Closed-Cell Stent for Coil Embolization of Intracranial Aneurysms: Clinical and Angiographic Results

Abstract

BACKGROUND AND PURPOSE:Recanalization is observed in 20 -40% of endovascularly treated intracranial aneurysms. To further reduce the recanalization and expand endovascular treatment, we evaluated the safety and efficacy of closed-cell SACE. MATERIALS AND METHODS:Between 2007 and 2010, 147 consecutive patients (110 women; mean age, 54 years) presenting at 2 centers with 161 wide-neck ruptured and unruptured aneurysms were treated by using SACE. Inclusion criteria were wide-neck aneurysms (Ͼ4 mm or a dome/neck ratio Յ2). Clinical outcomes were assessed by the mRS score at baseline, discharge, and follow-up. Aneurysm occlusion was assessed on angiograms by using the RS immediately after SACE and at follow-up.

Surpass Flow Diverter in the Treatment of Intracranial Aneurysms: A Prospective Multicenter Study

“…If we restricted the analysis to unruptured or nonacutely ruptured aneurysms, the rates of morbidity and mortality varied between 3.8%-8.3% and 0%-3.9%, respectively. [28][29][30][31][32][33][34] The data presented in our study show a safety profile comparable with that of stentassisted coil embolization.…”

Stent-Assisted Coiling of Intracranial Aneurysms

“…Likewise, other groups have reported that SAC of ruptured aneurysms is associated with increased morbidity and mortality. 2,15,16 Thus, the safety-efficacy profile of SAC is clearly less favorable in ruptured than in unruptured aneurysms. In some patients with acutely ruptured aneurysms, however, SAC is the only available treatment option.…”

Hemodynamics of 8 Different Configurations of Stenting for Bifurcation Aneurysms

“…Several recent reports have demonstrated that SACE promotes occlusion of incompletely coiled aneurysms and lowers recanalization rates compared with nonstenting embolization, probably because of the hemodynamic effects of stents. [1][2][3][4][5] However, recanalization rates of SACE are 8.1%-17.2% 2,4,5 ; therefore, these rates still need to be improved. In addition, various configurations of stentings have been proposed and performed for bifurcation aneurysms, including a single stent from a proximal to a distal vessel; a waffle-cone stent 6 ; a horizontal stent [7][8][9] ; a nonoverlapping-Y stent 10 ; a kissing (double-barrel) Y stent, in which both stents are deployed in a parallel fashion 11,12 ; and a crossing-Y stent, in which the second stent is deployed through the interstices of the first stent.…”
