Cranial dural arteriovenous fistula embolization was the most common indication (54.5%) followed by cranial arteriovenous malformation (27.3%). Staged\/pre-operative embolization was done in 36.4% of cases; and 83.6% of procedures using Onyx-18. Most procedures utilized a transarterial approach (89.1%), and SMB-induced arterial-flow arrest concurrently with transvenous embolization was used in 10.9% of procedures. Femoral access\/triaxial setups were utilized in the majority of procedures (65.5% and 60%, respectively). The median vessel diameter where the balloon was inflated of 1.8\u2005mm, with a median of 1.5 cc of injected embolic material per procedure. Technical failures occurred in 5.5% of cases requiring aborting\/replacement with other devices without clinical sequelae in any of the patients, with SMB-related procedural complications of 3.6% without clinical sequelae. Radiographic imaging follow-up was available in 76.9% of the patients (median follow-up 3.8 months), with complete occlusion (100%) or &gt;50% occlusion in 92.5% of the cases, and unplanned retreatments in 1.8%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The SMB microcatheter is a useful new adjunctive device for balloon-assisted embolization of cerebrospinal lesions with a high technical success rate, favorable outcomes, and a reasonable safety profile.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15910199241246135","type":"journal-article","created":{"date-parts":[[2024,4,13]],"date-time":"2024-04-13T05:27:07Z","timestamp":1712986027000},"page":"1379-1387","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Multicenter US clinical experience with the Scepter Mini balloon catheter"],"prefix":"10.1177","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2082-6892","authenticated-orcid":false,"given":"Mohamed M.","family":"Salem","sequence":"first","affiliation":[{"name":"Department of Neurosurgery"},{"name":"Hospital of the University of Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paz","family":"Kelmer","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery"},{"name":"Hospital of the University of Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3937-4029","authenticated-orcid":false,"given":"Georgios S.","family":"Sioutas","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery"},{"name":"Hospital of the University of Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie","family":"Ostmeier","sequence":"additional","affiliation":[{"name":"Stanford University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alex","family":"Hoang","sequence":"additional","affiliation":[{"name":"Baylor College of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4227-0378","authenticated-orcid":false,"given":"Gustavo","family":"Cortez","sequence":"additional","affiliation":[{"name":"Lyerly Neurosurgery"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1054-9414","authenticated-orcid":false,"given":"Kareem","family":"El Naamani","sequence":"additional","affiliation":[{"name":"Thomas Jefferson University Hospitals"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rawad","family":"Abbas","sequence":"additional","affiliation":[{"name":"Thomas Jefferson University Hospitals"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo","family":"Hanel","sequence":"additional","affiliation":[{"name":"Lyerly Neurosurgery"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omar","family":"Tanweer","sequence":"additional","affiliation":[{"name":"Baylor College of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Visish M.","family":"Srinivasan","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery"},{"name":"Hospital of the University of Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pascal","family":"Jabbour","sequence":"additional","affiliation":[{"name":"Thomas Jefferson University Hospitals"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Kan","sequence":"additional","affiliation":[{"name":"University of Texas Medical Branch Galveston"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian T.","family":"Jankowitz","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery"},{"name":"Hospital of the University of Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1055-8000","authenticated-orcid":false,"given":"Jeremy J.","family":"Heit","sequence":"additional","affiliation":[{"name":"Stanford University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan-Karl","family":"Burkhardt","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery"},{"name":"Hospital of the University of Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,4,13]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.3390\/gels9050378"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00062-021-01066-6"},{"key":"e_1_3_2_4_2","first-page":"172","article-title":"Brain AVM embolization with onyx","volume":"28","author":"Rooij WJv","year":"2007","unstructured":"Rooij WJv, Sluzewski M, Beute GN.
