Testicular arteries arise from the abdominal aorta and the inferior suprarenal artery from the renal artery. There are reports about variant origin and course of these arteries. Accessory testicular artery is also a common finding but its providing origin to inferior suprarenal artery is an important observation. During a routine dissection of abdomen of approximately 55-year-old male cadaver, unique vascular abnormality was observed. On the left side, a common arterial trunk originating from abdominal aorta immediately branched to give rise to superior testicular and inferior suprarenal arteries, the former after a short course hooked by the left suprarenal vein. In addition, the left suprarenal vein, second left lumbar vein, and left testicular vein joined to form a common trunk which drained into the left renal vein. A sound knowledge of vascular variations in relation to the kidney and suprarenal gland is important to surgeons dissecting the abdominal cavity.
睾丸动脉起自腹主动脉，肾上腺下动脉起自肾动脉。有关于这些动脉变异起源和走行的报道。副睾丸动脉也是常见发现，但其为肾上腺下动脉供血是一项重要观察结果。在对一名约55岁男性尸体进行腹部常规解剖时，观察到独特的血管异常情况。在左侧，一条起自腹主动脉的共同动脉干立即分支，形成睾丸上动脉和肾上腺下动脉，前者在短距离走行后被左肾上腺静脉钩绕。此外，左肾上腺静脉、左第二腰静脉和左睾丸静脉汇合形成一条共同干，注入左肾静脉。对于进行腹腔解剖的外科医生来说，了解与肾脏和肾上腺相关的血管变异知识很重要。
