Limitations of digital subtraction angiography in evaluating potential renal donors

Insights

Digital subtraction angiography missed an accessory renal artery in 17% of potential kidney donors. Conventional angiography is more reliable for evaluating renal arteries in kidney donors.

Area of Science:

  • Nephrology
  • Vascular Surgery
  • Radiology

Background:

  • Accurate assessment of renal artery anatomy is crucial for potential kidney donors.
  • Conventional angiography and digital subtraction angiography (DSA) are imaging modalities used for this evaluation.

Purpose of the Study:

  • To compare the diagnostic accuracy of conventional angiography and digital subtraction angiography in identifying the number of renal arteries in potential kidney donors.

Main Methods:

  • Six potential renal donors underwent evaluation using both conventional angiography and digital subtraction angiography.
  • The number of renal arteries to each kidney was determined by both imaging techniques.

Main Results:

  • Digital subtraction angiography demonstrated an error rate of 17%, missing one accessory renal artery in six patients.
  • Conventional angiography accurately identified all renal arteries in the evaluated donors.

Conclusions:

  • Digital subtraction angiography may underestimate the number of renal arteries in potential kidney donors.
  • Conventional angiography remains a more reliable method for pre-donation renal artery assessment.
