Usefulness of the minimally invasive flow reversal method in carotid artery stenting: Simplified flow reversal carotid artery revascularization for radial access (SF-CARR).

ABSTRACT: BackgroundFlow reversal, achieved by occluding both the common and external carotid arteries to induce retrograde flow from the internal carotid artery, is a useful method for preventing distal embolization in cases of carotid artery stenting (CAS). The "conventional method" 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 "simplified flow reversal carotid artery revascularization for radial access (SF-CARR)," 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.MethodsA retrospective study
