Key result
EVAR anesthesia linked to nearly fourfold higher operator temple radiation exposure than interventional neuroradiology.
Why the study?
Medical radiation exposure increases the likelihood of cataract formation, but radiation exposure to anaesthetists during endovascular procedures is not well quantified.
Does radiation exposure to anaesthetists differ between endovascular aortic aneurysm repair and interventional neuroradiology procedures?
Population
77 anaesthetists during 45 endovascular aortic aneurysm repairs and 32 interventional neuroradiology procedures
Comparison
Anaesthetist radiation exposure during endovascular aortic aneurysm repair vs interventional neuroradiology
Design
Observational cohort study

Higher EVAR exposure may warrant targeted shielding; leaves open cumulative career risk for anaesthetists.

Does radiation exposure to anaesthetists differ between endovascular aortic aneurysm repair and interventional neuroradiology procedures?
Absolute Event Rate: 15% vs 4%
p-value: p=< 0.001
Radiation exposure to anaesthetists is significantly higher during endovascular aortic aneurysm repair compared to interventional neuroradiology, though both remain well below annual occupational limits.
Arii et al. (2014) conducted an observational in Endovascular procedures (n=77). Endovascular aortic aneurysm repair vs. Interventional neuroradiology was evaluated on Radiation exposure to the anaesthetist's temple (μSv) (p=< 0.001). Radiation exposure to the anaesthetist's temple was significantly greater during endovascular aortic aneurysm repair (median 15 μSv) than interventional neuroradiology (median 4 μSv, p < 0.001).
