Comparison of Radiation Dose and Contrast Dye Volume Comparison in Coronary Angiography Via Femoral and Radial Routes

Coronary angiography is a common procedure used to identify coronary artery disease. Whether femoral or radial vascular access is employed may impact radiation dosage and contrast dye utilization. This study examined radiation exposure and contrast dye volume in femoral and radial approach in patients undergoing coronary angiography. Objective: To assess and compare the radiation dosage and contrast dye volume between patients having coronary angiography through the femoral and radial routes. Methods: A prospective study included 408 consecutive coronary angiography patients from April 10 to August 31, 2023. The remaining 206 patients were treated radially, while 202 were treated femorally. We examined radiation exposure, dose area product (DAP), and contrast dye volume among groups. Results: Radial and femoral groups had similar mean ages (64.4±12.1 vs. 64.8±11.6, p=0.86). The radial group had 60.67% men versus 71.3% in femoral group. Radial and femoral catheterization radiation doses were 1.199 Gy (0.677-2.001) and 1.218 Gy (0.696-2.207), respectively, with a p-value of 0.88 showing no group radiation exposure difference. The group analysis found no hemorrhagic consequences from radial or femoral catheterization, coronarography, or angioplasty. Conclusions: The study participants noticed non-significant differences in contrast dye volume and radiation dose between femoral and radial coronary angiography.
