UNASSIGNED: OBJECT Pessimism exists regarding flow diversion for posterior circulation @entity439 because of reports of perforator territory @entity1188 and delayed @entity397 . The authors report the results of @entity1 who underwent Pipeline Embolization Device (PED) flow diversion using novel strategies for treatment of fusiform posterior circulation @entity439 , and compare these results with those from previously reported series. METHODS The authors conducted a retrospective review of data from consecutive @entity1 with @entity439 treated with the PED. RESULTS This review resulted in the identification of 12 such @entity1 (mean [   SD] age 55.1    14.1 years). Eleven @entity1 had symptoms; 1 had a dissecting @entity439 identified on imaging for neck @entity158 . The average @entity439 size was 13.25    4.5 mm. None of the @entity439 were @entity397 or previously treated. The average clinical follow-up duration was 22.1    10.7 months and radiological follow-up was 14.5    11.1 months from the index PED treatment. One @entity1 suffered a perforator @entity64 and had a modified Rankin Scale (mRS) score of 4 at last follow-up. Another @entity1 had a retained stent pusher requiring retrieval via surgical cut-down but recovered to an mRS score of 0 at last follow-up. Eleven (91.7%) of 12 @entity1 recovered to an mRS score of 0 or 1. Two @entity1 had aneurysmal remnants at 7 and 10 months, respectively, after the index PED, which were retreated with PEDs. At last follow-up, all 12 @entity439 were occluded and PEDs were patent. The minimum follow-up duration was 12 months from the index PED treatment; no @entity1 experienced delayed @entity548 , @entity64 , or in-stent @entity850 . CONCLUSIONS Flow diversion with selective adjunctive techniques is evolving to become a safer treatment option for posterior circulation @entity439 . This is the longest clinical follow-up duration reported for a single-center experience of flow-diversion treatment of these @entity439 .

The safety of Pipeline flow diversion in fusiform vertebrobasilar XXXX : a consecutive case series with longer-term follow-up from a single US center.
