In plain language

In 64 patients having abdominal aortic aneurysm repair, endovascular aneurysm sealing used about half the dose area product and screening time of standard endovascular aneurysm repair (EVAR). Staff dose was not measured, but shorter, lower-dose procedures may mean less exposure for the fluoroscopy team.

the abstract

What it found

  • Dose area product was about half as high with endovascular aneurysm sealing (EVAS) as with EVAR.

    Key figures: 54 (IQR 42, 77) vs 111 (IQR 75, 157) Gy∙cm(2); p<0.001

  • Screening time was shorter with EVAS than with EVAR.

    Key figures: 16 (IQR 14, 20) vs 32 (IQR 26, 38) minutes; p<0.001

  • Operating time was shorter with EVAS.

    Key figures: 121 (IQR 105, 146) vs 162 (IQR 145,186) minutes; p<0.001

  • Digital subtraction angiography (DSA) made up a larger share of dose-area product (DAP) in EVAS, though absolute DSA time was marginally lower.

    Key figures: 20% (IQR 15%, 28%) vs 14% (IQR 11%, 19%), p<0.001; 1.07 vs 1.19 minutes, p=0.037

  • DAP correlated moderately with screening, fluoroscopy and operating time.

    Key figures: ρ=0.597, p<0.001 (screening time); ρ=0.512, p<0.001 (operating time)

Limits to keep in mind

Small non-randomized comparison of consecutive patients using indirect patient dose indicators (DAP, screening time); no staff dosimetry was measured, and country and centre are not stated in the abstract.

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.
