Abstract

Introduction Dissecting and wide-necked aneurysms that incorporate a large portion of the parent artery can be challenging to treat with currently available devices. This study reports three cases treated with a new hybrid stent design that incorporates a smaller cell size and more pliable design than current generation stents and results in some flow diversion characteristics.

Methods In all three cases, use of the low-profile visible intraluminal support (LVIS) device in conjunction with coil embolization was determined to provide the best opportunity to achieve aneurysm occlusion while mitigating adverse events. The institutional review board reviewed all cases and approval was obtained. All cases were performed under emergent use exemption from the US Food and Drug Administration.

Results All three patients were successfully stent coiled with the LVIS device. One patient was completely occluded initially and remained so at follow-up, one patient progressed to complete occlusion at follow-up, and the last patient had stable incomplete occlusion of their fusiform aneurysm. There were no complications related to the procedures and the patients were maintained on dual-antiplatelet therapy.

Conclusion The LVIS device offers promise as a stent-assisted coil device with certain characteristics that may be advantageous over currently available microstents.
