下腔静脉异常并不常见，大多数无症状。虽然罕见，但IVC异常可导致严重的出血并发症，特别是在髂动脉手术期间。这些变化的先验知识有助于正确解读放射学图像和安全执行介入手术和外科手术。在一具女性尸体的腹部常规解剖过程中，我们观察到了右侧重复下腔静脉的存在。两个IVC均位于腹主动脉右侧，一个位于腹侧，另一个位于背侧，分别命名为腹侧右IVC和背侧右IVC。腹侧和内侧放置的IVC（似乎是主要的IVC）由右髂总动脉前方的两条髂总静脉联合形成（主动脉前髂静脉汇合-“有袋腔”）。右髂外静脉继续作为更背侧和外侧放置的背侧右IVC。右髂内静脉在接受髂外横吻合静脉后继续作为右髂总静脉。这种横向吻合存在于右髂总动脉后面。较窄的背侧右IVC在肾静脉水平下方与较宽的腹侧右IVC相连，形成单个IVC。腹主动脉向左凸起。
Anomalies of the inferior vena cava (IVC) are uncommon and most of them remain asymptomatic. Though rare, anomalies of IVC can lead to severe hemorrhagic complications especially during aortoiliac surgery. Prior knowledge of these variations facilitates proper interpretation of radiological images and safe performance of interventional procedures and surgeries. During routine anatomical dissection of abdomen in a female cadaver we observed the presence of right sided duplication of IVC. Both IVCs were present on the right side of abdominal aorta, one ventral and the other more dorsal in position and named ventral right IVC and dorsal right IVC. The ventrally and medially placed IVC, which appeared to be the main IVC was formed by the union of two common iliac veins in front of the right common iliac artery (Preaortic iliac confluence-"Marsupial Cava"). The right external iliac vein continued as the more dorsally and laterally placed dorsal right IVC. The right internal iliac vein after receiving a transverse anastomotic vein from the external iliac continued as the right common iliac vein. This transverse anastomosis was present behind the right common iliac artery. The narrower dorsal right IVC joined the wider ventral right IVC just below the level of renal veins to form a single IVC. The abdominal aorta presented a convexity to the left.
