Unusual branching and course of the testicular artery.

In a Turkish male, the right testicular artery was found to originate from the aorta at nearly the same level as and anterior to the renal artery. This testicular artery was seen to give off the inferior phrenic and superior suprarenal arteries. During its course the artery was posterior to the inferior vena cava. In addition to the above mentioned characteristics, the artery arose 5 mm below the renal vein and, after ascending to the superior border of the renal vein, arched over and descended in front of it to continue along its downwards course. This case implies that the lateral mesonephric arteries form anastomoses and that different arteries may interfere with each other's development. Another significant fact in this case is that the testicular artery crossed over the renal vein and descended anterior to it; a condition which may cause pathological disturbances.
