Total Radial Artery Occlusion Following Transradial Access: Complete Recanalization via the Anatomical Snuffbox

Abstract

Radial artery occlusion (RAO) is a common complication of procedures requiring transradial access. While radial artery occlusion is most often asymptomatic, there is an elevated prevalence of ischemia in patients with inadequate palmar arch blood supply. Furthermore, treatment options for RAO remain severely limited. We describe a novel technique using distal transradial access in the anatomic snuffbox to recanalize a totally occluded thrombosed radial artery.
