In plain language
Across 44 endovascular aortic repairs, first operators received about four times the dose of second operators, and the most dose during complex fenestrated or branched repairs. Higher dose area product, more contrast and steep left-anterior angulation predicted higher operator dose.

What it found
First operator dose was significantly higher during fenestrated/branched repair (FEVAR) than during endovascular aneurysm repair (EVAR) or thoracic endovascular aortic repair (TEVAR).
Key figures: 0.34 ± 0.28 mSv (FEVAR) vs 0.11 ± 0.21 mSv (EVAR) and 0.06 ± 0.05 mSv (TEVAR); p = 0.003
First operators received about four times the dose of second operators; other staff received lower doses.
Key figures: FO 0.17 ± 0.21 mSv; SO 0.042 ± 0.045 mSv; RT 0.019; SN 0.017; AN 0.006; NSN 0.004 mSv
First operator dose correlated with procedural dose area product and iodinated contrast volume.
Key figures: Dose-area product (DAP) R = 0.69, p < 0.001; contrast R = 0.67, p < 0.001
Left-anterior C-arm projections greater than 60° were associated with higher first operator dose; fluoroscopy time correlated only weakly.
Key figures: p = 0.02; fluoroscopy time R = 0.40, p = 0.049
Second operator and anesthesiologist doses were strongly correlated with first operator dose.
Key figures: p = 0.003 and p < 0.001
Limits to keep in mind
Small single-series study of 44 procedures using a single over-lead chest dosimeter per person, so doses to unshielded areas such as the lens and hands were not captured; only apron and thyroid collar were used, and the country and centre are not stated in the abstract.
