Waffle-cone technique using solitaire AB stent for endovascular treatment of complex and wide-necked bifurcation cerebral aneurysms.
BACKGROUND
To explore the safety and opportunity of the "waffle-cone" technique for the treatment of intracranial aneurysm.


METHODS
From November 2009 and May 2012, consecutive data were collected from 136 patients with aneurysms treated by the stent-assisted coiling procedure. Six of these patients were treated using the "waffle-cone" technique.


RESULTS
All the 6 patients were complex, wide-neck, bifurcation cerebral aneurysms. And the angles between the parent artery and distal vessels are acute. Two ruptured aneurysms located at the terminus of basilar artery, three ruptured aneurysms located at the anterior communicating artery, and one ruptured aneurysm located at trifurcation MCA. All the 6 patients were treated using the "waffle-cone" technique, 4 patients had Raymond classification Class I and 2 patients had Class II after the procedure. No complications occurred perioperative. There were no lesion-related strokes or deaths during the 6-month follow-up period.


CONCLUSIONS
The "waffle-cone" technique is a safe, simple and alternative for the complex, wide-necked bifurcation aneurysms with acute angles between the parent artery and distal vessels. Long-term following-up results are needed to evaluate the efficacy of this technique.
