PulseRider is an aneurysm neck reconstruction device that provides parent vessel protection for aneurysm coiling. The objective of this study was to report early postmarket results with the PulseRider device.<\/jats:p>\n <\/jats:sec>\n \n METHODS<\/jats:title>\n This study was a prospective registry of patients treated with PulseRider at 13 American neurointerventional centers following FDA approval of this device. Data collected included clinical presentation, aneurysm characteristics, treatment details, and perioperative events. Follow-up data included degree of aneurysm occlusion and delayed (> 30 days after the procedure) complications.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n \n A total of 54 aneurysms were treated, with the same number of PulseRider devices, across 13 centers. Fourteen cases were in off-label locations (7 anterior communicating artery, 6 middle cerebral artery, and 1 A\n 1<\/jats:sub>\n segment anterior cerebral artery aneurysms). The average dome\/neck ratio was 1.2. Technical success was achieved in 52 cases (96.2%). Major complications included the following: 3 procedure-related posterior cerebral artery strokes, a device-related intraoperative aneurysm rupture, and a delayed device thrombosis. Immediately postoperative Raymond-Roy occlusion classification (RROC) class 1 was achieved in 21 cases (40.3%), class 2 in 15 (28.8%), and class 3 in 16 cases (30.7%). Additional devices were used in 3 aneurysms. For those patients with 3- or 6-month angiographic follow-up (28 patients), 18 aneurysms (64.2%) were RROC class 1 and 8 (28.5%) were RROC class 2.\n <\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n PulseRider is being used in both on- and off-label cases following FDA approval. The clinical and radiographic outcomes are comparable in real-world experience to the outcomes observed in earlier studies. Further experience is needed with the device to determine its role in the neurointerventionalist\u2019s armamentarium, especially with regard to its off-label use.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2019.5.jns19313","type":"journal-article","created":{"date-parts":[[2019,12,13]],"date-time":"2019-12-13T20:43:47Z","timestamp":1576269827000},"page":"1756-1765","source":"Crossref","is-referenced-by-count":16,"title":["Early postmarket results with PulseRider for treatment of wide-necked intracranial aneurysms: a multicenter experience"],"prefix":"10.3171","volume":"133","author":[{"given":"Visish M.","family":"Srinivasan","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aditya","family":"Srivatsan","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandro M.","family":"Spiotta","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Medical University of South Carolina, Charleston, South Carolina;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin K.","family":"Hendricks","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, Phoenix, Arizona;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew F.","family":"Ducruet","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, Phoenix, Arizona;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felipe C.","family":"Albuquerque","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Barrow Neurological Institute, Phoenix, Arizona;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajit","family":"Puri","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Massachusetts, Worcester, Massachusetts;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew R.","family":"Amans","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of California at San Francisco, San Francisco, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven W.","family":"Hetts","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of California at San Francisco, San Francisco, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel L.","family":"Cooke","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of California at San Francisco, San Francisco, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher S.","family":"Ogilvy","sequence":"additional","affiliation":[{"name":"Neurosurgical Service, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajith J.","family":"Thomas","sequence":"additional","affiliation":[{"name":"Neurosurgical Service, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandro","family":"Enriquez-Marulanda","sequence":"additional","affiliation":[{"name":"Neurosurgical Service, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ansaar","family":"Rai","sequence":"additional","affiliation":[{"name":"Department of Radiology, West Virginia University Hospital, Morgantown, West Virginia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SoHyun","family":"Boo","sequence":"additional","affiliation":[{"name":"Department of Radiology, West Virginia University Hospital, Morgantown, West Virginia;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew P.","family":"Carlson","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of New Mexico School of Medicine, Albuquerque, New Mexico;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
