However, it can be challenging to obliterate the shunted pouch if the microcatheter is not supported adequately.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>A 68-year-old woman presented with tinnitus and was diagnosed with multiple shunted DAVFs in the right transverse-sigmoid sinus (TSS) and the superior sagittal sinus (SSS). Although the entire sinus packing of the right TSS was performed, a follow-up angiography 7 months later revealed significant cerebral venous reflux due to occlusion of the left TSS and an increasing residual shunt flow in the venous pouch at the confluence of the SSS. A guiding catheter was introduced into the isolated sinus transvenously. Then, a steerable intermediate catheter (SIC) was manually steered into a hairpin shape and hooked on near the pouch prior to navigating a microcatheter into the fistula point. Finally, the fistula pouch was completely obliterated using only two coils under the adequate support of the turned-back intermediate catheter.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>The turn-back supporting technique using an SIC was useful in achieving SSO for DAVFs, providing both adequate support and guidance for the coaxial microcatheter.<\/jats:p>\n                    <jats:p>\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/thejns.org\/doi\/10.3171\/CASE24467\">https:\/\/thejns.org\/doi\/10.3171\/CASE24467<\/jats:ext-link>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case24467","type":"journal-article","created":{"date-parts":[[2024,11,4]],"date-time":"2024-11-04T01:45:35Z","timestamp":1730684735000},"source":"Crossref","is-referenced-by-count":1,"title":["Utility of the turn-back supporting technique using a steerable intermediate catheter: illustrative case"],"prefix":"10.3171","volume":"8","author":[{"given":"Takeshi","family":"Hara","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daizo","family":"Ishii","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Kondo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masashi","family":"Kuwabara","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobutaka","family":"Horie","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"4","key":"bib1","series-title":"J Neurosurg Sci","first-page":"437","article-title":"Natural history of brain arteriovenous malformations: systematic review","volume":"62","author":"Goldberg","year":"2018","unstructured":"Goldberg JRaabe ABervini D.
