Stent-Assisted Coil Embolization of Posterior Circulation Aneurysms Using Solitaire Ab

Abstract

The initial technical and clinical results of Solitaire AB stent-assisted coiling of different types of wide-necked aneurysms in the posterior circulation are highly encouraging, and this technique may improve the endovascular treatment of these aneurysms.

A Comparison of Functional and Physical Properties of Self-Expanding Intracranial Stents [Neuroform3, Wingspan, Solitaire, Leo(+), Enterprise]

“…Such a wire facilitates recatheterization of a stent once deployed but also carries the risk of distal vessel injury. As observed by other sites, the thrombogenicity of the Solitaire stent is low and allows deployment with heparinization and ASA induced antiaggregation only, without the administration of clopidogrel [35] . This is a major advantage in the treatment of patients with recently ruptured aneurysms.…”

“…The stent is more stable than Neuroform3 and less thrombogenic than Leo( + ) in our clinical experience. Due to the large cell size, catheterization of the aneurysm sac after stent deployment is well controllable and may be easier than with the competitors [35] . In our opinion, the Solitaire stent is less prone to microcatheter-induced deformation or displacement, which may happen with Neuroform and Enterprise, respectively.…”

“…Solitaire is currently not indicated for atherosclerotic stenoses and the in-stent restenosis rate associated with its application in atherosclerotic disease is unknown. Reconstructing vessel bifurcations by crossing stent-in-stent deployment (Y-confi guration) is possible with the Solitaire [35] . Leo and Leo + are braided stents, which can be repositioned after partial deployment [36] .…”

Potential for the Use of the Solitaire Stent for Recanalization of Middle Cerebral Artery Occlusion without a Susceptibility Vessel Sign

“…[1][2][3] However, its ability to be completely and safely retrieved after full deployment allows it to be used as a device for mechanical thrombectomy in patients with acute thromboembolic stroke. Many reputable studies have shown that entrapping and extracting the thromboembolus by using the Solitaire stent is fast and effective in vascular recanalization, especially when treating large arterial occlusions, including MCA occlusion.…”

Y-Configuration Stent Placement (Crossing and Kissing) for Endovascular Treatment of Wide-Neck Cerebral Aneurysms Located at 4 Different Bifurcation Sites

“…[1][2][3][4][5][6] However, it remains a challenge to successfully treat some complex wide-neck bifurcation aneurysms by using a single-stent technique. Although kissing-balloon-assisted coiling has been attempted, 7,8 this technique is almost impossible for treating extremely wide-neck bifurcation aneurysms such as those reported in this article.…”
