PRESENCE OF RENAL ARTERY VARIATIONS AND ITS SURGICAL CORRELATION
Journal Title: International Journal of Medical and Clinical Research - Year 2012, Vol 3, Issue 5
Abstract
The paired renal arteries arise from the aorta just below the origin of the superior mesenteric artery and takes 20% of cardiac output. These are end arteries with no anastomoses. Variations in the number and arrangement of the renal vessels are extremely common. The so called aberrant or accessory arteries were in fact, normal segmental arteries. The arteries which had proximal origin at the hilum or in the pedicle were probably the result of a variation in the degeneration of the rete arteriosum while those from the aorta were persistent mesonephric arteries. The distal origin of the renal vessels could be explained by the persistence of earlier vessels which were supplying the kidneys when they were in sacral region. In the present study out of 184 kidneys 52 (28.2%) kidneys showed the presence of additional renal arteries. Out of 52 kidneys 34 kidneys had one additional artery, 18 kidneys had two additional arteries. The results are statistically significant. The presence of additional renal arteries was found unilaterally in 6 cadavers and bilaterally in 20 cadavers. In 23 kidneys additional artery towards the superior pole (Superior polar artery) was observed and in 29 kidneys inferior polar arteries were seen. With the increase in number of cases of kidney transplantation, living donar grafts have become major source for maintaining the donor pool, and the successful allograft with multiple arteries had become a necessity. Variations in the origin and course of the renal arteries occur frequently and are of special interest to the urologist with respect to the disease associated with it. Multi Detector Computer Tomography (MDCT), angiography and arteriography should be performed prior to every nephrectomy. It become’s mandatory for the surgeon to understand the abnormality or variations in the renal vasculature.
