Wingspan Stent System
Self-expandable stents have broadened the spectrum of endovascular treatment of intracranial aneurysms. However, procedures involving double stenting in Y/X configurations carry a relatively high risk of procedural complications.
The Neuroform ATLAS, the evolution of Neuroform EZ, is a nitinol self-expanding hybrid/open cell stent which can be delivered through a low profile 0.017-inch catheter. Ciccio et al. presented the experience in the treatment of intracranial aneurysms with this stent in Y and X configurations.
They prospectively maintained a database from consecutive patients who underwent double stent-assisted coiling with the Neuroform ATLAS, from July 2015 to February 2019. Clinical and angiographic results were analyzed.
55 patients harboring 55 bifurcation aneurysms were treated with double stenting: 52 ‘Y’ configurations, 3 ‘X’ configurations. Deployment was successful in all cases. Post-treatment control angiography showed complete occlusion in 33 cases (60%), neck remnant in 8 cases (14.5%), and incomplete occlusion in 14 cases (25.4%). The overall symptomatic periprocedural complication rate was 12.7%. 38 aneurysms underwent follow-up (69%, mean duration 16 months): 33 aneurysms (87%) were completely occluded, 3 aneurysms (8%) had a neck remnant, and 2 aneurysms (5%) were incompletely occluded.
The Neuroform ATLAS is an effective device for the treatment of bifurcation aneurysms, allowing good conformability, a high level of navigability, and easy mesh crossing to perform Y/X stenting procedures. The rate of procedural complications remains non-negligible, and an indication for a double stenting procedure should be carefully discussed in a multidisciplinary meeting 1).
Neuroform EZ® Stent System
Flexible Design – Enhanced Delivery Introducing the industry leading self-expandable and conformable stent design with a simplified delivery system. By reducing stent delivery to three steps – Access, Advance, Deploy – enhanced control meets efficiency.
The Neuroform stent seems to be safe and technically effective in the endovascular management of distal cervical and intracranial dissections, with favorable clinical outcomes 2).
