Although transradial access has been associated with lower hospital costs for elective diagnostic and interventional neuroendovascular procedures, no study has compared transfemoral access and transradial access costs for a homogenous population of patients undergoing outpatient diagnostic cerebral arteriogram.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this single-center retrospective study, the Value Driven Outcomes database was used to evaluate treatment costs for patients who underwent outpatient diagnostic cerebral arteriogram from January 2019 to December 2022. Propensity-score matching was performed to reduce confounders.

Overall, per-visit costs were 15.2% cheaper for patients who underwent transradial access versus transfemoral access (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
