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.

01:11Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
