Objective To show a novel application of the stent for the embolization of branch incorporated wide-neck cerebral aneurysms that are not amenable to usual neck remodeling technique.
Methods From March 2012 to October 2016, 11 patients with wide-neck aneurysms were treated with “modified Waffle-cone technique” at our institution. Solitaire AB Remodeling Device was used for this technique and we placing the distal end of the stent into the neck of the aneurysms for purpose of preservation of incorporated branch. The aneurysms were located at the middle cerebral artery bifurcation (n = 5), P-com (n = 3), anterior choroidal (n=1), ophthalmic (n=1) and the basilar-SCA (n = 1). Patient demographics, aneurysm morphology, procedures, clinical and angiographic outcomes and follow up results were reviewed.
Results Successful deployment of the stent with preservation of the targeted artery and complete or near complete occlusion was achieved in 10 of 11 patients. One patient with SCA aneurysm, we retrieved the devices and change the treatment plan because of preserving the branch was unsure. No procedure-related complication was occurred in all cases.
Conclusion The modified waffle-cone technique may enhance the possibilities of the coil embolization of these selected cases. However, its safety and technical feasibility should be further evaluated by larger case series and long-term follow-up.
