Inferior Vena Cava Duplication: Incidental Case in a Young Woman.

Coco D, Cecchini S, Leanza S, Viola M, Ricci S, Campagnacci R - Case Rep Radiol (2016)

Bottom Line: A case of a double inferior vena cava (IVC) with retroaortic left renal vein, azygos continuation of the IVC, and presence of the hepatic portion of the IVC drained into the right renal vein is reported and the embryologic, clinical, and radiological significance is discussed.The diagnosis is suggested by multidetector computed tomography (MDCT), which reveals the aberrant vascular structures.Awareness of different congenital anomalies of IVC is necessary for radiologists to avoid diagnostic pitfalls and they should be remembered because they can influence several surgical interventions and endovascular procedures.

Mentions: In fact in the same patient double IVC with a retroaortic left renal vein, azygos continuation of the IVC, and the presence of a hypoplastic hepatic segment of the IVC coexist the last one is drained into the right renal vein, at the confluence with right IVC, probably due to an incomplete atrophy of the right subcardinal vein (Figures 2 and 3). Therefore, with the partial atrophy of the prerenal division of the IVC, the blood returning from the lower extremities is partially shunted from the supracardinal system through the suprasubcardinal anastomosis to the retrocrural azygos vein, which is derived from the thoracic segment of the right supracardinal vein and partially shunted to the hepatic segment of the IVC through the residual prerenal segment.
