BACKGROUND AND OBJECTIVE: Coiling of wide-necked basilar tip @entity439 is technically challenging and is often assisted by the placement of a stent. Stent placement in an anterograde fashion either with a single or Y-stent is typical. However, in some cases the @entity1416 ( @entity1416 ) angle of origin at the base of the @entity439 precludes anterograde catheterization. A series of @entity1 with wide-necked basilar tip @entity439 treated with a single stent placed via the posterior communicating artery from @entity1416 to @entity1416 is presented. METHODS: A retrospective database review was performed to identify all stent-coiled basilar tip @entity439 . @entity1 with attempted horizontal P1-P1 stenting via the posterior communicating artery were identified. Procedural imaging, follow-up angiography and clinical notes were reviewed. RESULTS: P1-P1 stenting was attempted in 10 @entity1 and was successful in eight. Angiographic follow-up was available in six @entity1 , all of whom had >90% obliteration at last follow-up. There was one procedure-related @entity510 that resulted in @entity1 @entity204 . There were no cases of significant @entity1416 on angiographic follow-up. CONCLUSIONS: This stenting technique is an effective way to treat wide-necked basilar tip @entity439 but is limited by the anatomy of the posterior communicating arteries and P1 segments.
