[Comparison between radial and femoral approaches in ad hoc coronary angioplasty].
Between September 1999 and June 2001, 591 patients required ad hoc coronary angioplasty. The authors compared the group of patients in whom the approach of first intent was radial (n = 328, 55%) with those in whom the femoral approach had been used (n = 263), in terms of immediate local (haematoma or thrombosis requiring surgical intervention or transfusion) and general complications (myocardial infarction, cerebrovascular accident), and major adverse cardiovascular events (infarction, angioplasty, bypass and death) at 1 year. The dose of ionising radiation during the procedures was also compared prospectively. The conversion rate from the radial (R) to the humeral or femoral (F) approach was 10%. The angioplasty, stenting, and stenting without dilatation failure rates were identical in the two groups (5% versus 5%, 0.6% versus 1.9%, 3% versus 4%, respectively). The average irradiation time was greater in the R group than in the F group (23 +/- 12 min vs 17 +/- 4 min, p < 0.001) as was the irradiation per surface unit (242 +/- 137 Gy.cm2 vs 185 +/- 117 Gy.cm2, p < 0.001). The immediate complication rate was comparable in the two groups (2.5% in group R vs 3.6% in group F) as was the major adverse cardiovascular event rate at 1 year (13% in both groups). The authors observed the same rate of immediate complications and late adverse cardiac events in patients undergoing coronary angioplasty followed by immediate angioplasty by the radial or femoral approaches with an acceptable conversion rate from the radial to the femoral approach. The procedures by the radial approach seem to be associated with a greater time and dosage of ionising radiation.
