Data regarding operator radiation exposure related to radial versus femoral arterial access in patients undergoing percutaneous coronary intervention (PCI) remain controversial. This study sought to compare operator and patient radiation exposure during PCI with radial versus femoral access.
This study evaluated prospectively 542 patients between October 2014 and August 2016 undergoing PCI either using the radial or femoral access. In 74 pairs of propensity-score matched (PSM) patients, baseline characteristics, procedural data such as individual radiation to operator, fluoroscopy time, dose-area product (DAP) and Kerma-area product (KAP) were documented and analyzed. Personal radiation exposure to operator was measured by electronic dosimeter (Thermo Scientific, Siemens, UK)
After PSM, baseline and demographic characteristics were similar in the 2 groups. Table shows operator and patient radiation exposure. Radiation exposure to operator was 2-fold higher in radial compared with femoral access. Median fluoroscopy time was not significantly different in patients undergoing radial versus femoral access. Furthermore, mean cumulative DAP and KAP were also similar in radial and femoral PCI.
This PSM analysis from a contemporary cohort of patients undergoing PCI showed that radial access is associated with increased radiation exposure to the operators but with similar radiation exposure to the patient than femoral access. Improvement in radioprotection methods to the operators should be implemented for diminishing radial access associated radiation exposure.
