Comparison between the right and left radial approach in coronariography

Since the 1940s, various methods for creating vascular access have been described. In 1929 Werner Forssman who at the time was a surgical resident performs the first catheterization using a urinary catheter.1 In 1941 Fariñas described the passage of a urinary catheter through a trocar placed in the femoral artery to perform an aortography.2 In1947 Radner through a dissecting artery exposed the radial artery and performed a vertebral angiography. In 1949 Jönsson performed an aortography performing a puncture at the common carotid artery using a blunt cannula with a needle the cannula was inserted through a silver wire. In 1953 Dr. Sven Ivar Seldinger described a technique which consisted of performing a puncture using a stylet, subsequently a 3cm flexible guidewire was inserted, the needle was withdrawn and the vessel was compressed, at the meantime a catheter was passed through the flexible guide wire through the puncture site and finally the guidewire was withdrawn guide.3 Dotter and Judkins (who described femoral access for coronary angiography) in 1964 performed the first transluminal angioplasty in an 83-year-old patient, showing a decrease in temperature and pain of a pelvic limb and who refused to be amputated, they used a teflon-coated catheter to dilate the stenotic area.4,5 In 1977 Dr. Andreas Gruetzing performed the first successful coronary angioplasty in a human being, a ballon was mounted at his catheter.
