Comparison of Distal Transradial and Femoral Access in Endovascular Treatment of Non-coronary Arterial Disease

This study compared the efficacy and safety of distal transradial access (dTRA) and common femoral artery access (CFA) for endovascular treatment of non-coronary arterial disease. 102 interventions were divided into dTRA (n = 51) and CFA (n = 51) groups; the puncture success rate was 100% in both groups. The mean number of punctures and puncture time were greater in the dTRA than CFA group (1.86 vs 1.04 and 3.96 vs ≤1.00 min, p < .001 for both), whereas the access-related complication rate was comparable. The surgical success rate was higher in the CFA than dTRA group (98.0 vs 84.3, p = .036), and the operative time was longer in the dTRA than CFA group (99.09 vs 84.10 min, p = .017). The postoperative adverse event rate was not different between the dTRA and CFA groups. dTRA is a safe and feasible access for non-coronary arterial disease and is comparable to CFA in terms of puncture success, access-related complications, and major adverse events. The dTRA is inferior to CFA in the treatment of lower extremity arterial disease. Due to the increase in the operation time and the contrast medium volume in the dTRA, it is necessary to be vigilant about contrast nephropathy and late radiological random side effects.
