Digital subtraction angiography for renal donor evaluation.

W H Cho, S C Jacobs, R K Lawson

    Summary

    Standard arteriography accurately identifies renal arteries in living related kidney donors. Digital subtraction angiography (DSA) is less accurate, making it unsuitable for pre-nephrectomy evaluation.

    Area of Science:

    • Nephrology
    • Vascular Imaging
    • Surgical Evaluation

    Background:

    • Accurate pre-operative assessment of renal vasculature is crucial for living related kidney donors.
    • Variations in renal artery anatomy can impact surgical planning and outcomes.

    Purpose of the Study:

    • To compare the accuracy of standard selective renal arteriography versus digital subtraction angiography (DSA) in evaluating renal artery anatomy in living related kidney donors.
    • To determine if DSA is a suitable alternative to standard arteriography for pre-donor nephrectomy assessment.

    Main Methods:

    • A series of 52 living related renal donors underwent preoperative angiography.
    • Preoperative angiographic interpretations were compared with intraoperative findings during donor nephrectomy.
    • Standard selective renal arteriography and digital subtraction angiography (DSA) were evaluated for accuracy in identifying the number of renal arteries.

    Main Results:

    • Standard selective renal arteriography demonstrated 100% accuracy in identifying single or multiple renal arteries.
    • Digital subtraction angiography (DSA) was 82% accurate, misidentifying the number of renal arteries in three of the five cases with multiple vessels.
    • Errors in DSA were attributed to inherent technological limitations.

    Conclusions:

    • Standard selective renal arteriography remains the gold standard for evaluating renal artery anatomy in living related kidney donors.
    • Digital subtraction angiography (DSA) is currently not accurate enough to replace standard arteriography for pre-donor nephrectomy evaluation due to its limitations in identifying multiple renal arteries.
