Abstract

Transradial coronary intervention has been increased with the support of miniaturized angioplasty equipments. It is known to be associated with less bleeding and vascular complications than those of transfemoral approaches and the advantage of early ambulation. To assess the safety and efficacy of transradial approach, we compared the success and complication rates and procedural time for 51 transradial coronary interventions (26 stents, 25 balloon angioplasties) with 299 transfemorals interventions in 350 patients, who underwent coronary interventions in Chonnam National University Hospital between January and July 1999. Overall success rates for coronary interventions were not different between transradial and trans- femoral approaches (98.0% vs 95.3%). Procedural and fluoroscopic times for balloon angioplasty were 54.6+/-14.1 and 51.2+/-7.7 min in transradial and transfemoral approaches (P=0.19), and 12.0+/-5.2 and 11.9+/-3.0 min in each approaches (P=0.91). Those of stenting were 62.7+/-9.8 and 61.6+/-13.1 min (P=0.72), and 14.6+/-4.6 and 13.7+/-5.8 min (P=0.52) in transradial and transfemoral approaches. All procedures were done successfully without any major procedure-related complications (death, myocardial infarction, emergent coronary artery bypass graft). Major vascular complications were not developed in transradial intervention, but two cases of hematoma requiring transfusion developed in transfemoral intervention. Length of hospital stay was 3.43+/-1.28 days, which was shorter in transradial than that of transfemoral approaches (4.92+/-3.21 days, P=0.03), and one day of hospital stay was possible in 9 out of 51 patients (17.6%) in transradial approaches. Transradial approach for coronary intervention will be one of useful and feasible rotes for coronary interventions without major complications.
