Stent-assisted coil embolization of intracranial aneurysms using Solitaire stent

Abstract

To report patients with intracranial wide-necked or complex aneurysms who underwent Solitaire stent-assisted coil embolization. Retrospective analysis of 28 patients with intracranial wide-necked or complex aneurysms. Eighteen of the patients presented with an acute subarachnoid hemorrhage. Thirty-one aneurysms were treated with the support of different applications (n = 32) of the Solitaire AB stents followed by the standard coiling procedure (n = 30). Successful positioning of the remodeling device was obtained in all the cases. One stent required repositioning after full deployment. There were four thromboembolic complications (12.5%) and two hemorrhagic complications (6.25%), which caused three deaths. No permanent procedural morbidity was observed in the surviving patient. Angiographic results included 26 complete occlusions (83.9%), three neck remnants (9.7%) and two incomplete occlusions (6.4%). Although the initial technical and clinical results of Solitaire stent-assisted coiling of aneurysms was reported to be encouraging in recent reports, we had encountered higher thromboembolic and hemorrhagic complications in our patients.
