In plain language
In 52 transvenous embolizations for CSF-venous fistula at one center, patient reference air kerma exceeded 3 Gy in over half, driven mainly by lateral-plane use and case complexity. Staff dose was not measured.

What it found
Median patient dose indices for transvenous CVF embolization were high.
Key figures: Median kerma-area product (KAP) 288.3 Gy·cm²; median Ka,r 3.29 Gy
Local reference levels (75th percentile) were derived for all procedures and for single-level cases.
Key figures: Diagnostic reference levels (DRLs) KAP 515.7 Gy·cm², Ka,r 4.76 Gy; single-level Ka,r 3.23 Gy
More than half of procedures exceeded 3 Gy reference air kerma.
Key figures: 28/52 (53.8%)
Dose accrued mainly on the lateral plane and rose with body mass index (BMI), number of levels, and navigation/injection times; cone-beam computed tomography (CBCT) was not associated with higher dose.
No radiation skin injury was documented at follow-up.
Limits to keep in mind
Single-center retrospective study of 52 procedures measuring patient dose indices only; no staff dosimetry, and proposed mitigation strategies were not tested.
