The \u201cconventional method\u201d employed by our institute for CAS involves the use of one-way valves incorporated in a flow reversal system for rapid manual blood aspiration. Subsequently, we recently transitioned from the conventional method to the \u201csimplified flow reversal carotid artery revascularization for radial access (SF-CARR),\u201d in which external carotid artery occlusion is omitted while a transradial approach is implemented. This study aimed to clarify the efficacy and safety of SF-CARR in patients undergoing CAS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective study was conducted in 50 patients diagnosed with internal carotid artery stenosis between 2022 and 2025.
