In a 9-day-old patient with a choroidal type vein of Galen malformation we encountered an extremely tortuous posterior choroidal artery pedicle during endovascular treatment. After attempted selection using a traditional over-the-wire technique, we advanced a platinum coil through the micro-catheter. High flow within the feeder directed the soft and malleable coil anterograde. We then advanced the catheter over the coil\u2019s pusher wire in a facile manner to an ideal position for embolisation. This approach may be especially useful in cases requiring coil\/vinyl-based liquid embolics, given that the only flow-directed micro-catheter available to most operators is compatible with n-Butyl cyanoacrylate alone. Moreover, the soft distal portion of coil may impart a safety benefit over traditional guidewires in easily perforated neonatal vasculature.<\/jats:p>","DOI":"10.1136\/bcr-2019-231549","type":"journal-article","created":{"date-parts":[[2019,9,5]],"date-time":"2019-09-05T08:07:57Z","timestamp":1567670877000},"page":"e231549","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Flow-directed micro-catheterisation technique over a detachable coil"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2714-3787","authenticated-orcid":false,"given":"Henrik","family":"Ullman","sequence":"first","affiliation":[{"name":"Department of Radiology, UCLA Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesse","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Radiology, UCLA Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoki","family":"Kaneko","sequence":"additional","affiliation":[{"name":"Department of Radiology, UCLA Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Tateshima","sequence":"additional","affiliation":[{"name":"Department of Radiology, UCLA Medical Center, Los Angeles, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,9,4]]},"reference":[{"key":"2025082711425762000_12.9.e231549.1","first-page":"444","article-title":"Evolution of treatment options for vein of Galen malformations","volume":"6","author":"Khullar","year":"2010","journal-title":"J Neurosurg"},{"key":"2025082711425762000_12.9.e231549.2","doi-asserted-by":"crossref","first-page":"469","DOI":"10.1093\/neuros\/nyy100","article-title":"Vein of galen aneurysmal malformation: advances in management and endovascular treatment","volume":"84","author":"Berenstein","year":"2019","journal-title":"Neurosurgery"},{"key":"2025082711425762000_12.9.e231549.3","first-page":"929","article-title":"Arteriovenous malformation nidus catheterization with hydrophilic wire and flow-directed catheter","volume":"18","author":"Aletich","year":"1997","journal-title":"AJNR Am J Neuroradiol"},{"key":"2025082711425762000_12.9.e231549.4","doi-asserted-by":"publisher","DOI":"10.1148\/132.3.619"},{"key":"2025082711425762000_12.9.e231549.5","first-page":"1068","article-title":"Progressive Suppleness Pursil Catheter: a new tool for superselective angiography and embolization","volume":"10","author":"Dion","year":"1989","journal-title":"AJNR Am J Neuroradiol"},{"key":"2025082711425762000_12.9.e231549.6","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(94)71528-1"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-231549","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T18:43:01Z","timestamp":1756320181000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-231549"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,9]]},"references-count":6,"journal-issue":{"issue":"9","published-online":{"date-parts":[[2019,9,4]]},"published-print":{"date-parts":[[2019,9]]}},"alternative-id":["10.1136\/bcr-2019-231549"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-231549","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,9]]}}}
