Yes, I have seen radial artery approach many times. Our docs are warming up to it and we like the results. The benefits are the patient can sit up right away, bedrest time is practically nil, and outpatients can be discharged in a few hours if no intervention is done. It is much safer for obese patients. We have seen some pretty bad complications on obese patients using the femoral artery. If you make sure the allens test is ok, the risks are far less. We even use a special device to hold pressure on the radial artery that is a modified zip tie. The downside is it is more difficult for the doc to perform. The procedure is also usually longer for a radial approach. But overall, I heartily endorse it, especially for obese patients.
