Variations in the origin of arteries in the abdomen are very common but with the invention of new operative techniques within the abdominal cavity, the anatomy of abdominal vessels has assumed much more clinical importance. During routine dissection of the abdominal cavity, we came across multiple arterial anomalies involving testicular and suprarenal arteries. On the right side, there was double testicular artery (medial and lateral) and the right inferior suprarenal artery aroused from the medial testicular artery. The right inferior phrenic artery (IPA) and middle suprarenal artery took origin from a common trunk just above the origin of right renal artery (RRA). On the left side, the left testicular artery was arching over the lower tributary of the left renal vein proper (LRVP). Apart from the developmental and morphological interest in arching gonadal arteries, they are of practical importance from a clinical and surgical viewpoint. The embryological and clinical significance of above variations has been described.
