With the advent of adjunctive devices such as balloons or stents, recanalisation rates have decreased secondary to better packing.Purpose The purpose of this registry was to evaluate the safety and effectiveness of the new Low-profiled Visualized Intraluminal Support LVIS and LVIS Jr. stents in the treatment of unruptured wide-neck intracranial aneurysms.Methods The LVIS or LVIS Jr. stent-assisted coil embolisation was performed in 78 patients harbouring 78 intracranial aneurysms. There were 59 aneurysms located in the anterior circulation and 19 in the posterior circulation. Clinical data and 6-month follow-up angiograms are presented.Results The LVIS and LVIS Jr. stents were successfully delivered to the target aneurysm; however, there were seven cases in which the LVIS/LVIS Jr. stents had suboptimal opening and apposition to the parent vessel wall. The overall technical success for all groups was 91% (71 of 78 stents). There was complete angiographic occlusion in 66 (85%) of 78 cases and residual neck remnants in 12 (15%) cases. All patients had 6-month angiographic follow-up, which demonstrated complete occlusion of the target aneurysm in 64 (82%) cases, residual neck remnants in 5 (6%) cases and there was aneurysm filling in 9 (12%) cases.Conclusions The LVIS/LVIS Jr. stent system is safe and effective for the treatment of wide-neck intracranial aneurysms, providing suitable support of the coil mass, which allows for a high level of occlusion with low rates of recanalisation and subsequent treatments.
