Transradial Interventions in Coronary Artery Disease: Comparison with Transfemoral Interventions


Transradial coronary intervention was introduced recently. It has less bleeding and vascular complications and advantage of early ambulation.
We compared 142 transradial coronary interventions (101 stents, 56 balloon angioplasty and 18 rotablation) with 120 transfemoral interventions in 230 patients from January to August 1998.
Overall success rate was not different between two approaches (92% vs 89%), but smaller sized sheath and less amount of contrast agent were required in transradial interventions compared to transfemoral interventions. Conventional guiding catheters which are used in transfemoral approach were used in most cases (94%) of transradial interventions. Judkins left 3.5 (in stead of JL4.0 in femoral approach) and Judkins right 4.0 were the most frequently used guiding catheters in transradial approach. Stent implantation was successfully done in 99 out of 101 lesions (98%) in transradial intervention and 76 out of 78 lesions (97%) in transfemoral intervention. Rotational atherectomy and primary balloon angioplasty or stenting were done successfully in 10 - 20% of the patients in both groups. All procedures were done successfully without any major procedure-related complications (myocardial infarction, death, bypass surgery) or major vascular complications in both groups. During the clinical follow-up of transradial group, punctured arteries showed 10% incidence of radial artery pulse weakness with 3% of pulse loss.
Transradial approach is useful another feasible route for coronary interventions. The feasibility of primary balloon angioplasty or stenting and rotational atherectomy by transradial approach should be evaluated in the future.
