However, in the prone position, conventional transfemoral arterial access is challenging, as the introducer sheath is positioned between the patient and the surgical table, impeding catheter maneuverability. This case series outlines the technical details and potential advantages of the transradial approach in patients undergoing cerebrovascular surgery in the prone position.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nCase 1 \u2013 A 55-year-old man was admitted with a subarachnoid hemorrhage. Cerebral angiography revealed a ruptured fusiform aneurysm at the origin of the left posterior inferior cerebellar artery (PICA). A hybrid surgical strategy consisting of an occipital artery-PICA bypass followed by endovascular internal trapping of the aneurysm was planned. Because the left radial artery puncture site was located on the dorsal surface near the operator with the patient in the prone position, catheter manipulation was more straightforward than with the conventional transfemoral approach. The procedure was completed without complications, except a cerebral infarction related to internal trapping. Case 2 \u2013 A 78-year-old man presented with a subarachnoid hemorrhage and was subsequently diagnosed with a craniocervical junction arteriovenous fistula. The draining vein was ligated with the patient in the prone position. Intraoperative cerebral angiography through the left radial artery confirmed complete shunt occlusion.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nThe transradial approach is technically advantageous in prone-position procedures in the HOR; it facilitates catheter manipulation during complex cerebrovascular surgeries.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_477_2025","type":"journal-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T06:02:40Z","timestamp":1758261760000},"page":"396","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Transradial catheterization for prone neurosurgical treatment in a hybrid operating room: Technical considerations"],"prefix":"10.25259","volume":"16","author":[{"given":"Taichi","family":"Ikedo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masakazu","family":"Okawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideo","family":"Chihara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Ikeda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeki","family":"Takada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeshi","family":"Funaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takayuki","family":"Kikuchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chiaki","family":"Sakai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiki","family":"Arakawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2025,9,19]]},"reference":[{"key":"10.25259\/SNI_477_2025\/ref-1","doi-asserted-by":"publisher","DOI":"10.1177\/15910199231212520","article-title":"Transradial versus transfemoral approach in cerebral angiography: A meta-analysis","author":"Batista","year":"2023","journal-title":"Interv Neuroradiol"},{"key":"10.25259\/SNI_477_2025\/ref-2","doi-asserted-by":"crossref","first-page":"490","DOI":"10.1080\/02688697.2019.1617403","article-title":"A hybrid operating room for combined surgical and endovascular procedures for cerebrovascular diseases: A clinical experience at a single centre","volume":"33","author":"Choi","year":"2019","journal-title":"Br J Neurosurg"},{"key":"10.25259\/SNI_477_2025\/ref-3","doi-asserted-by":"crossref","first-page":"e358","DOI":"10.1016\/j.wneu.2020.01.208","article-title":"Radial arterial access for thoracic intraoperative spinal angiography in the prone position","volume":"137","author":"Haynes","year":"2020","journal-title":"World Neurosurg"},{"key":"10.25259\/SNI_477_2025\/ref-4","doi-asserted-by":"crossref","first-page":"2018","DOI":"10.4244\/EIJ-D-17-00239","article-title":"A randomised comparison of incidence of radial artery occlusion and symptomatic radial artery spasm associated with elective transradial coronary intervention using 6.5 Fr sheathless eaucath guiding catheter vs. 6.0 Fr glidesheath slender","volume":"13","author":"Horie","year":"2018","journal-title":"Eurointervention"},{"key":"10.25259\/SNI_477_2025\/ref-5","doi-asserted-by":"crossref","first-page":"e731","DOI":"10.1016\/j.wneu.2024.04.159","article-title":"One-stage combined open and endovascular treatment using a hybrid operating room is safe and effective for distal middle cerebral artery aneurysms","volume":"187","author":"Kushi","year":"2024","journal-title":"World Neurosurg"},{"key":"10.25259\/SNI_477_2025\/ref-6","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1016\/j.surneu.2005.06.040","article-title":"Intraoperative angiography for neurovascular disease in the prone or three-quarter prone position","volume":"65","author":"Lang","year":"2006","journal-title":"Surg Neurol"},{"key":"10.25259\/SNI_477_2025\/ref-7","first-page":"43","article-title":"Brachial and antebrachial arterial patterns;
