Objective: The present study was aimed at evaluating the variations in extrarenal renal arterial vasculature in voluntary kidney donors who had undergone Multi-Detector Computed Tomography (MDCT) renal angiography for preoperative workup.
Methods: A retrospective hospital based cross-sectional study was carried out in a tertiary care Army hospital in Delhi from Jan 2019 to June 2020. All voluntary kidney donors included in the study underwent Multi-Detector Computed Tomography Angiography (MDCTA) of renal arteries as a part of routine pre-operative imaging protocol and were referred by the treating physician/surgeon for MDCTA study. Retrospective analysis of the image datasets was undertaken by the principal investigator and individual patient consent was waived off by the institutional Ethics committee.
Results: The mean age of study participants was 45.9±10.2 y. Accessory renal artery was relatively more common on left side (p-value 0.001). There was statistically no significant difference between gender and the presence of accessory renal artery. There was statistically no significant difference on the comparison of side and gender with distance of segmentary bifurcation of MRA. The orthogonal diameters at the origin of the MRA and accessory renal artery on both sides were also comparable. Origin of accessory renal arteries were caudal to MRA was more frequently seen. Early segmentary bifurcation of MRA was commoner on the right side.
Conclusion: The study emphasizes the importance of meticulous preoperative assessment, highlighting the need for surgeons to be cognizant of the potential variations in extrarenal renal artery anatomy. Such awareness is crucial for planning successful kidney transplant surgeries.
