Shunted pouches were identified using high-resolution cone-beam computed tomography and four-dimensional DSA. Embolization procedures were planned based on the tactile and spatial understanding provided by 3D-DSA and 3D-printed models. Five patients treated between 2018 and 2022 without 3D-printed models were used as controls.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Complete shunt obliteration was observed in all five patients whose CS was 3D-printed. Two patients were treated successfully with selective embolization of the shunted pouch alone and three patients required additional partial sinus packing. In the control group, selective embolization was possible in only one patient, and only two patients achieved complete obliteration, including one requiring retreatment due to early recanalization.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The use of 3D-printed models for CS DAVFs treatment may improve shunt point recognition and facilitate effective selective embolization.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/02841851251395712","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T16:56:31Z","timestamp":1785862591000},"page":"804-810","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Utility of 3D-printed models in preoperative simulation and spatial recognition for cavernous sinus dural arteriovenous fistulas"],"prefix":"10.1177","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8476-7721","authenticated-orcid":false,"given":"Hirotaka","family":"Sagawa","sequence":"first","affiliation":[{"name":"Institute of Science Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0695-4716","authenticated-orcid":false,"given":"Shoko","family":"Fujii","sequence":"additional","affiliation":[{"name":"Institute of Science Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyohei","family":"Fujita","sequence":"additional","affiliation":[{"name":"Institute of Science Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6969-8046","authenticated-orcid":false,"given":"Satoru","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Institute of Science Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sakyo","family":"Hirai","sequence":"additional","affiliation":[{"name":"Institute of Science Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1348-1099","authenticated-orcid":false,"given":"Kazutaka","family":"Sumita","sequence":"additional","affiliation":[{"name":"Institute of Science Tokyo"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,4]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-014-1474-4"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.3171\/2023.12.FOCUS23795"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.3171\/JNS\/2008\/109\/8\/0208"},{"key":"e_1_3_2_5_2","article-title":"Superselective shunt occlusion for the treatment of cavernous sinus dural arteriovenous fistulae","volume":"73","author":"Satow T","year":"2013","unstructured":"Satow T, Murao K, Matsushige T, et al.
