The testicular arteries usually arise from the anterolateral aspect of the abdominal aorta just inferior to the renal arteries at the level of the second lumbar vertebra. However, they may also originate from the renal artery, middle suprarenal artery, one of the lumbar arteries, common or internal iliac artery, or the superior epigastric artery.
An unusual origin of the right testicular artery and an unusual course of the left one were observed during routine dissection of the retroperitoneal space of a 43-year-old male cadaver.
The right testicular artery originated from the inferior segmental branch of the right renal artery. After the left testicular artery originated from the anterolateral surface of the abdominal aorta just inferior to the left renal artery it was located between the left renal vein and the left renal artery and descended anterior to the renal vein. Thereafter it coursed on its normal route distally with the testicular vein.
Awareness of variations of the testicular arteries, such as that shown in this case, is important during surgical and radiological procedures pertaining to kidney.
睾丸动脉通常起自腹主动脉前外侧，恰在第二腰椎水平肾动脉下方。然而，它们也可能起源于肾动脉、肾上腺中动脉、腰动脉之一、髂总动脉或髂内动脉，或腹壁上动脉。
在对一名43岁男性尸体的腹膜后间隙进行常规解剖时，观察到右侧睾丸动脉的异常起源和左侧睾丸动脉的异常走行。
右侧睾丸动脉起源于右肾动脉的下段分支。左侧睾丸动脉起自腹主动脉前外侧，恰在左肾动脉下方，位于左肾静脉和左肾动脉之间，并在肾静脉前方下行。此后，它与睾丸静脉一起沿正常路径向远端走行。
了解睾丸动脉的变异情况，如本病例所示，在与肾脏相关的手术和放射学操作中很重要。
