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.

Is a Retroaortic Vein a Risk Factor in Laparoscopic Living Donor Nephrectomy?

et al. 2020

Introduction: In living donor transplantation choosing the right donor and donor side for laparoscopic donor nephrectomy is a challenging task in clinical practice. Knowledge about anomalies in renal blood supply are crucial to evaluate the feasibility of the operative procedure. Few data so far exist whether the existence of a retroaortic left renal vein has an impact on living kidney transplantation outcome for donor and recipient. Materials and Methods: We retrospectively analyzed 221 patients who underwent laparoscopic living donor nephrectomy between 2011 and 2017 for existence of a retroaortic left renal vein. Clinical characteristics and operative outcomes for donors and recipients were analyzed. Results: 221 patients underwent donor nephrectomy between 2011 and 2017; 11 patients (4.98%) showed the feature of a retroaortic left renal vein, and in 8 patients (72.7%) out of those 11 the left kidney was chosen for transplantation. Mean preoperative serum creatinine was 0.77 (0.49–0.98) mg/dL and 1.28 (0.97–1.64) mg/dL at discharge. In recipients mean serum creatinine preoperatively, after 1 week, 1 month,1 year, 2 and 3 years of follow-up was 10.36 (6.09–20.77) mg/dL, 1.71 (0.67–2.72), 1.33 (0.70–1.89), 1.31 (0.95–2.13), 1.31 (0.98–2.13) and 1.33 (1.03–1.84), respectively. Neither donors nor recipients suffered from any operative complications. Conclusions: Laparoscopic living donor nephrectomy of a left kidney with retroaortic renal vein is safe for the donor, without limitation in the outcome for the recipient.

Vena Cava and Left Renal Vein Variations and Association with Other Anomalies Including Horseshoe Kidney

Objectives: The purpose of this study was to detect the types and prevalences of vena cava variations, as well as looking for gender differences and associating anomalies. Patients and Methods: The computed tomography (CT) images of 5763 patients who had undergone thorax and abdominal CT examinations were evaluated retrospectively for superior vena cava (SVC), inferior vena cava (IVC), and left renal vein (LRV) variations. Results: Vena cava variations were detected in 637 (11%) patients. SVC variations were present in 15 (0.26%) patients, while 36 (0.64%) patients had IVC, and 596 patients (10.34%) had LRV variations. It was also shown that there was no difference between the prevalences of the variations in terms of gender difference. When associating anomalies were evaluated, it was seen that there was a significant increase in the risk of observing the horseshoe kidney anomaly in patients with retroaortic left renal vein (RALRV) variation. Conclusion: Vena cava variations are not rare. When present, they may coexist with other vena cava variations or other variations. These variations can easily be detected on CT. Properly characterizing and classifying IVC variations is crucial for proper planning of surgical interventions and transvenous interventions to prevent serious complications and failures.

The Retroaortic Left Renal Vein Abnormalities in Cross-Sectional Imaging

Abstract: Preoperative knowledge of LRV abnormalities facilitates the safe performance of surgery and reveals the clinical symptoms. It is easy to see LRV and its drainage way on routine CT and MR imagings.
