Figure 1. Precardinal/anterior cardinal vein developmental process (image taken from Phlebolymphology. Vol. 19, No. 4, 2012).
Figure 2. The white arrow demonstrates the tip of the CVC apparently in the left subclavian vein.
Figure 3. Ultrasonographic imaging demonstrating the metallic guide of the CVC (white arrow) in a dilated coronary sinus (*).
Figure 4. The black arrow demonstrates the tip of the CVC, apparently in the PLS-SVC.
Figure 5. (a) Injection of contrast medium directly from the CVC into the dilated CS. (b) Early opacization of the pulmonary artery demonstrates that the PLS-SVC drains into the right atrium.
Figure 6. On the left: CT axial view of the PLS-SVC and the right brachiocephalic vein crossing the midline. On the right: the dilated coronary sinus.
Figure 7. The white arrow indicates a hypertrophic hemiazygos vein (6) which drains directly into the PLS-SVC just like a normal azygos vein would do on the right side.
