INTRODUCTION: Preliminary studies suggest that flow-diverting stents may be suitable for the treatment of @entity439 . The safety and efficacy of using flow-diverting stents for vertebral artery (VA) @entity439 is not well defined. OBJECTIVE: To examine the fate of covering the posterior @entity5487 (PICA) in @entity1 undergoing placement of a flow-diverting stent for VA @entity439 . METHODS: Consecutive @entity1 who underwent placement of a Pipeline Embolization Device (PED) for treatment of an @entity439 of the V4 segment of the VA between April 2012 and June 2015 at our institution were retrospectively evaluated. Angiograms were reviewed to determine the patency of the PICA when the vessel origin was covered by the PED. RESULTS: 11 @entity1 with @entity438 who underwent treatment with the PED were identified. In each case the device covered the origin of the PICA. Follow-up angiography in eight @entity1 demonstrated @entity715 of the @entity439 with patency of the PICA. CONCLUSIONS: Flow-diverting stents can be used for the treatment of @entity438 . When appropriately sized to the vessel wall and positioned in the VA, the device may cover the origin of the PICA without impairing flow through the branching artery.
