“…A study, the RLRV rate was 6.9%, which is quite high when compared with those of other studies [1,3,4,12,15]. As in many other studies, no significant correlation was found between LRV variations and gender in our study [5,7,15].…”

“…Similar to our results, Saldarriaga et al [13] did not observe gender differences in frequency of supernumerary arteries. Frequency of circumaortic left renal vein in our population was 4.72%, which fits its reported range from 2% to 17% [18]. Bilateral supernumerary renal arteries were found in 11.4% of our patients, which is similar to the frequency of 6-15% reported in the literature [15,16,19].…”
“…Circumaortic vein results if there is persistence of the dorsal collar ( Figure 13). The incidence of this anomaly is 1.5% to 16% (34)(35)(36). Care should be taken to avoid misdiagnosis of this condition as retroperitoneal adenopathy (27).…”
With the increased use of cross-sectional imaging, systemic venous anomalies are more frequently being recognized in asymptomatic patients. Accurate characterization of systemic venous anomalies plays a major role in the appropriate selection of a surgical approach or interventional procedure.In this article, we review common and uncommon inferior vena cava (IVC) anomalies. We describe the embryological basis and clinical implications of these anomalies, particularly from an interventional radiology perspective. We also discuss the complications and treatments of these anomalies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
