“…15 In a study where no statistically signi cant correlation was found between gender and variations of the LRV and CLRV, RLRV was found to be statistically signi cantly higher in men than in women (p = 0.039). 19 In the present study, no di erence was found between genders in terms of IVC and LRV variations.…”

Objective: The aim of this study was to investigate percentages and gender distribution of the variations of the inferior vena cava (IVC), renal veins, and posterior lumbar tributaries of the left renal vein (LRV). Materials and Methods: For this cross sectional observational study, the computed tomography (CT) images of 1949 patients were evaluated retrospectively. Results: In the present study, percentages of double IVC, left IVC, and IVC interruption with azygos continuation were 0.5%, 0.2%, and 0.1%, respectively; circumaortic left renal vein (CLRV) was 6% and retroaortic left renal vein (RLRV) was 4.2%. Multiple renal vein variations were 24.1% on the right, but none on the left. Posterior lumbar tributaries of the renal veins were 0.15% on the right and 48% on the left. There was no difference between genders in terms of LRV and IVC variations. While the incidence of multiple right renal veins was statistically significantly higher in male patients compared to female patients (p = 0.045), the opposite was true for the posterior lumbar tributaries of the LRV (p = 0.035). Conclusion: The venous system has a wide variety of variations, and the renal venous circulation is supported by number variations on the right in men and collaterals on the left in women.

Lymphadenectomy has been an essential part of the surgical treatment in surgical oncology, as the lymphatic channels and nodes are the main dissemination pathway for most of the gynecological cancers. Pelvic and paraaortic lymphadenectomy are frequent surgical procedures in gynecologic oncology. Paraaortic lymph node dissection facilitates staging, prognosis, surgical and postoperative management of patients. It is one of the most challenging retroperitoneal surgeries. A comprehensive knowledge of the paraaortic region is mandatory. Intraoperative bleeding is the most common complication during lymphadenectomy due to direct vascular injury, poor tissue handling, exuberant retraction and possible anatomical variations of the vessels in the paraaortic region. Approximately, one-third of women will have at least one anatomic variation in the paraaortic region. It must be stressed that anomalous vessels may be encountered in every woman who will undergo surgery. Consequently, detailed knowledge of anatomical vessels variations is required in order to prevent iatrogenic vessel injury. The importance of these variations is well described in urology, vascular and general surgery. Conversely, in oncogynecological surgery, there are few articles, which described some of the vessels variations in the paraaortic region. The present article aims to propose a surgical classification and to describe the majority of vessels variation, which could be encountered during paraaortic lymphadenectomy in gynecologic oncology. Moreover, surgical considerations in order to prevent anomalous vessels injury are well described.

“…In ANCS, the LRV is compressed between the aorta and the superior mesenteric artery, whereas in PNCS, the LRV has a retroaortic course and is compressed between the aorta and vertebral column. Posterior NCS is the rarer of the two variants, with a prevalence of 0.77-1.56% (1,2).…”
