Wide-necked bifurcation aneurysms often require the use of the technically complex Y-stent technique, which has recently been shown to narrow bifurcation angle in a hemodynamically favorable manner. We sought to evaluate the single center efficacy and safety of Y-stent supported aneurysm coil embolization. All patients undergoing Y-stent supported coiling between September 2006 and December 2012 were identified; records were analyzed for procedural results and complications, with follow-up evaluated for occlusion rate and neurological adverse events. Twenty consecutive patients underwent technically successful Y-stent supported coiling, with complete aneurysm occlusion achieved in 19/20 cases (95%). There were no peri-procedural clinically evident neurological complications following Y-stenting. Clinical follow-up was available for a mean of 20.0 months and radiographic follow-up was available for a mean of 18.5 months. During the follow-up period, three patients (15%) required re-treatment with through-stent coiling for recanalization. At latest follow-up, Raymond grade I occlusion was achieved in 16 patients (80%), Raymond grade II occlusion achieved in four patients (20%) and Raymond grade III occlusion in zero patients. Y-stenting for complex intracranial aneurysms appears effective in achieving durable aneurysm occlusion with an acceptable safety profile. Though the procedure is technically more complex than single-stent procedures, the Y-stent configuration should be considered when single-stent supported coiling is not feasible or sufficient.
