Advances in Flow-diversion Devices for Cerebral Aneurysms

Flow diversion has become an increasingly used tool in the armory of the interventional neuroradiologist. Since the introduction of these devices approximately a decade ago there has been a major shift in their use. With greater experience clinicians have used them with ever greater frequency and are treating more complex cases. Similarly, these devices have now been used distal to the circle of Willis with good results. Although the technology is no longer new, significant advances are still made. Newer devices, such as the Silk Vista Baby, are able to be deployed through 0,17 inch microcatheters, and devices with surface coatings requiring single anti-platelet agents and fully visible DFT devices. These advances in technology are making the potential treatment of distal aneurysms and ruptured aneurysms more amenable to flow diversion, which has previously been shown to provide aneurysm occlusion similar to that of clipping.

Recently, there has been a significant number of advances within the arena of flow diversion, including the aforementioned new devices, as well as the new coatings that inhibit stent thrombosis. The goal of this Research Topic is to present the most recent advances on these topics so that readers would be up-to-date with all of the recent technological advancements made, as well as to provide patients and clinicians with the most up-to-date information on safety and efficacy.

For this Research Topic, Editors welcome manuscripts on, but not limited to, the following topics:
• New devices – Silk Vista Baby, p48, FRED Jnr. etc
• Surface Coating – p48and p64 HPC, Pipeline Shield
• Benchside testing – comparison between devices
• Use of software to optimize device sizing and selection
• Pre-operative flow modelling for the treatment of bifurcation aneurysms
