Complex renal vascular variation: a case report.

As the number of renal surgical interventions increase a better understanding of the anatomy of renal arteries and their branches gain in importance. Here we describe a common trunk from the right side of the aorta ramifying into suprarenal and two renal hilar arteries in a 40-year-old male cadaver detected during dissections performed in a routine gross anatomy course. The suprarenal branch is divided into several smaller branches to supply blood to the suprarenal gland. The superior renal hilar artery gave rise to the right testicular artery and an additional suprarenal artery. The inferior renal hilar artery gave rise to one more additional suprarenal artery. The superior renal hilar artery crossed the inferior renal hilar artery. On the same side renal veins were also doubled. For better outcome interesting variations such as in this case should be kept in mind before and during any interventions involving this region.
