{"doi":"10.3174/ajnr.a6953","title":"Anatomic Snuffbox (Distal Radial Artery) and Radial Artery Access for Treatment of Intracranial Aneurysms with FDA-Approved Flow Diverters","abstract":"<h3>BACKGROUND AND PURPOSE:</h3> Transradial access for neurointerventional procedures has been proved a safer and more comfortable alternative to femoral artery access. We present our experience with transradial (distal radial/anatomic snuffbox and radial artery) access for treatment of intracranial aneurysms using all 3 FDA-approved flow diverters. <h3>MATERIALS AND METHODS:</h3> This was a high-volume, dual-center, retrospective analysis of each institution’s data base between June 2018 and June 2020 and a collection of all patients treated with flow diversion via transradial access. Patient demographic information and procedural and radiographic data were obtained. <h3>RESULTS:</h3> Seventy-four patients were identified (64 female patients) with a mean age of 57.5 years with a total of 86 aneurysms. Most aneurysms were located in the anterior circulation (93%) and within the intracranial ICA (67.4%). The mean aneurysm size was 5.5 mm. Flow diverters placed included the Pipeline Embolization Device (Flex) (PED, <i>n</i> = 65), the Surpass Streamline Flow Diverter (<i>n</i> = 8), and the Flow-Redirection Endoluminal Device (FRED, <i>n</i> = 1). Transradial access was successful in all cases, but femoral crossover was required in 3 cases (4.1%) due to tortuous anatomy and inadequate support of the catheters in 2 cases and an inability to navigate to the target vessel in a patient with an aberrant right subclavian artery. All 71 other interventions were successfully performed via the transradial approach (95.9%). No access site complications were encountered. Asymptomatic radial artery occlusion was encountered in 1 case (3.7%). <h3>CONCLUSIONS:</h3> Flow diverters can be successfully placed via the transradial approach with high technical success, low access site complications, and a low femoral crossover rate.","journal":"American Journal of Neuroradiology","year":2021,"id":175071,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":22,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9604,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":583420,"name":"Sudhakar R Satti","orcid":"0000-0001-6671-7918","position":1,"is_corresponding":false},{"id":583421,"name":"Tim Eden","orcid":"0000-0002-2237-9846","position":2,"is_corresponding":false},{"id":715399,"name":"K de Macedo Rodrigues","orcid":"0000-0002-3649-102X","position":3,"is_corresponding":false},{"id":715400,"name":"Jasmeet Singh","orcid":"0000-0002-0843-0481","position":4,"is_corresponding":false},{"id":715401,"name":"Francesco Massari","orcid":"0000-0003-1479-078X","position":5,"is_corresponding":false},{"id":401593,"name":"Matthew J.
