A Comparison of Three-Dimensional Spiral Computed Tomoangiography with Renal Angiography in the Live-Donor Work-up

Abstract

The purpose of this study was to investigate the safety and efficacy of three-dimensional spiral computed tomoangiography (3-D spiral CTA) of the abdomen as a substitute for renal angiography in the evaluation of potential live kidney donors. Two of 10 potential live renal donors underwent 3-D spiral CTA only, whereas the remaining 8 underwent 3-D spiral CTA and renal angiography before transplantation. 3-D spiral CTA and renal angiography results were compared and correlated with intraoperative findings. In all 8 cases in which 3-D spiral CTA and renal angiography were compared, the number of arteries was correctly identified by both modalities. In this limited study, 3-D spiral CTA provided the same information as did angiography. According to these findings, 3-D spiral CTA might be used as an alternative to renal angiography, though a larger series is needed to determine whether it could replace renal angiography for all potential live-donor WOrk-ups.
