摘　　要：目的利用64层螺旋CT血管造影探讨肾动脉解剖变异的类型及双侧肾动脉解剖变异的临床意义。方法回顾性分析250例患者的肾动脉64层MSCTA影像资料,观察肾动脉的解剖变异并根据主肾动脉的数量对肾动脉解剖进行分类、分型。结果肾动脉解剖变异分别占病例数和肾脏数的39.20%(98/250)和22.80%(114/500),其中肾动脉提前分支和副肾动脉变异发生率分别为9.60%(48/500)和11.80%(59/500),性别、左右肾之间肾动脉变异发生率无显著性差异。单侧和双侧肾动脉解剖变异的发生率分别为32.80%(82/250)和6.40%(16/250),双侧肾动脉的解剖变异组合呈现多样性。结论64层螺旋CT血管造影可清晰显示肾动脉的解剖变异。双侧肾动脉解剖变异类型对于肾脏移植手术供肾的选择具有重要临床意义。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.
