A common trunk of origin of the right testicular and middle suprarenal arteries with a retrocaval course was observed during the dissection of a male cadaver. The Common trunk (CT) arose from the anterior aspect of the abdominal aorta (AA) at the level of the right renal artery (RRA) and after a short course behind the inferior vena cava (IVC), the CT divided into right testicular and middle suprarenal arteries. The middle suprarenal artery (MSA) passed upwards behind the IVC to the right suprarenal gland. The right testicular artery (RTA) descended posterior to the RRA and anterior to the IVC. It then continued on its normal route distally with the right testicular vein. The awareness of such variations of testicular and middle suprarenal arteries and their unusual origin and course might complicate the interpretation of angiograms and surgical procedures in the posterior abdominal area.
在一具男性尸体解剖过程中，观察到右侧睾丸动脉和肾上腺中动脉起源于一个共同主干，并走行于下腔静脉后方。该共同主干（CT）在右肾动脉（RRA）水平从腹主动脉（AA）前方发出，在经过下腔静脉（IVC）后方的一段短距离行程后，CT分为右侧睾丸动脉和肾上腺中动脉。肾上腺中动脉（MSA）向上经下腔静脉后方至右肾上腺。右侧睾丸动脉（RTA）在右肾动脉后方、下腔静脉前方下行。然后它与右侧睾丸静脉一起继续沿其正常路径向远端走行。了解睾丸动脉和肾上腺中动脉的这种变异及其不寻常的起源和走行，可能会使后腹部区域血管造影和外科手术的解读变得复杂。
