Retrospective analysis finds dose metrics in stent-assisted coiling support patient safety, indicating potential standards.

Key Points

This research aims to evaluate radiation dose metrics and establish local diagnostic reference levels (DRLs) for stent-assisted coiling of intracranial aneurysms.
Performed a retrospective analysis on 132 stent-assisted procedures from 2018 to 2024.
Collected data on dose-area product (DAP), reference air kerma (Ka,r), fluoroscopy time (FT), and total DSA frames.
Established local DRLs by calculating 75th and 50th percentiles of collected data.
P75 values for DAP were 19.89 Gy·cm2, 332 mGy for Ka,r, 25 min 32 s for FT, and 354 DSA frames.
P50 values were 13.71 Gy·cm2 for DAP, 219.5 mGy for Ka,r, 20 min 36 s for FT, and 277 DSA frames.
Dose metrics for stent-assisted coil embolization are within the lower range of published values.
