"Snuffbox" radial access entails sheath insertion into the dorsal branch of the radial artery within the so-called anatomic snuffbox. The purpose of this report is to describe the technique and early experience in 50 visceral interventional procedures performed in 31 patients, which included liver embolotherapy, visceral arterial stent insertion, aneurysm embolization, and emergency embolization. In all cases, the procedures were successfully completed by using the snuffbox access, with a single case of asymptomatic pseudoaneurysm as the only access-related complication. Early experience showed that snuffbox radial access is technically feasible and represents a viable alternative to conventional radial access for visceral intervention procedures.
