Background:

  • Contrast nephropathy increases mortality by up to 30% post-angiography.
  • Risk-benefit assessment is crucial before contrast procedures.

Purpose of the Study:

  • To review strategies for preventing contrast nephropathy.
  • To evaluate the efficacy of various prophylactic measures.

Main Methods:

  • Literature review of studies on contrast nephropathy prevention.
  • Analysis of established and controversial prophylactic treatments.

Main Results:

  • Hydration and electrolyte correction are essential for all patients.
  • Acetylcysteine and theophylline pre-treatment are well-accepted strategies.
