Renal failure after major angiography can be avoided with hydration

Summary
A previous report suggested a 12% acute renal failure rate after angiography. This study found no renal failure in 537 patients when adequate hydration was maintained, challenging prior findings.
Area of Science:
- Nephrology
- Radiology
- Cardiovascular Medicine
Background:
- A previous report indicated a high incidence (12%) of acute renal failure following angiography.
- This rate was considered potentially excessive and warranted further investigation.
Purpose of the Study:
- To prospectively evaluate the incidence of renal failure after angiography.
- To determine if angiography poses a significant renal hazard, particularly when adequate hydration is maintained.
Main Methods:
- Prospective study design.
- Inclusion of 537 consecutive patients undergoing cerebral, abdominal, or peripheral angiography.
- Monitoring for instances of renal failure post-procedure.
Main Results:
- No cases of renal failure were observed in the 537 patients studied.
- The incidence of post-angiography renal failure was 0% in this cohort.
- Adequate hydration appeared to be a key factor in preventing renal complications.
Conclusions:
- Angiography, when performed with adequate hydration, does not present a significant hazard of renal failure.
- The previously reported high incidence of renal failure may have been an overestimation or related to different protocols.
- Maintaining hydration is crucial for patient safety during and after angiography procedures.
