Abstract
OBJECTIVE: To describe pros and cons of some radiation protection measures and the implications on the design of a neurosurgery operating room.
MATERIAL AND METHODS: Concurring with the acquisition and use of an O-arm device, a structural remodeling of our neurosurgery operating room was carried out. The theater was enlarged, the shielding was reinforced and a foldable leaded screen was installed inside the operating room. Radiation doses were measured in front of and behind the screen.
RESULTS: The screen provides whole-body radiation protection for all the personnel inside the theater (effective dose <5μSv at 2,5 m from the gantry per O-arm exploration; 0,0μSv received behind the screen per O-arm exploration; and undetectable cumulative annual radiation dose behind the screen), obviates the need for leaded aprons and personal dosimeters, and minimizes the circulation of personnel. Enlarging the size of the operating room allows storing the equipment inside and minimizes the risk of collision and contamination. Rectangular rooms provide greater distance from the source of radiation.
CONCLUSION: Floor, ceiling and walls shielding, a rectangular-shaped and large enough theater, the presence of a foldable leaded screen, and the security systems precluding an unexpected irruption into the operating room during irradiation are relevant issues to consider when designing a neurosurgery operating theater.
