The document describes the typical course of an umbilical venous catheter (UVC) as it is inserted, including how it normally coils in the liver within the capacious space where the umbilical vein and left portal vein join. It notes that deviations can occur, with the UVC sometimes deviating to the right at the level of the right portal vein or to the left at the level of the left hepatic vein. Rarely, the catheter can pass through a patent foramen ovale into the left atrium, left ventricle, or pulmonary vein if inserted too far.

7. UVC is coiled in the liver, make a correct turn around and exit via the ductus
venous. coil is within the capacious space where the umbilical vein and left
portal vein join .

8. The UVC deviates to the right at the level of the right portal
vein. Air in portal venous branches associated with umbilical
venous catheter insertion.

9. The UVC has deviated medially at the level of the left portal vein. It
may also have looped in the capacious space at the junction of the
umbilical vein and left portal vein.

10. The UVC has deviated to the left at T8 which is the level of the left hepatic
vein. The UVC tip is most likely to lie within the left hepatic vein.

11. The level and angle of the catheter suggests that it is in the portal
vein with the tip possibly in the SMV.

12. UVC in jugular vein.

13. UVC into jugular vein.

14. UVC tip in right atrium.

15. Tip of an umbilical venous catheter (straight arrow) in the left
atrium; it has passed through a patent foramen ovale.

16. The UVC tip is in the pulmonary vein.

17. The UVC is in too far, passing through the foramen ovale and
into left atrium then left ventricle.
