Key result
Left snuffbox approach achieves successful 7-French PCI for CTO without bleeding complications.
Why the study?
Is the snuffbox approach using a 7-French sheath via repuncture of the distal radial artery feasible and safe for coronary chronic total occlusion intervention?

Is the snuffbox approach using a 7-French sheath via repuncture of the distal radial artery feasible and safe for coronary chronic total occlusion intervention?
This case highlights the feasibility of repuncturing the distal radial artery for a snuffbox approach using a 7-French sheath in complex PCI for chronic total occlusion.
Snuffbox 7-Fr access may enable complex CTO PCI without spasm; leaves open prospective trials before routine adoption.

Kim et al. (2019) conducted a case report in Coronary chronic total occlusion (n=1). Left snuffbox approach using a 7-French sheath was evaluated on Successful percutaneous coronary intervention without puncture-site bleeding complications. Percutaneous coronary intervention for a chronic total occlusion was successfully performed via the left snuffbox approach using a 7-French sheath without puncture-site bleeding complications.
