In plain language
Across 18 studies of elective endovascular aneurysm repair (EVAR), staff radiation doses varied widely. Operators' left eye and hand received more dose, and scrub nurses received more than circulating nurses. Image fusion, dual fluoroscopy with zoom and suspended shielding were associated with lower staff dose.

What it found
Occupational dose during EVAR varied widely across the 18 included studies.
Key figures: ED 0.40 to 4350.00 μSv; Hp(3) 0.25 to 2500.00 μSv
Operator exposure was consistently higher on the left side for eyes and hands.
Key figures: left eye 200.00 vs right eye 30.00 μSv; left hand 76.90 vs right hand 46.70 μSv
3D image fusion reduced operator effective dose, and dual fluoroscopy with digital zoom lowered median doses.
Key figures: 55% to 66% (fusion); 62% (dual fluoroscopy with zoom)
Suspended lead shielding systems eliminated axillary exposure in some cases.
Supporting staff received lower but non-negligible doses; scrub nurses received more than circulating nurses.
Limits to keep in mind
Abstract only; included studies were observational and heterogeneous in dosimetric metrics and reporting, which prevented pooling, and the search was limited to 2019-2025 English-language publications.
