the aneurysm. The parent artery is patent.
C and D, Time-of-flight (C) and phase-contrast (D) MRAs show complete occlusion of the giant aneurysm. The parent artery is patent but markedly narrowed (arrows) due to the presence of the stent, which results in a signal intensity loss.
