Abstract:
Objective To evaluate the category of the variations on bilateral renal artery and clinical significance with 64-slice spiral CT angiography. Methods CT angiography of 250 patients were retrospectively analyzed. The variations on bilateral renal artery were observed and classified. Results According to the number of the main renal artery, the anatomy of renal artery was classified and typed in details. The incidence of the variations on renal artery in the patients and kidneys was 39.20% (98/250) and 22.80% (114/500), respectively. The incidence of early branch of the main renal artery and accessory renal artery was 9.60% (48/500) and 11.80% (59/500), respectively. No statistical difference of variation incidence was found between male and female, nor between left and right kidneys. The incidence of unilateral and bilateral variations on renal artery was 32.80% (82/250) and 6.40% (16/250), respectively, and the combinations of the latter were multiform. Conclusion Anatomical variations on renal artery can be showed clearly with 64-slice spiral CT angiography. Variations on bilateral renal artery are important to select the donor in case of renal transplantation.
