Figure 4

Contrast-enhanced MR angiography maximum intensity projection images obtained 1 day (A, D), 3 months (B), and 12 months (C) after deployment of flow-diverting stent across from the right posterior communicating artery (Pcomm) to the right posterior cerebral artery (PCA)-P2 segment showing occlusion of a superiorly oriented P1 segment aneurysm at 3 months (orange solid arrow) and progressive occlusion of an inferiorly oriented P1 segment aneurysm (orange dotted arrow) at 12 month follow-up. Note the progressive increase in size of the right Pcomm and PCA-P2 junction (red arrows) and decrease in size of the right PCA-P1 segment (green arrows). Catheter angiogram obtained at 9 months (E, F) after stent deployment shows similar findings.
