Learning objectives

To define and to identify the spectrum of variants of the inferior vena cava and interpret them properly to avoid diagnostic errors.

Background

The inferior vena cava is the main venous return duct from the lower extremities and abdominal viscera to the right atrium. It is associated with a wide spectrum of congenital anatomical variants, as well as their main branches. Most of these variants are asymptomatic and diagnosed incidentally. To understand the different anatomical variants, we must rely on the embryology of the inferior vena cava, since it reflects an abnormal regression, persistence or anastomosis of the veins of the embryo. Among the anomalies of the inferior...

Findings and procedure details

EMBRIOLOGIC DEVELOPMENT It is important to know the embryogenesis of the inferior vena cava, because the different anatomical variants have their origin in anomalies in the process of regression, persistence or anastomosis of the embryonic veins. The embryo has three pairs of veins, which are located on both sides of the Aorta. The left veins and the communicating veins involve, and it is from the anastomosis of the following embryonic veins that the inferior vena cava is formed. -Posterior cardinal vein: it is the first...

Conclusion

Radiologists should be familiar and be able to recognize congenital anomalies of the inferior vena cava. These anomalies should be mentioned in the radiological reports because they can have significant clinical implications in the management of patients.
