Summary
The radial approach for a coronary angiography has became popular in several centers because
of its simplicity and fewer complications. The radial artery occlusion (RAO) is the main
inconvenient and impose a limitation of future use of the radial artery as an access site for
catheterization in the future. Several strategies have been used to decrease the incidence of
RAO (heparin, patent hemostasis, etc). Nitrates in intra-arterial have been widely studied in
prevention of this spasm. Current data show that nitroglycerin intra-arterial at the end of
the procedure reduce the incidence of RAO. The hypothesis that use of nitroglycerin at the
start of catheterization would have the same effect was not tested.
