Prevalence of renal vascular variations: Evaluation with MDCT angiography

Abstract Background: Renal transplantation is the treatment of choice for people who suffer from end stage renal disease. Renal vascular anatomy is known for presenting a wide range of variations. Kidneys with variant renal vascular anatomy when used as a graft appear to be a potential risk factor that could impair the outcome of kidney transplantation. Information on renal vascular variations and its implication in the surgical outcome of renal transplantation has not been well studied. Hence, the present study was aimed to evaluate the outcomes of transplantation of renal allografts with variant renal vasculature as compared to allografts without renal vascular variation in the national kidney transplantation center of Ethiopia.Methods: A health institution based cross-sectional study was conducted. A retrospective review of the medical records of kidney recipients was performed. A total of 120 renal transplant recipient’s medical records were evaluated. Chi-square test and Independent t test was used to compare the surgical outcomes of renal transplantation. Graft survival was expressed using Kaplan-Meier curves, and was compared using the log-rank test. P values less than 0.05 was considered as statistically significant. Result: Evaluation of the renal transplant outcomes did not have shown a significant difference in the postoperative complication rate, rate of delayed graft function (DGF), creatinine clearance levels at 1 , 6, or 12 months postoperatively, and 1-year graft survival among recipients of allografts with and without renal vascular variations. However, operation time and the length of hospital stay were significantly longer among recipients of allografts with variant vasculature.Conclusion: No significant difference was noted in the outcomes of transplantation of renal allografts with and without vascular variations. Hence, renal allografts with vascular variations are safe to be recruited for transplantation as to this study.

Purpose: To assess the value of MDCT in evaluation of the anatomy of living kidney donors and in revealing the prevalence of renal vascular variations. Materials and Methods: This retrospective study was approved by the Ethics committee of Rajavithi hospital(NO.172/2555). The accuracy of the images of vessel structures obtained by using 64-row multidetector computed tomography (MDCT) angiography in comparison with the actual vessel structures observed during surgery was analyzed retrospectively. We analyzed 20 patients who had undergone donor nephrectomy from 2008 to 2012. Preoperative MDCT angiography was performed, and the surgeons themselves subsequently recorded the operative findings. Results: Nephrectomy was performed on the left side in all 20 patients. The accuracy levels of MDCT for the artery and the vein were 90% and 95% respectively. Conclusions: MDCT angiography is a good investigative technique for the preoperative evaluation of the anatomy of vessels.
