Stenosis, thrombosis, cannulation difficulty, infection, and access-related cardiac stress remain major sources of morbidity. This narrative review examines artificial intelligence and sensing technologies for vascular access care, based on PubMed and ClinicalTrials.gov searches through 22 August 2026 with citation chaining. Existing reviews have examined artificial intelligence in dialysis broadly or prediction models in isolation. In this review, the vascular access itself is kept as the unit of analysis, and the evidence is followed across four connected stages: systemic risk stratification; prediction of maturation, dysfunction, and complications from clinical, ultrasound, and multimodal data; longitudinal monitoring with optical, acoustic, vibration, thermal, and pressure sensors; and procedural support with robotics and visualization technologies. Reported discrimination is high in retrospective, recording-level analyses, reaching areas under the curve of 0.99 and sample-level accuracy of 100%, but falls to approximately 0.71 in longitudinal designs that predict future events in the same patients; patient-level external validation and calibration are also rarely reported. No approach has yet been demonstrated to reduce thrombosis, prolong patency, avoid interventions, or lower cost relative to standard care in prospective multicenter studies. Deployment is further constrained by power budgets, duty cycling, and transmission bandwidth in wearable devices. Technical feasibility should not be read as clinical utility.<\/jats:p>","DOI":"10.3390\/s26196089","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T14:36:34Z","timestamp":1790346994000},"page":"6089","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Artificial Intelligence and Sensing Technologies for Vascular Access in Hemodialysis: A Narrative Review"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9144-0647","authenticated-orcid":false,"given":"Concetto","family":"Sessa","sequence":"first","affiliation":[{"name":"Department of Nephrology and Dialysis, Maggiore \u201cNino Baglieri\u201d Hospital, 97015 Modica, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-6808-3598","authenticated-orcid":false,"given":"Elettra","family":"Lomeo","sequence":"additional","affiliation":[{"name":"Nephrology, Dialysis and Transplantation Unit, Department of Medical and Surgical Sciences, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-3153-2042","authenticated-orcid":false,"given":"Walter","family":"Morale","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Dialysis, Maggiore \u201cNino Baglieri\u201d Hospital, 97015 Modica, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-9927-8859","authenticated-orcid":false,"given":"Tito","family":"Gianni","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, PA 19107, USA"},{"name":"Department of Translational Medicine and Surgery, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bibiana","family":"Bonerba","sequence":"additional","affiliation":[{"name":"Nephrology, Dialysis and Transplantation Unit, Department of Medical and Surgical Sciences, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Grandaliano","sequence":"additional","affiliation":[{"name":"Nephrology, Dialysis and Transplantation Unit, Department of Medical and Surgical Sciences, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, 00168 Rome, Italy"},{"name":"Department of Translational Medicine and Surgery, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2882-4226","authenticated-orcid":false,"given":"Francesco","family":"Pesce","sequence":"additional","affiliation":[{"name":"Department of Translational Medicine and Surgery, Universit\u00e0 Cattolica del Sacro Cuore, 00168 Rome, Italy"},{"name":"Division of Renal Medicine, Ospedale Isola Tiberina\u2014Gemelli Isola, 00186 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"ii11","DOI":"10.1093\/ndt\/gfae131","article-title":"Global Structures, Practices, and Tools for Provision of Hemodialysis","volume":"39","author":"Htay","year":"2024","journal-title":"Nephrol.
