Sheath size, radial occlusion, and ethnicity: Real or confounded?

Abstract

Key Points Japanese participants experienced higher incidence of radial artery occlusion when compared to non‐Japanese participants. The use of 6Fr Slender sheath was inferior for radial artery occlusion than 5Fr sheath in Japanese, but no different in non‐Japanese participants. Is not clear if this apparent ethnical interaction is real versus confounded, warranting more research in the area.
