Phantom study on radiation protection with the L-shaped lead drape for cardiac IVR operators

Trans radial access for cardiac catheterization is associated with reduced complications and improved patient comfort. Pelvic lead shielding of the patient has been reported to reduce operator radiation exposure. We tested the hypothesis that the originally developed L-shaped lead drape would reduce operator exposure using the human phantom. Scatter radiation was measured at the operator's position with an ionization chamber survey meter, with and without the L-shaped lead drape. At the operator's standing position, scatter radiation was reduced by up to 87%, as compared with that without. Similarly, scatter radiation at the operator's hand position was reduced by up to 92%. The use of the L-shaped lead drape during radial approach reduced the operator exposure at multiple measurement sites. (author)
