Abstract:
Background: The distal transradial approach (dTRA) for coronary catheterization is a newly introduced alternative to the conventional transradial approach. This study investigated how many times the same distal radial artery can be cannulated for coronary catheterization. Methods: A total of 1717 patients underwent 2406 coronary catheterization procedures between April 2018 and March 2020. The dTRA was used as the primary approach whenever feasible in this study period, and the dTRA was used for 1555 patients (90.6%) and 2129 procedures (88.5%). Patients who underwent repeated coronary catheterization after the initial procedure using dTRA were included in this study. The incidence of successive application of dTRA in the same arm and the reasons for access site conversion were investigated. Results: A total of 430 patients were included in this study; of these, in 10 patients, the distal radial artery was cannulated on both sides in the initial procedure. The patient group included 320 men (74.4%), and the mean age was 72.2 ± 10.8 years. A 4-, 5-, or 6-French sheath or sheathless system was used in the initial procedure. A maximum of four successive coronary catheterization procedures, including the initial procedure, were carried out. The second procedure involved the distal radial artery on the same side in 394 cases (89.5%), and the fourth dTRA procedure was possible in 81.7% of the cases. Access site conversion during the follow-up procedure, which was observed in 57 cases, was attributed to radial artery occlusion (17.5%), narrowing of the distal radial artery (33.4%), tortuous route of the right upper limb approach (15.8%), and strategic reasons, such as aortography or coronary bypass graft angiography (15.8%). Conclusions: The dTRA was successfully applied in the same arm in 89.5% of the cases in the second procedure and 81.7% in the fourth coronary catheterization procedure.
