Inferior vena cava syndrome (IVCS) is a very rare constellation of symptoms resulting from either obstruction or stenosis of the inferior vena cava. It can be caused by physical invasion or compression by a pathological process, or by thrombosis within the vein itself. It can also occur during pregnancy. Symptoms including high venous pressure ...
Aortocaval compression syndrome, also known as supine hypotensive syndrome, is compression of the abdominal aorta and inferior vena cava by the gravid uterus when a pregnant woman lies on her back, i.e. in the supine position.
Oxygenated blood from the placenta is carried to the fetus by the umbilical vein, which will drain into the inferior vena cava (IVC) through the ductus venosus or the liver. [5] When oxygenated blood enters the IVC, it moves in parallel with deoxygenated blood from the fetal systemic veins, establishing a bilaminar blood flow as it enters the ...
There is also increased blood stasis due to the compression of the vena cava by the enlargening uterus. [28] Many factors have been shown to increase the risk of clots in pregnancy, including baseline thrombophilia, cesarean section, preeclampsia, etc. [25] Clots usually develop in the left leg or the left iliac/ femoral venous system.

Pregnancy is the time during which one or ... Can be caused by inferior vena cava syndrome resulting from compression of the inferior vena cava and pelvic veins by ...
This commonly occurs in the upper and lower extremities. Compression of the inferior vena cava (IVC) [23] and pelvic veins by the uterus leads to increased hydrostatic pressure in the vasculature of the lower extremities. This increase in pressure shunts fluid from within the vasculature to the extracellular space.
My surgeons then stopped the surgery and took me to radiology where they placed a small metal device called an Inferior Vena Cava (IVC) filter to prevent further blood clots. I was sedated for 24 ...
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.
