A case report on unilateral high up origin of a testicular artery with embryological review

High up origin of the left testicular artery was noted during routine dissection of an elderly male cadaver. Just after origin it was found to ascend upwards behind the left renal vein to arch over it, distal to the left suprarenal vein close to the hilum of the left kidney. Such an extensive unusual course of testicular artery seems to posses an immense anatomical, embryological and clinical relevance to study to help surgeons to avoid unintentional injury during renal operation. Compression of renal vein by such an artery can produce renal congestion with vice-versa effect on testicular atrophy. Simultaneous descent of testis with ascent of kidney can enlighten such a variation as detailed below.
