Fig. 1. Time course of radial arterial diameter changes. No 

significant change in mean internal radial arterial diameter was 

observed between preprocedure and 1 day after procedure for 

either an initial procedure or a repeat procedure. The mean 

radial arterial diameter was 2.63 0.35 mm before the initial 

procedure and 2.51 0.29 mm 4.5 months after the first procedure 

1771 (P < patients 

0.05). No significant difference in radial arterial 

diameter changes was observed for patients receiving the di-

cases at 4 weeks, one case at 2 weeks); two cases had 

high SAR (0.91 and 0.93) and one case had small radial 

artery diameter (1.82 mm). Late recanalization of the 

occluded radial artery during the 12 weeks after procedure 

was not observed in three cases (Table III). 

at the time of repeated use, due maybe to the physician 

being skillful with radial artery puncture technique and 

catheter manipulation. Sakai et al. [10] have reported that 

the dropout rates for transradial approach (TRA) in- 

difficult to explain the mechanism of the vessel narrowing 

in our study, we demonstrated significant vessel 

narrowing after the transradial procedure during longterm 

follow-up. 

Considering recent increased concern of the radial 

artery as a grafting artery in coronary artery bypass 

grafts, radial artery occlusion or functional loss might be 

important problem in patients with transradial coronary 

procedures [14,15]. In our study, the frequency of radial 

artery occlusion was 0% and 2.6% after the initial and 

repeated procedure, respectively. Although it is difficult 

to find the factor of radial arterial occlusion due to low 

Ratio 0.68 ± 0.12 0.70 ± 0.12 ns 

incidence of radial artery occlusion, we could hypothe- 

size that the bigger size of arterial sheath might incite 

more injury to the arterial puncture site. In the repeated 

procedure, more PTCA was performed compared to the 

initial procedure (P 0.04). This relation might be 

inferred from the other findings; the radial arterial occlusion 

was very low (0.8%) in transradial coronary angiography 

with a 4 Fr catheter (0.8%) [5] and 2.8% for 

transradial coronary artery angioplasty using at least 6 Fr 

catheter in our data. The incidence of radial artery occlusion 

among 1,771 transradial coronary procedures 

during the same study period was 11 patients (0.6%). 

Therefore, radial artery occlusion was higher in repeateduse 

patients than in total first-use patients (2.6% vs. 

0.7%; P 0.01). Radial artery occlusion is similar to 

Nagai et al. [13] (2%), but less than Saito et al. [16] 

(6.8%). Saito et al. [16] included cases with high proportion 

of SAR higher than 1.1, in contrast to SAR of less
