The LVIS/LVIS Jr. stents in the treatment of wide-neck intracranial aneurysms: multicentre registry

Abstract

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.

Dual Stenting Using Low-Profile LEO Baby Stents for the Endovascular Management of Challenging Intracranial Aneurysms

“…14 This difference may have prevented incomplete stent opening in the 20 stents deployed in this series. This adverse event occurs at a rate of 6%-7% with the LVIS Jr. 24,25 One technical complication, stent migration into the aneurysm after deployment, developed in 1 of our patients, but this complication did not result in any clinical consequences. Stent migration during deployment was reported by using other types of open-cell or closed-cell stents, but migration may be more of a concern with low-profile braided stents because they have a lower radial force.…”

“…24,25 Finally, the LEO Baby stent fits inside microcatheters with luminal diameters of 0.0165 inches; therefore, these stents may exhibit improved navigation within arteries or through already-deployed stents. The struts of LEO Baby stents are not fixed (ie, the struts can move over each other); this feature makes room for the second stent and decreases the constraint on the second stent at the level of the stent intersection.…”

Stent-Assisted Coiling of Wide-Neck Intracranial Aneurysms Using Low-Profile LEO Baby Stents: Initial and Midterm Results

“…The immediate complete occlusion rate was 73%. Poncyljusz et al 18 reported an immediate complete occlusion rate of 85% by using either LVIS or LVIS Jr stents. The immediate total occlusion rate of 75% in our study is comparable with the results of previous studies.…”

Endovascular Coiling of Wide-Neck and Wide-Neck Bifurcation Aneurysms: A Systematic Review and Meta-Analysis

“…In fact, a recently published multicenter registry on the use of the LVIS stent (MicroVention, Tustin, California) in treating wide-neck aneurysms found complete and near-complete occlusion rates of 82% and 6%, respectively. 13 Flow diverters such as the Pipeline Embolization Device (Covidien, Irvine, California) and Silk Device (Balt Extrusion, Montmorency, France) are increasingly being used in the treatment of complex, wide-neck intracranial aneurysms, particularly aneurysms of the ICA. In the Pipeline for Uncoilable or Failed Aneurysms clinical trial including over 100 patients with large and giant wide-neck ICA aneurysms, the rate of complete angiographic occlusion at 12 months was 87%, with only 5.5% of patients having residual aneurysm.…”
