Learning objectives

To review the anatomy of the paraumbilical veins. To discuss the pathologies in which they can become enlarged. To highlight associated ultrasound findings that help establish the correct diagnosis.

Background

THE UMBILICAL VEIN In adults, the umbilical vein is usually completely occluded, mainly in its distal part, forming the round ligament, a fibrous structure. A very thin patent remnant of the umbilical vein may be present in connection with the left branch of the portal vein in normal individuals. It is called the Baumgarten’s recess [1]. THE PARAUMBILICAL VEINS The paraumbilical veins are found around the falciform ligament next to the round ligament. They are composed by Burow's veins and Sappey's inferior and superior veins...

Findings and procedure details

As previously explained, the paraumbilical veins can become dilated and allow blood flow away from the liver (hepatofugal direction) or towards the liver (hepatopetal). The first being related to PORTAL HYPERTENSION and the second to CHRONIC EXTENSIVE INFERIOR VENA CAVA THROMBOSIS. We present a series of cases of patent paraumbilical veins found on ultrasound examination divided by mechanism of occurrence and etiology. PORTAL HYPERTENSION In this scenario, the increase of the blood pressure inside the portal system, notably in the left branch of the portal...

Conclusion

A patent paraumbilical vein during ultrasound examination points towards portal hypertension or IVC thrombosis. Studying the direction of the blood flow and seeking associated findings is mandatory for establishing the correct diagnosis.
