Preliminary Study on Retrograde Recanalization of Radial Artery Occlusion Through Distal Radial Artery Access: a Single-Center Experience

Purpose Radial artery occlusion (RAO) is an unresolved complication after transradial artery (TRA) puncture. The aim of this observational study was to assess the feasibility and safety of retrograde recanalization of RAO through distal transradial access (dTRA). Methods From June 2021 to March 2022, 28 consecutive patients with successful puncture and intubation through the dTRA in the anatomical snuffbox and RAO confirmed by angiography were enrolled. Results Among the 28 patients, 27 (96.4%) patients with RAO were successfully retrogradely recanalized through the dTRA and successfully underwent coronary angiography or coronary intervention. After the procedure, only 1 (3.7%) patient developed a forearm hematoma, and there were no other bleeding complications or nerve disorders. Conclusions DTRA is a safe and feasible approach for retrograded recanalization of RAO, with a high procedure success rate and few complications.
