In plain language
In 179 stroke thrombectomies, the neurointerventionalist received a mean of 7.7 µSv per procedure, with higher doses linked to longer procedures, more fluoroscopy time and more passes. These are dosimeter readings, not health outcomes.

What it found
Mean neurointerventionalist dose per thrombectomy measured by real-time dosimetry
Key figures: 7.7 ± 7.4 µSv
Operator dose was associated with baseline stroke severity, puncture-to-recanalisation time, fluoroscopy time and number of passes
Key figures: NIHSS P = 0.043; puncture to recanalisation P = 0.003; fluoroscopy time P = 0.009; passes P = 0.009
Local patient dose reference levels (75th percentile) for thrombectomy were defined
Key figures: Dose-area product (DAP) 34 Gy cm2; cumulative air kerma 242 mGy; fluoroscopy time 12 min
Operator doses were higher than in the only prior study of operator dose in cerebral interventions, while patient reference doses were lower than previously published
Patient DAP was independently associated with patient body size, procedure duration, fluoroscopy time, number of passes, recanalisation success and aspiration technique
Key figures: weight P = 0.004; fluoro time P < 0.001; passes P < 0.001; aspiration P < 0.001
Limits to keep in mind
Single-centre data from an abstract only, with no detail on dosimeter placement or shielding used; operator dose reflects one dosimeter measurement per procedure rather than organ doses or health outcomes.
