FIG 2. Patient 2.

A, Angiogram shows a small broad-based blisterlike aneurysm on the lateral wall of the distal ICA on the right. A balloon-expanded stent has been advanced to the level of the aneurysm orifice but has not been dilated. The tip of the guidewire is in the middle cerebral artery.

B, Angiogram obtained immediately after stent placement shows persistent but slower flow into the aneurysmal lumen.

C, Control angiogram obtained 3 months after intervention shows that the ICA is fully patent and the aneurysm totally thrombosed.
