ABSTRACT
Introduction: The kidneys–the main organs of the excretory system, are supplied by a paired renal artery, originating from the Abdominal Aorta at the level of a disc between L1 and L2 and drained by a paired renal vein exiting from the hilum of the kidney to the Inferior vena cava.
Aim: To evaluate the morphology of renal vessels, their variations & clinical implications during renal surgeries in the subjects of the North India population by contrast-enhanced MDCT.
Materials and Method: The present study was conceptualized & carried out in the Department of Anatomy, in collaboration with the Department of Radiodiagnosis, Santosh Medical College & Hospital, Ghaziabad and from Dr. O.P Gupta Imaging Centre, Meerut. This study was performed on the 108 patients who were referred for abdominal CECT examination with suspected abdominal pathologies. Contrast-enhanced MDCT scan images of the Abdomen were reviewed for normal anatomy of renal vessels and their variants.
Result: Out of 108 patients, anatomical variations of the renal vessel were found in 72 (66.66%) patients. Variations of the renal artery were found in 56 patients (51.85%). Out of these 56 patients, 47 had supplementary renal artery, 17 had early branching of the renal artery and 8 patients had both supplementary and early branching of the renal artery. Supplementary renal arteries were seen in 15 patients on the right side, 16 patients on the left side & 16 patients bilaterally. Earlier branching of the renal artery was found in 9 patients on the right side, 10 patients on the left side and in 2 patients bilaterally. Variations of the renal vein were more commonly found on the right side, late renal vein confluence was seen in 28 (25.92%) patients and supplementary renal veins in 9 (8.3%) patients. On the left side, 2 (1.85%) patients had late renal vein confluence and 2 (1.85%) patients had retroaortic vein.
Conclusion: Variations of the renal artery are found frequently. Morphological evaluation of renal vessels is useful for planning and performing the endovascular, laparoscopic and urological procedure.
Key words: Renal artery (RA), Renal vein (RV), Supplementary Renal artery (SRA), Early branching (EB), Supplementary renal vein (SRV), Contrast-enhanced Multidetector Computerized Tomography (MDCT).
