“…Inferior vena cava (IVC) and renal vein variations originate from the anomalies in the anastomoses of the three paired veins, including subcardinal, supracardinal and postcardinal veins, during embryonic development, and they may have numerous forms (1,2). Normally, a single left renal vein (LRV) drains into the IVC by crossing anteriorly over the abdominal aorta in the majority of cases.…”

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.

“…These anomalies may pose technical challenges for advancing temporary pacing wires, Swan Ganz catheters, performing right heart catheterization or placement of IVC filters. 8 The left-sided IVC may also be associated with anomalies of the renal veins, therefore surgery performed in the retroperitoneum may entail risk to vascular structures if IVC anomalies are not suspected. 9 …”

Successful radio-frequency catheter ablation of two cases of supraventricular tachycardia via a left-sided inferior vena cava

Congenital venous anomalies are uncommon, incidental findings encountered during adult interventional electrophysiology procedures. Femoral venous access is conventionally used during cardiac electrophysiology studies to gain access to the heart. The chance finding of an inferior vena cava anomaly may preclude the performance of these procedures from the femoral approach. We describe two cases in which we were able to successfully perform different radiofrequency catheter ablation procedures in the presence of an unusual venous anomaly, the left-sided IVC. doi: https://doi.org/10.12669/pjms.36.6.2947 How to cite this:Awan RA, Khanzada MF, Mumtaz Z, Qadir F.

“…In mammals, the caudal vena cava receives blood from the caudal trunk, abdomen, pelvis, and caudal limbs, and delivers it to the right atrium of the heart. The caudal vena cava arises from three pairs of symmetrical veins but the right vein only remains through a complex process including development, regression and anastomosis [4, 5]. Firstly, the postcardinal veins appear and drain the caudal trunk.…”

Slc:Hartley guinea pigs frequently possess duplication of the caudal vena cava

et al. 2019

The formation of the caudal vena cava is a complex process involving development, regression, and anastomosis. In mammals, the normal caudal vena cava runs to the right side of the abdominal aorta, while duplication of the caudal vena cava has been identified as a congenital abnormality in both companion animals and humans. The present study demonstrates that Slc:Hartley guinea pigs frequently possess asymptomatic duplicated caudal vena cava. The prevalence was 30% and 24% for males and females, respectively, with no sex-related differences. In accordance with Saad et al. (2012)’s criteria, duplicated caudal vena cava were classified into two distinct variations. The dominant variation was a complete duplication without iliac anastomosis where the left caudal vena cava continued from the left common iliac vein and joined the left renal vein; the left renal vein ran to the right to join the right caudal vena cava. The alternative variation was an incomplete duplication where the left caudal vena cava joined the right infrarenal caudal vena cava at a more cranial point than in normal cases; the renal segment was unchanged. Iliac anastomosis was not found in any cases. Duplicated caudal vena cava neither affected the body weight nor the kidney weight. In conclusion, Slc:Hartley guinea pigs frequently possess asymptomatic duplicated caudal vena cava in the absence of iliac anastomosis and appear to be a novel and useful animal model for duplicated caudal vena cava in animals and humans.
