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.
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.
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.
变异肾动脉在全部人群中的报告发生率为 20%~30%。在对肾脏进行手术或介入操作时，应研究高级患者之间的解剖变异。大多数变异肾动脉起源于腹主动脉的不同水平。非常罕见的情况下，本例显示肾动脉起源于对侧髂总动脉，并伴有其他副肾动脉。
MDCT 血管造影显示右肾有几个解剖学变异。有四条右肾动脉。主肾动脉起源于左近侧髂总动脉，其他肾动脉起源于主动脉分叉处。另外两条肾动脉起自腹主动脉，T12 水平的下胸段和 L4 水平的下腰段。右肾位于第三至第五腰椎水平。右肾盂侧向旋转。
本例记录了一种罕见的解剖变异，涉及多支副肾动脉，包括源自对侧髂动脉的主动脉，这是由特定的肾胚胎发育条件引起的。这些变异应进行分析，以便有效地进行手术和介入操作。
