Radial route has been used for diagnostic angiography as well as therapeutic purpose i.e. Coronary angioplasty or PTCA i.e. Percutaneous Transluminal Coronary Angioplasty.  Through the same procedure as angiography, a wire is taken down to the coronary artery with blockage and put across the blockage. Then a balloon is inflated across the blockage to make appropriate place for stent. Following this a stent is deployed across the blockage which scaffolds the artery and prevents further recurrence of blockage in future.
