“…Similarly to our results, most of the studies reported that the incidence of RLRV variations was higher than that of CLRV variations (4,8,10,(13)(14)(15)(16). However, some studies found that the incidence of CLRV variations higher that RLRV variations (5,7,9,11).…”

“…Even though abdominal venous structures can be evaluated with different radiological modalities, such as CT, CT angiography, Doppler, MR and ultrasonography (USG), CT is the preferred imaging modality for the evaluation of abdominal venous vascular structures due to higher patient compliance, lower cost, fast and easy applicability and reliability (8,(10)(11)(12)(13).…”

Background: Left renal vein (LRV) variations occur in 0.8%-10.2% of the population.The most common LRV variations are retroaortic left renal vein (RLRV) and circumaortic left renal vein (CLRV). The purpose of this study is to determine the frequency of LRV variations in a large series on computed tomography (CT) and to investigate the association between LRV and malignancy development. examination of 12,341 (5,505 female, 6,836 male) patients was evaluated retrospectively in this study. Patients clinical and demographic data were recorded using the Hospital Information System.Results: LRV variations were detected in 314 (2.54%) of the 12,341 patients within the study. Of the 314 cases found to have LRV variations, 227 (1.84%) had RLRV, and 87 (0.70%) had CLRV. There was no statistical difference in total LRV variations (p = .083) and CLRV variation (p = .96) groups in terms of gender. However, the RLRV variation was found to be 1.32 times higher in males than in females (p = .039). Of the 314 patients with LRV variations, 73 (23.2%) had any sort of concomitant malignancy. Conclusions:A high incidence of malignancy was detected in patients with LRV variations. Of the LRV variations, RLRV variation is more common than CLRV variation. The presence of total LRV variations and CLRV variations is not associated with gender. Whereas the presence of RLRV variation is more common in the male gender.

“…Some anatomic variations in the renal veins may be correlated with clinical symptoms, as is the case of pain in the pelvic varices or varicocele. Furthermore, this multiplicity is more common in women than in men, as demonstrated by Arslan et al, Karazincir et al and Koc et al [20][21][22]., Therefore, description of the anatomic variations of the renal veins is necessary with regard to investigating the effects of these variations on hemodynamics and renal function, particularly in cases of surgical interventions in the retroperitoneal space [2], [23].…”

Context: Variations in renal vascular morphology are relatively common and involve both the renal arteries and the renal veins. Presence of supernumerary vessels is the variation most frequently encountered. Knowledge of such findings is valuable for urologists with regard to kidney transplantation, nephrectomy, vascular anastomosis, selective catheterization and many other surgical procedures on the kidneys. Objective: To report on a case of duplication of the right renal vein and its clinical and surgical implications. Case report: In one dissected specimen from a male cadaver, the presence of two right renal veins parallel to each other was observed in a position anteroinferior to the right renal artery. One vein emerged from the upper portion of the renal hilum, while the other emerged from the lower portion of the hilum. The two veins drained separately into the inferior vena cava, and neither of them received any tributaries. Conclusion: Knowledge of these vascular variations is important for urologists, vascular surgeons and radiologists, given that performing angiography prior to surgical interventions in the retroperitoneal space avoids complications, especially with regard to kidney transplantation.

“…Renal cysts and nephrolithiasis were the most frequently diagnosed conditions in patients with renal vascular variations, and these were considered to be due to negative effects of variations on renal function and hemodynamics. [14] Since retroaortic renal vein can be confused with retroperitoneal lymph nodes, differential diagnosis requires greater care in patients with renal neoplasms as in our case. [20] It is important to be aware of renal vein anomalies in retroperitoneal surgery, since failing to recognize these during surgery can result in bleeding, nephrectomy, and even death.…”

Variations of renal arteries and veins are of particular importance in the treatment of renal and renovascular conditions. Multiphase upper abdominal computed tomography of a 68-year-old male patient with renal cell carcinoma of right kidney revealed duplication of right renal artery and retroaortic left renal vein variation. Differential diagnosis should be made with great care in patients with renal neoplasms since variations may complicate diagnostic procedures. Here, we present a rare variation. Knowledge of variations accompanied by pathologies as in our case may be important as it can affect diagnostic and treatment procedures. The aim of this case report and literature review is to increase awareness about renal vascular variations among clinicians and oncologists who work in this field.Keywords: retroaortic left renal vein; right renal artery duplication; variation Anatomy 2015;9(2):91-93
