In plain language

Across five Irish and Italian centres, patient radiation dose for standard endovascular aneurysm repair (EVAR) varied about sevenfold, and pooled data were used to propose an interim European reference level (15,849 μGym2). Staff dose was not measured.

the abstract

What it found

  • The pooled 75th percentile kerma-area product (PKA) across five centres, proposed as an interim European diagnostic reference level (DRL) for standard EVAR, was 15,849 μGym2.

    Key figures: 15,849 μGym2

  • Mean PKA varied roughly sevenfold between centres, from 4343 to 31,897 μGym2.

    Key figures: 4343 ± 994 μGym2 to 31,897 ± 5798 μGym2

  • Mean fluoroscopy times were long at all centres, ranging from about 708 to 972 seconds.

    Key figures: 708 ± 70 s to 972 ± 61 s

  • Mean number of acquisitions per procedure ranged from 4.74 to 10.38 across centres.

    Key figures: 4.74 ± 0.19 to 10.38 ± 1.54

Limits to keep in mind

Retrospective data from only five centres in two countries with 180 procedures; measures patient dose indices only, with no staff dose data, and abstract-only source.

How this summary was made

ORSIF prepared this summary with AI assistance from the abstract of the paper. A program then checked that the passage supporting each finding appears word for word in that source. A person has not yet reviewed each summary, so read the original before relying on a number. ORSIF summarizes research and does not endorse any product or company.
