Introduction: Radial artery occlusion may occur after percutaneous coronary intervention when done via transradial approach. The frequency of radial artery occlusion is almost nil in patients after PCI through transradial approach. Thus radial artery approach for PCI can be a good opportunity to conduct the procedure. Objective: To assess the frequency of radial artery occlusion after percutaneous coronary intervention through transradial approach in patients of acute coronary syndrome

Material & Methods Study Design: Descriptive case study Settings: Department of Cardiology, Punjab Institute of Cardiology, Lahore.

Duration: Six months i.e. 1st July 2020 to 31st December 2020. Data Collection: Total 100 patients who underwent PCI through transradial approach 6 months ago were studied. All the selected patients then underwent Doppler scan to assess patency of radial artery. Radial artery occlusion was confirmed by when there was reduced flow in radial artery as compared to the adjacent side artery

Results: In this study, the mean age of patients was 54.56 ± 8.96 years. There were 43 (43%) males and 57 (57%) females. The frequency of radial artery occlusion in patients after PCI through transradial approach was seen in 3 (3%) of the patients.

Conclusion: Results of this study demonstrates that the frequency of radial artery occlusion is almost nil in patients after PCI through transradial approach. Thus radial artery approach for PCI can be a good opportunity to conduct the procedure.
