He reported on his new technique a year later, describing a radial artery cutdown in the upper third of the forearm, after which a 7-Fr to 9-Fr catheter was advanced in a retrograde fashion to perform a thoracic aortogram.1 It was not until over 4 decades later that the radial artery started to be accessed percutaneously, rather than through a cutdown, and for the purpose of cannulating the coronary arteries. In 1989, emboldened by the safety of the radial arterial line for critically ill patients, Dr. Lucien Campeau from Montreal Heart Institute described his experience of accessing the left radial artery for coronary angiography in 100 patients (90 men and 10 women).2 Primarily using a 5-Fr system, he was successful in cannulating the radial artery in 90% of patients, and reported only 2 complications, including a brachial artery dissection and a radial artery occlusion, neither of which were symptomatic. Three years later, in 1992, the first coronary stents were placed in 3 men via the right radial artery by Dr. Ferdinand Kiemeneij in Amsterdam.3 He attributed his ability to do this to “miniaturization” of coronary guiding catheters to 6-Fr and adequate crimping of a Palmaz-Schatz stent on a balloon to allow it to pass without becoming dislodged within the small guide.
