FIG 3. 30-year-old man with subarachnoid hemorrhage at presentation in 1994.

A and B, Digital subtraction angiograms in anteroposterior (A) and lateral (B) projections demonstrate a fenestration and an associated aneurysm.

C, Follow-up angiogram in lateral projection after GDC treatment shows total occlusion.

D, Angiogram obtained 6 months later reveals recanalization due to coil compaction.

E and F, Follow-up angiogram immediately after treatment (E) shows total occlusion of the aneurysm, which turned out to be partially recanalized on the 1-year follow-up angiogram (F).
