A, Oblique view, left vertebral artery injection showing a 4.0 × 2.5 × 2.0-mm basilar apex aneurysm. B, The patient underwent balloon-assisted coiling. There is a small (1.5-mm) residual at the base noted (arrow). C, Oblique view, left vertebral artery injection. The patient returned for balloon-assisted coiling of the aneurysm with near-complete occlusion of the aneurysm. An Enterprise stent was placed at the conclusion of the coiling to assist with flow redirection. (Arrows denote distal and proximal stent markers.) The P1 segment of the PCA measured 1.40 mm, the distal basilar artery at the level of the superior cerebellar arteries measured 2.33 mm, the distal basilar trunk measured 1.96 mm, and the proximal basilar trunk measured 2.55 mm.

A, Oblique view, left vertebral artery injection. The patient was brought back 3 months after initial treatment for additional treatment. She underwent another balloon-assisted coiling procedure with near-complete occlusion of the aneurysm and had an Enterprise stent placed from the left P1 segment of the PCA to the midbasilar artery trunk. (The distal and proximal tines of the stent are shown by the arrows.) B, Oblique view, left vertebral artery injection. Another angiogram performed 5 months after placement of the Enterprise stent shows clear migration of the stent from the left P1 PCA to the distal basilar artery. (The distal and proximal stent tines are shown by the arrows.) The aneurysm remains well occluded.
