BACKGROUND: Double stenting in a Y configuration may be used to treat a @entity439 not amenable to reconstruction with a single stent. OBJECTIVE: We studied the feasibility, safety, and mid-term angiographic outcome of @entity1 treated using this technique. METHODS: A retrospective review was undertaken of all coil embolizations of wide-necked @entity439 using double stents in a Y configuration. RESULTS: Nineteen @entity1 were identified from 2002 to 2010 (14 @entity1 , 5 @entity1 ) with a mean age of 57.4 years. Stents were deployed in a Y configuration achieving complete occlusion (5/19), residual neck (5/19), and residual @entity439 filling (9/19). Angiographic follow-up was available for a mean of 16 months, and clinical follow up was available for a mean of 21.4 months. The incidence of complications at the initial treatment was 6 of 19 (31.6%), and delayed @entity1031 complications occurred in 2 of 19 (10.5%). An angiographic neck recurrence requiring retreatment developed in only 1 of the @entity1 in whom complete occlusion was obtained with the initial treatment. Spontaneous @entity715 and complete occlusion on follow-up imaging were found in 6 @entity1 in whom initial neck or @entity439 filling was observed. Ultimately, 12 of the @entity439 (63.2%) were completely occluded on follow-up angiography. CONCLUSION: Y-stent reconstruction enables the endovascular management of otherwise complex, wide-necked @entity438 and can be performed safely in experienced hands with satisfactory mid-term results, even in cases requiring retreatment.
