FIG 5. Case 3.

A, Anteroposterior and B, lateral DSA views demonstrate a broad-based, previously clipped, recurrent basilar tip aneurysm encroaching on the left P1 segment.

C, Angiogram reveals immediate stasis of contrast material in the aneurysm after stent deployment.

D, Angiogram reveals extravasation of contrast material after aneurysm perforation with the microcatheter (arrows).

E, Posteroanterior and F, lateral final angiograms after treatment show complete obliteration.

G, Angiogram shows that the right posterior cerebral artery is opacified via the internal carotid artery.
