In plain language
Across 41 aortic endovascular procedures, the main operator had the highest body, hand and leg doses, but assistant operators had higher eye lens doses, especially in complex fenestrated/branched and iliac branch repairs. Staff positioning matters even with full protective equipment.

What it found
The main operator received the highest radiation dose to the whole body, hands and ankles.
Eye lens dose was higher for the assistant operators than for the main operator.
Assistant operators faced a high exposure risk, mainly during fenestrated/branched endovascular aneurysm repair (EVAR) and EVAR with iliac branch.
Patient peak skin dose rose significantly with procedure complexity and was below the reading threshold for many standard EVAR cases.
Key figures: 24 patients below reading threshold
Other staff members received low doses; staff positioning is a key factor even with full personal protection.
Limits to keep in mind
Single-centre dosimetry study of 41 procedures with a mobile C-arm in an operating room, mostly standard EVAR; the abstract gives no dose values or statistics for staff.
