Background
Variant renal arteries have been reported in 20~30% of the entire population. The anatomic variations among advanced patients should be investigated when performing surgery or interventional procedures on the kidney.
Most variant renal arteries originated from various level of the abdominal aorta. Very rarely, this case shows renal artery originated from the contralateral common iliac artery with other accessory arteries.
Case presentation
MDCT angiography revealed several anatomical variants of the right kidney. There were four right renal arteries. The main renal artery originated from the left proximal common iliac artery and other renal artery originated from the aortic bifurcation. The other two renal arteries arose from the abdominal aorta, lower thoracic T12 level and lower lumbar L4 level. The right kidney was located at the level of the third to fifth lumbar vertebra. And renal pelvis of the right kidney was laterally rotated.
Conclusion
This case documented a rare anatomic variant, involving multiple accessory renal arteries, including the main artery originating from the contralateral iliac artery, caused by a specific renal embryological condition. These variants should be analysed to effectively perform surgical and interventional procedures.

由对侧髂总动脉引起的右肾异位血管化
背景
据报道，20%~30% 的人群存在变异的肾动脉。在对肾脏进行手术或介入手术时，应调查晚期患者的解剖变异。
大多数变异肾动脉起源于腹主动脉的不同水平。极少数情况下，该病例显示肾动脉起源于对侧髂总动脉和其他副动脉。
案例展示
MDCT 血管造影显示右肾的几个解剖变异。有四个右肾动脉。主要肾动脉起源于左近端髂总动脉，其他肾动脉起源于主动脉分叉处。另外两条肾动脉起源于腹主动脉，下胸T12水平和下腰椎L4水平。右肾位于第三至第五腰椎水平。右肾肾盂横向旋转。
结论
该病例记录了一种罕见的解剖变异，涉及多个肾副动脉，包括起源于对侧髂动脉的主要动脉，由特定的肾胚胎状况引起。应对这些变体进行分析，以有效地执行外科手术和介入手术。
