Introduction - The knowledge of the commonest pattern of the arterial supply of the abdomen and the deviants thereof is mandatory in various diagnostic, interventional and surgical procedures.
Methods - Multiple variations in the origin of the lateral branches of the abdominal aorta were observed during the routine dissection of the abdominal cavity in an adult male cadaver in the Department of Anatomy, Govt. Medical College, Amritsar.
Results – The variations encountered during the dissection were-
1) Double renal arteries were seen on the left side.
2) Double testicular arteries were seen on the left side, with the superior testicular artery arising from the inferior renal artery and the inferior testicular artery arising directly from the abdominal aorta.
3) Triple renal arteries were seen on the right side.
4) The right inferior phrenic artery was found to originate from the celiac trunk and the left inferior phrenic artery was found to arise directly from the abdominal aorta.
Conclusions - Accessory renal arteries may constitute a danger in nephrotomy and in the partial resection of the kidney. The presence of triple renal arteries is infrequent, with a reported incidence of 1-2%. A gonadal artery originating from an inferior renal artery may be injured during the percutaneous treatment of the syndrome of pelvi-ureteral junction and so it may become a major contraindication. Also, this anatomical variation enhances the importance of arteriography or the Doppler ultrasound examination of the renal hilum.
