However, in patients with interrupted IVC, most of the blood from the lower body actually joins the blood from the upper body before returning to the heart via the superior vena cava (SVC).
Inferior vena cava syndrome (IVCS) is a very rare constellation of symptoms resulting from either obstruction or stenosis of the inferior vena cava.

In persistent left superior vena cava, the left brachiocephalic vein does not develop fully and the left upper limb and head and neck drain into the right atrium via the coronary sinus.
The pathway of fetal umbilical venous flow is umbilical vein left portal vein ductus venosus inferior vena cava eventually right atrium.. This anatomic course is important to recall when assessing the success of neonatal umbilical venous catheterization, as failure to cannulate through the ductus venosus results in malpositioned hepatic catheterization via the left or right portal veins.

The syndrome associated with PAPVR is more commonly known as Scimitar syndrome after the curvilinear pattern created on a chest radiograph by the pulmonary veins that drain to the inferior vena cava.
