Summary based on

the abstract

What it found

• Fixed C-arm EVAR procedures had more than three times the dose-area product of mobile C-arm procedures.

  Key figures: 49.93 ± 38.06 Gy·cm2 (mobile) vs 168.34 ± 146.92 Gy·cm2 (fixed); P < .0001

• Fixed C-arm use required less contrast agent.

  Key figures: 108.55 ± 42.28 mL vs 85.37 ± 38.79 mL; P = .0014

• Fluoroscopy time did not differ significantly between groups.

• Proximal landing zone identification and main body deployment used the most radiation.

  Key figures: 24% of total dose

• Digital subtraction angiography accounted for nearly half of exposure.

  Key figures: 47.6%

Limits to keep in mind

Non-randomized single-centre comparison of patient dose-area product only; no staff dosimetry was measured, and phase analysis was available only from the fixed system. Country not stated in the abstract.
