We used three-dimensional (3D) software, Siemens Aneurysm Analysis v.

The median duration to final follow-up was 365\u2009\u00b1\u2009184.0\u00a0days with all 35 patients having a mean modified Rankin Scale score of 0. One (2.9%) patient experienced a transient ischemic attack with hemiparesis perioperatively. A follow-up angiography revealed complete occlusion (WEB Occlusion Scale [WOS] A and B) in 25 (71.4%) of 35 patients and WOS C and D in 10 (28.6%) of 35. The median DAV ratio significantly differed between the groups. The median DAV ratios were 0.97 in the complete occlusion group and 0.84 in the WOS C and D group, respectively (<jats:italic>p<\/jats:italic>\u2009=\u20090.002). A receiver operating characteristic curve produced an area under the curve of 0.76 (confidence interval: 0.56\u20130.96). The optimal DAV ratio cut-off and the highest Youden index for complete occlusion was 0.90.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Calculating DAV ratios using 3D software may help improve the rate of complete occlusion following WEB treatment.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1007\/s00701-025-06558-9","type":"journal-article","created":{"date-parts":[[2025,9,13]],"date-time":"2025-09-13T06:39:22Z","timestamp":1757745562000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Optimal woven endobridge (WEB) device-aneurysm volume: using automated volumetric software to predict aneurysmal occlusion status after WEB treatment"],"prefix":"10.1007","volume":"167","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1669-4476","authenticated-orcid":false,"given":"Yosuke","family":"Kawamura","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomoji","family":"Takigawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaya","family":"Nagaishi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akio","family":"Hyodo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kensuke","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,9,13]]},"reference":[{"key":"6558_CR1","doi-asserted-by":"publisher","first-page":"695","DOI":"10.1177\/15910199211060970","volume":"28","author":"O Algin","year":"2022","unstructured":"Algin O, Corabay S, Ayberk G (2022) Long-term efficacy and safety of WovenEndoBridge (WEB)-assisted cerebral aneurysm embolization.
