Summary
Patient radiation exposure during neuroembolization is significant. Entrance skin doses (ESDs) in some cases exceeded thresholds for skin injuries, highlighting the need for radiation safety awareness.
Area of Science:
- Radiology
- Medical Physics
- Neurointerventional Surgery
Background:
- Neuroembolization procedures are increasingly common.
- Radiation exposure risks associated with neuroembolization are not widely recognized.
- Patient safety concerning radiation dose requires further investigation.
Purpose of the Study:
- To evaluate patient entrance skin dose (ESD) during neuroembolization procedures.
- To assess radiation exposure across multiple institutions performing neuroembolizations.
Main Methods:
- A study involving 103 neuroembolizations across 6 institutions.
- Patient ESDs were measured using caps with radiosensitive indicators.
- Clinical follow-up was conducted to monitor for scalp effects.
Main Results:
- Average fluoroscopic time was 67.1 minutes; average digital subtraction angiography frames were 883.
- Average maximum patient ESD was 1.9 Gy, with institutional averages ranging from 1.0 to 2.4 Gy.
- Radiation-induced epilation occurred in 6 patients.
Conclusions:
- Maximum ESDs during neuroembolization can surpass safe limits for skin injury.
- The findings underscore the importance of monitoring and managing radiation doses in neurointerventional procedures.
