A novel lead attenuator to reduce operator exposure to scattered radiation in transradial coronary procedures

摘要

The harmful effects of radiation were soon recognised after the discovery of x-rays by Wilhelm Roentgen in 18951. Increased incidences of skin cancer and leukemia confirmed the carcinogenic potential of x-rays in the early twentieth century2. Interventional cardiologists experience frequent radiation exposure through fluor-oscopy. Interventional cardiology procedures performed via the radial approach are associated with longer fluoroscopy times and greater cumulative scatter radiation to the operator and staff. This approach is gaining popularity and exceeds 90% of cases in dedicated centres. The cumulative risk associated with a lifetime of exposure could become significant. The lower torso (from the umbilicus and down) acts as a source of scatter radiation to the operator and is not routinely shielded. We developed a uniquely designed, non-disposable lead attenuating material that could shield this region and significantly reduce the radiation scatter exposure to an operator in the catheterisation laboratory.
