Abstract：Objective To investigate the clinical characters of intracranial wide-neck bifurcation aneurysms and evaluate the safety and clinical outcomes of treatment with Y-stent-assisted coils. Methods The clinical data of 16 patients with intracranial wide-neck bifurcation aneurysms treated by Y-stent-assisted coils from October, 2012 to October, 2015 was analyzed retrospectively. Results Of 16 consecutive patients undergoing successful Y-stent assisted coiling, 9 were treated by kissing Y-stent technique and 7 by crossing Y-stent technique. The aneurysms were completely occluded in all the patients (100%). One patent with Hunt-Hess grade 4 died from severe cerebral vasospasm 2 days after the operation. The mild neurological deficit occurred after the operation in 1 patient, in whom the occlusion of one main branch of bifurcation was observed by DSA 6 months after the operation. DSA showed that a large basilar apex bifurcation aneurysm recanalized 6 months after the operation. No rebleeding and recanalization of the aneurysms occurred in 13 patients who were followed up by DSA or CTA from 1 month to 3 years. Conclusions Y-stent-assisted coiling is an effective method to treat the complex intracranial wide-neck bifurcation aneurysms when single stent-assisted coiling is not feasible and sufficient. The long-term effect of Y-stent-assisted coiling on the wide-neck bifurcation aneurysms still should be further observed.
