Objective : To assess the efficacy and safety of transradial approach compared with transfemoral approach for coronary
angiography and ad hoc angioplasty in Phramongkutklao hospital at the time of initiation of transradial program.
Material and Method: Prospective data collection of consecutive patients who underwent coronary angiography with ad hoc
angioplasty during October 2004 to January 2005 was conducted. Baseline demographic data and the details of the procedure
were recorded. The complications were assessed by a single doctor using standard protocol.
Results : There were 75 included in our study. Transradial approach and transfemoral approach was performed in 23 cases
(30.7%) and 52 cases (69.3%), respectively. The baseline characteristics, procedure results were similar, except the there
was higher prevalence of NST-ACS symptoms (92.31% vs. 65.22%, p = 0.004) and access site complications in transfemoral
group (23.08% vs. 4.35%, p = 0.035). The success rate was very high (> 90%) and not significantly different in both groups.
However, the transradial group was associated with lower assess site complications earlier ambulation and better patient’s
satisfaction.
Conclusion : Even at the time of initiation of transradial program, transradial approach for coronary angiography and ad
hoc angioplasty can be performed with similar efficacy, less local complication, earlier ambulation and better patient’s
satisfaction compared to the standard transfemoral approach.
