The authors report their initial experience with respect to the potential utility and long-term clinical outcomes of using a flow-diverting device in the treatment of unruptured dissecting VA aneurysms.<\/jats:p><\/jats:sec>\n\nMethods<\/jats:title>\nThe authors conducted a retrospective review of all cases of unruptured intracranial VA dissecting aneurysms treated at their institution (Tuen Mun Hospital) with a flow-diverting device. They describe the clinical presentations and angiographic features of the cases and report the clinical outcome (with modified Rankin Scale [mRS] scores) at most recent follow-up, as well as results of the latest angiographic assessment, with particular focus on in-stent patency and side-branch occlusion.<\/jats:p><\/jats:sec>\n\nResults<\/jats:title>\nA total of 4 aneurysms were successfully obliterated by using flow-diverting devices alone. Two devices were deployed in a telescoping fashion in each of 2 aneurysms, whereas only 1 device was inserted in each of the other 2 aneurysms. No periprocedural complication was encountered. No patient showed any angiographic evidence of recurrence, in-stent thrombosis, or side-branch occlusion in angiographic reassessment at a mean of 22 months after treatment (range 18\u201324 months). As of the most recent clinical follow-up (mean 30 months after treatment, range 24\u201337 months), all patients had favorable outcomes (mRS Score 0).<\/jats:p><\/jats:sec>\n\nConclusions<\/jats:title>\nReconstruction using a flow-diverting device is an attractive alternative in definitive treatment of dissecting VA aneurysms, demonstrating favorable long-term clinical and angiographic outcomes and the ability to maintain parent artery and side-branch patency. It is particularly useful in cases with eloquent side-branch or dominant VA involvement.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2011.12.jns111514","type":"journal-article","created":{"date-parts":[[2012,1,20]],"date-time":"2012-01-20T15:28:40Z","timestamp":1327073320000},"page":"882-887","source":"Crossref","is-referenced-by-count":71,"title":["Long-term outcome of endovascular reconstruction with the Pipeline embolization device in the management of unruptured dissecting aneurysms of the intracranial vertebral artery"],"prefix":"10.3171","volume":"116","author":[{"given":"Tsz Wai","family":"Yeung","sequence":"first","affiliation":[{"name":"Department of Radiology, Tuen Mun Hospital, Tuen Mun, New Territories;
