Abstract 18071: Comparison of the Femoral vs. Radial Access in Relation to X-Ray Exposure From 14194 Patients With Diagnostic Cardiac
There is growing interest in radial access for diagnostic catheterization due to lower bleeding complications and shorter hospitalizations of patients. The influence of the radial access on radiation time and patient radiation exposure was evaluated only in small clinical studies. Aim of the present work was to evaluate radiation time, mean effective radiation exposure of the patient and effective radiation dose in a large cohort of consecutive patients referred for diagnostic cardiac catheterization.
Methods: We evaluated in a prospective register data from 14194 consecutive diagnostic cardiac catheterizations done as coronary angiogram together with/ without LV- study. All patients examined between 2006 and 2008 were evaluated. Radiation time and patient radiation exposure were measured, effective radiation dose was calculated.
Results: From 14194 coronary angiograms 10600 were done with LV study whereas 3594 were done without between 2006 and 2008 in our institution. In the group with LV study 8398 patients were examined via femoral access (f) and 2211 patients were done via radial access (r). Mean fluoroscopy time was 2.24 min in f compared to 3.52 min in r (p> 0.001). The mean patient radiation exposure (MR) and the effective radiation dose (eD) were significant lower in f than in r. (MR = 40,42 gy/cm<sup>2<reset> femoral vs. MR = 48,44 gy/cm<sup>2<reset> radial; (p> 0.001) eD = 8,49 mSv femoral vs. eD = 10,17 mSv radial; p> 0.001). In the group without LV study 2947 vs. 647 patients were examined by f vs r. Also in this group of patients similar findings were made regarding fluoroscopy time, MR and eD than in the group with LV study.
Conclusions: Coronary angiography via radial access leads to increased radiation exposures of patients and to an increase in fluoroscopy time even in a large patient population compared to femoral access.
