To guide the microcatheter to these ICA side branch feeders, the authors thought that a custom shaping of the intermediate catheter would be helpful to determine the direction of the microcatheter and strongly back it up. The aim of this study was to report the detailed methodology and clinical outcomes of patients who had undergone the embolization of ILT and MHT feeders using this method.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>METHODS<\/jats:title>\n<jats:p>This was a retrospective study of consecutive patients with intracranial tumors and dural arteriovenous fistulas (DAVFs) who had undergone endovascular embolization. The details of the embolization procedures were examined, especially the technique of guiding a low-profile microcatheter supported by the thermoformed intermediate catheter. The authors assessed the patient background, procedural outcomes, and postoperative complications.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>Between October 2013 and June 2022, 43 patients with intracranial tumors and 45 with DAVFs underwent embolization at the authors\u2019 institutions. Among these cases, embolization of the ICA side branch feeder was attempted in 10 intracranial tumors and 2 DAVFs. Of these 12 patients, the microcatheter was guided deep enough for successful embolization in 11 cases (92%). Two asymptomatic arteriovenous fistulas were complicated during guidewire manipulation deep in the feeder. Yet, both disappeared completely after glue injection into the feeding artery. No spasm or dissection of the parent artery occurred during the procedure. Postoperative radiological evaluation showed no intracranial hematoma or symptomatic cerebral infarction. One patient (9%) developed permanent postoperative cranial neuropathy that gradually improved after embolization.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>This study revealed that custom shaping of distal access catheters is an effective technique that enabled the embolization of ILT and MHT feeders with a success rate of more than 90%.<\/jats:p>\n<\/jats:sec>","DOI":"10.3171\/2023.4.jns23637","type":"journal-article","created":{"date-parts":[[2023,6,18]],"date-time":"2023-06-18T09:02:17Z","timestamp":1687078937000},"page":"194-200","source":"Crossref","is-referenced-by-count":4,"title":["Custom shaping of distal access catheter for navigation of microcatheter into inferolateral and meningohypophyseal trunk feeders"],"prefix":"10.3171","volume":"140","author":[{"given":"Yudai","family":"Hirano","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Teikyo University School of Medicine, Itabashi-ku, Tokyo;"},{"name":"Department of Neurosurgery, Faculty of Medicine, The University of Tokyo, Bunkyo-ku, Tokyo; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaaki","family":"Shojima","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Teikyo University School of Medicine, Itabashi-ku, Tokyo;"},{"name":"Department of Neurosurgery, Faculty of Medicine, The University of Tokyo, Bunkyo-ku, Tokyo; and"},{"name":"Department of Neurosurgery, Saitama Medical University, Saitama Medical Center, Kawagoe, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Uno","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Teikyo University School of Medicine, Itabashi-ku, Tokyo;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Koizumi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Faculty of Medicine, The University of Tokyo, Bunkyo-ku, Tokyo; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuta","family":"Oyama","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Teikyo University School of Medicine, Itabashi-ku, Tokyo;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Indo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Saitama Medical University, Saitama Medical Center, Kawagoe, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akira","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Saitama Medical University, Saitama Medical Center, Kawagoe, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soichi","family":"Oya","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Saitama Medical University, Saitama Medical Center, Kawagoe, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuhito","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Faculty of Medicine, The University of Tokyo, Bunkyo-ku, Tokyo; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Teikyo University School of Medicine, Itabashi-ku, Tokyo;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"1","key":"b1","series-title":"AJNR Am J Neuroradiol","first-page":"143","article-title":"Embolization of branches arising from the cavernous portion of the internal carotid artery","volume":"10","author":"Halbach VV","year":"1989","unstructured":"Halbach VV, Higashida RT, Hieshima GB, Hardin CW.
