title: The efficacy and safety of transradial approach in comparison with transfemoral approach for coronary angiography and ad hoc coronary angioplasty in Thailand.
abstract: 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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
