Hands off, the radial artery is mine!

Mounsey and Taggart make an excellent point in addressing the worse results of radial artery (RA) grafts after previous transracial catheterization (TRC). There is now ample evidence (including from our group) that TRC causes extensive damage to the vascular wall and profoundly affects the RA vasoreactivity.1,2 At present, it is unclear when or even if the morphologic and functional properties of RA grafts return to baseline after TRC, with some studies showing persistent endothelial damage several months after the endovascular procedure.
