Abstract

Introduction Because of the increasing number of fluoroscopically-guided interventional procedures, physicians may be exposed to high annual dose. Radioprotective equipment is therefore desirable.PurposeThis study aimed to evaluate the effect of a disposable lead-free drape in reducing scatter radiation exposure for physicians and patients during percutaneous coronary intervention.Materials and MethodsEye lens and extremity dose measurements, for CTO treatment, performed for about 70 procedures in two Belgian hospitals.Monte Carlo simulations performed with the MCNP-X code to investigate the influence of parameters such as beam projection, position of operator, shieldcombinations, drape shapes and position on the scatter radiation to staff and patient. Doses to selected organs, eye lenses, hands, elbows and legs were calculated.ResultsSimulations showed an effective dose reduction to the physician ranging from 2% to 36%, mainly observable for RAO projections; physician's hands were significantly affected (35% ÷ 80%). If the position of the pad is shifted upward by 5 cm the effective dose could be further decreased with 8%. Maximum 86%, 60% and 44% dose reductions were observed for the patient's genitalia, bladder and gonads, respectively.Measurements showed a significant (p
