Contralateral transradial approach for carotid artery stenting: A feasibility study

Abstract

CAS using the contralateral transradial approach appears to be safe and technically feasible. The technique may be particularly useful in patients with right ICA lesions because of the favorable right CCA angle with the aortic arch.

The transradial approach for carotid artery stenting

“…In this study, the right radial artery was used in all cases as opposed the left radial artery technique described by Patel et al [7]. Right radial access provided adequate support even in acute angles of the common carotid artery with the arch of the aorta.…”

“…The benefits of transradial access for coronary interventions are well documented, and previous case reports and feasibility studies have demonstrated that transradial access may be an alternative strategy for carotid interventions, particularly in right internal carotid artery disease, bovine left internal carotid disease, or in patients with severe peripheral vascular disease [5–21]. Transradial access for nonbovine left internal carotid disease has been more challenging due to the unfavorable acute take off of the left common carotid [6, 7]. The purpose of this study is to review the experience of transradial carotid stenting at two high volume centers in order to determine the preferred technical transradial strategy for various types of carotid anatomy.…”

Transradial Neuroendovascular Treatment for Anterior Circulation Lesions: An Initial Experience with a 6 Fr Guiding Sheath

“…the success rate for right lesions was high. [8][9][10][11][12][13] However, according to some studies, when treating left lesions, a guiding system may be drawn into the aortic direction, which depends on the bifurcation angle of the left common carotid artery, making guiding impossible, or it may fall off during the procedure due to its instability. 11,13) In this study, we could navigate a 6 Fr guiding sheath into the common carotid artery using the right radial artery approach in all patients regardless of the left/right side of the targeted blood vessel, and accomplish neuroendovascular treatment postoperative complications.…”

Comparison of a Sheathless Transradial Access With Looping Technique and Transbrachial Access for Carotid Artery Stenting

“…Based on our previous study 8 and a report by Patel et al, 9 both the transradial and transbrachial approaches appear safe and feasible for CAS. However, a major limitation of the transradial approach (TRA) for CAS is the inability to use larger-sized guiding catheters because of the relatively small size of the radial artery.…”
