A common trunk of origin of the right testicular and middle suprarenal arteries with a retrocaval course.

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.
