A randomized study comparing the use of a pelvic lead shield during trans‐radial interventions: Threefold decrease in radiation to the operator but double exposure to the patient

Both groups were similar in BMI, procedures performed, and number of sequences. Usage of lead shielding statistically significantly reduced the radiation dose of the operator at all three sites measured: under lead apron all in µSv: 0.53 ± 1.4 vs. 0.17 ± 0.6, on thyroid collar 5.9 ± 7.7 vs. 2.9 ± 3.4, and left side of head 3.3 ± 3.4 vs. 2.1 ± 2.2, P<0.001. However the radiation to the patient was doubled from 15.4 ± 24.1 to 28.9 ± 81.1, P=0.04 CONCLUSIONS: The use of a pelvic lead shield during radial angiography reduced the operator radiation exposure at multiple measurement sites. However there was an increased exposure to the patient. This balance should be further investigated before the widespread adoption of this method. .
