Rotational atherectomy can be performed via the radial or femoral artery approaches with similar success rates. A study compared outcomes of 67 patients who underwent rotational atherectomy via the femoral approach to 52 patients who underwent it via the radial approach and found no significant differences in procedural characteristics, success rates, or in-hospital complications between the two groups except that pacing wires were inserted less often in the radial group. Overall, rotational atherectomy performed via the radial approach was found to be a feasible alternative to the femoral approach.
