The Efficacy of Shielding Systems for Reducing Operator Exposure during Neurointerventional Procedures: A Real-World...

Area of Science:

• Medical Physics
• Interventional Radiology
• Occupational Health

Background:

• Neurointerventional surgery involves significant ionizing radiation exposure for patients and physicians.
• Reducing physician radiation exposure is critical but less studied than patient exposure.

Purpose of the Study:

• To evaluate the effectiveness of shielding systems in minimizing operator radiation exposure during neurointerventional procedures.

Main Methods:

• Prospective study comparing radiation exposure with and without a 3-part lead shielding system.
• A radiation protection drape was used in half of the cases.
• Two-way analysis of covariance controlled for procedure dose-area product.

Main Results:

• Lead shielding reduced operator exposure by 45% (P < .0001).
• Radiation drapes reduced exposure by 29% (P = .009).
• No significant difference between shielding and drapes; combined use offered no additional benefit.

Conclusions:

• Extensive lead shielding is recommended for neurointerventional surgery to maintain acceptable operator radiation levels.
• Radiation drapes are a viable alternative when lead shielding is impractical.
