If you are treated with angioplasty and stenting, the catheter used to open a block or narrowed artery, and in some cases to place a stent, is inserted in one of two arteries - the femoral, which is in the groin area, or the radial artery, which is in the wrist. Angioplasty performed from the radial artery is also called transradial angioplasty.
Both approaches are considered safe and effective for most patients in most circumstances. However, as with any medical procedure, the best approach is largely dependent on your unique medical and personal circumstances.
