BACKGROUND
Accessory renal artery (ARA) is the most common site for anatomical variation of renal supply artery. Rare studies reported interventional embolization for the management of massive hemorrhage caused by ARA injury after percutaneous kidney biopsy (PKB).
CASE PRESENTATION
We describe a 35-year-old man who developed massive hemorrhage after PKB leading to shock. Digital subtraction angiography (DSA) showed hemorrhage in the ARA at the inferior pole of the right kidney and hemostasis was noticed after renal artery embolization.
CONCLUSIONS
We proposed that much attention should be paid to the presence of ARA before PKB. In addition, digital subtraction angiography combined with superselective embolization is the best choice for the treatment of renal artery injury.
背景
副肾动脉（ARA）是肾脏供应动脉解剖变异最常见的部位。罕见的研究报道了经皮肾活检（PKB）后因 ARA 损伤导致大出血时的介入栓塞治疗。
病例介绍
我们描述了一位 35 岁男性，在 PKB 后发生大出血导致休克。数字减影血管造影（DSA）显示右肾下极的 ARA 出血，肾动脉栓塞后止血。
结论
我们提出，在进行 PKB 之前应高度重视 ARA 的存在。此外，数字减影血管造影结合超选择性栓塞是治疗肾动脉损伤的最佳选择。
