Change in the diameter of the radial artery transradial intervention using a 6 French system in Japanese patients.
We examined the change in the diameter of the radial artery after transradial intervention (TRI) using a 6 French system in 50 Japanese patients in order to investigate whether the radial artery would be preserved after TRI. In all cases, the Allen test was normal and repeated puncture was possible at the TRI site 3 months after TRI. Moreover, the appearance of new stenosis or thinning throughout the radial artery at the TRI site was not seen. The diameter of the radial artery 3 months after TRI tended to be somewhat smaller at both the proximal and distal sites; however, there was not a statistically significant change between the diameter before and 3 months after TRI. Our results show that the radial artery will be preserved after TRI using a 6 French system in selected Japanese patients.
