A 45 year old woman presented with double vision and subsequent angiographic imaging revealed bilateral aneurysms of the ICA of which one was located in the right paraophthalmic ICA measuring 4.2 mm.

Residual flow to the neck of the saccular aneurysm was noted on immediate post-treatment angiography. The 10 months follow-up imaging (C) revealed that the aneurysm underwent progressive occlusion as there was no residual flow visible while the aneurysm displayed satisfactory coil coverage.</p

A 64 year old woman presenting with vision impairment was found to have an aneurysm measuring 5 mm that was located in the supraclinoid ICA segment.

<p>Pre-treatment angiographic imaging (A and B) revealed a saccular wide-necked aneurysm which was accessible by SAC. A Neuroform stent was successfully navigated, deployed and subsequent coiling was performed. Immediate post-treatment results (C and D) demonstrated only partial occlusion of the aneurysm and flow beyond the aneurysm neck was present. At 6-months follow-up imaging (E) no residual flow into the aneurysm sac was detectable. These results were stable at 18-months follow-up imaging (F) and emphasize the potential of aneurysms to undergo progressive occlusion after treatment by stent-assisted coiling.</p
