Our aim was to report our experience of a stent-assisted coiling technique with double stents in {\textquotedblleft}Y{\textquotedblright} and {\textquotedblleft}X{\textquotedblright} configurations, with emphasis on safety, feasibility, and efficacy. MATERIALS AND METHODS: Clinical and angiographic outcomes of patients for whom the strategic therapeutic option was the stent-assisted coiling technique in a Y or X configuration for neck scaffolding from June 2006 to June 2013 were retrospectively analyzed. RESULTS: One hundred five aneurysms in 97 patients were treated during 100 consecutive procedures. There were 54.2\% (57/105) MCA, 28.6\% (30/105) anterior communicating artery, 16.2\% (17/105) basilar tip, and 1.0\% (1/105) ICA termination aneurysms. A Y stent placement was used to treat 87 aneurysms in 85 procedures; an X stent placement was used to treat 7 aneurysms in 6 procedures, while 9 procedures failed for 11 aneurysms. There were 10.0\% (10/100) procedure-related permanent neurologic deficits and 1.0\% (1/100) death. The immediate angiographic controls showed a complete occlusion in 47.6\% (50/105) of the aneurysms and a partial (neck or sac remnant) occlusion in 52.4\% (55/105). To date, 81.0\% (85/105) of the aneurysms have been followed up (mean, 17 months) with angiography, disclosing a recanalization in 5.9\% (5/85) and an improvement in 42.4\% (36/85). At discharge and follow-up, the mRS score was 0 in 83.5\% (81/97) of patients, 1 in 4.1\% (4/97), 2 in 3.1\% (3/97), 3 in 4.1\% (4/97), 4 in 3.1\% (3/97), and 6 in 2.1\% (2/97). CONCLUSIONS: Y and X stent-assisted coiling of complex and wide-neck intracranial bifurcation aneurysms is an effective technique.
