Given its high metal surface area coverage, there is concern for the patency of branch vessels that become covered by the device. Limited data exist regarding the patency of branch vessels adjacent to aneurysms that are covered by PEDs. The authors assessed the rate of intracranial internal carotid artery, anterior circulation branch vessel patency following PED placement at their institution.<\/jats:p><\/jats:sec>\n\nMETHODS<\/jats:title>\nThe authors retrospectively reviewed the records of 82 patients who underwent PED treatment between 2009 and 2014 and in whom the PED was identified to cover branch vessels. Patency of the anterior cerebral, posterior communicating, anterior choroidal, and ophthalmic arteries was evaluated using digital subtraction angiography preoperatively and postoperatively after PED deployment and at longer-term follow-up.<\/jats:p><\/jats:sec>\n\nRESULTS<\/jats:title>\nOf the 127 arterial branches covered by PEDs, there were no immediate postoperative occlusions. At angiographic follow-up (mean 10 months, range 3\u201334.7 months), arterial side branches were occluded in 13 (15.8%) of 82 aneurysm cases and included 2 anterior cerebral arteries, 8 ophthalmic arteries, and 3 posterior communicating arteries. No cases of anterior choroidal artery occlusion were observed. Patients with branch occlusion did not experience any neurological symptoms.<\/jats:p><\/jats:sec>\n\nCONCLUSIONS<\/jats:title>\nIn this large series, the longer-term rate of radiographic side branch arterial occlusion after coverage by a flow diverter was 15.8%. Terminal branch vessels, such as the anterior choroidal artery, remained patent in this series. The authors' series suggests that branch vessel occlusions are clinically silent and should not deter aneurysm treatment with flow diversion.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2016.4.jns16147","type":"journal-article","created":{"date-parts":[[2016,6,10]],"date-time":"2016-06-10T16:01:59Z","timestamp":1465574519000},"page":"1064-1069","source":"Crossref","is-referenced-by-count":99,"title":["Patency of anterior circulation branch vessels after Pipeline embolization: longer-term results from 82 aneurysm cases"],"prefix":"10.3171","volume":"126","author":[{"given":"Leonardo","family":"Rangel-Castilla","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Department of Neurosurgery, Gates Vascular Institute at Kaleida Health;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan A.","family":"Munich","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Department of Neurosurgery, Gates Vascular Institute at Kaleida Health;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naser","family":"Jaleel","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Department of Neurosurgery, Gates Vascular Institute at Kaleida Health;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marshall C.","family":"Cress","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Department of Neurosurgery, Gates Vascular Institute at Kaleida Health;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chandan","family":"Krishna","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Department of Neurosurgery, Gates Vascular Institute at Kaleida Health;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashish","family":"Sonig","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Department of Neurosurgery, Gates Vascular Institute at Kaleida Health;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth V.","family":"Snyder","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Radiology, and"},{"name":"Neurology, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, State University of New York;"},{"name":"Department of Neurosurgery, Gates Vascular Institute at Kaleida Health;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adnan H.","family":"Siddiqui","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Radiology, and"},{"name":"Department of Neurosurgery, Gates Vascular Institute at Kaleida Health;"},{"name":"Toshiba Stroke and Vascular Research Center, University at Buffalo, State University of New York; and"},{"name":"Jacobs Institute, Buffalo, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elad I.","family":"Levy","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Radiology, and"},{"name":"Department of Neurosurgery, Gates Vascular Institute at Kaleida Health;"},{"name":"Toshiba Stroke and Vascular Research Center, University at Buffalo, State University of New York; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns16147","series-title":"Int J Comput Fluid Dyn","doi-asserted-by":"publisher","first-page":"669","DOI":"10.1080\/10618560802495255","article-title":"Computational modelling of blood flow in side arterial branches after stenting of cerebral aneurysms","volume":"22","author":"Appanaboyina S,","year":"2008","unstructured":"Appanaboyina S, Mut F, Lohner R, Scrivano E, Miranda C, Lylyk P, : Computational modelling of blood flow in side arterial branches after stenting of cerebral aneurysms.
