Objectives - Review of the angiographic data of 118 live kidney donors was done to assess the renal vessel anatomy, compare the findings with the per operative findings, to determine the sensitivity of Multislice CT angiography in the work up of live potential donors and finally to discuss and compare the results of the present study with the reported results using single slice CT, MR and conventional angiography. Material and Methods : Retrospective analysis of the angiographic data of 118 of prospective live kidney donors was done. All donors underwent renal angiography on Multistice CT scan using 50 cc IV Contrast with 1.25 mm slice thickness followed by MIP and VRT post processing algorithms. The number of vessels, vessel bifurcation, vessel morphology and venous anatomy was analysed and the findings compared with the surgical findings. Results - MSCTA showed clear delineation of the main renal arteries in all the donors with detailed vessel morphology. The study revealed 100% sensitivity in detection of accessory renal vessels which had a overall incidence of 26.67% with commonest distribution in the parahilar region. Discussion- The present study showed 100% sensitivity in the visualization and detection of main and accessory renal vessels. These results were comparable with conventional angiography which has so far been considered the gold standard and were found superior to the use of SSCT, MR in the angiographic work up of liver renal donors. Due to improved detection of accessory vessels less than 2 mm in diameter a higher incidence of aberrant vessels was seen on the right side as has been suggested so far.
