What forms the inferior vena cava embryology?
The infrahepatic IVC develops from a set of 3 paired parallel veins appearing consecutively between 4 and 8 weeks of life, namely the posterior cardinal, subcardinal and supra cardinal veins (Figure 2). The suprahepatic IVC is derived from the cranial segment of the right vitelline vein.
How was the inferior vena cava formed?
The inferior vena cava (IVC) is a large retroperitoneal vessel formed by the confluence of the right and left common iliac veins. Anatomically this usually occurs at the L5 vertebral level.
What is duplicated inferior vena cava?
A double or duplicated inferior vena cava results from lack of atrophy in part of the left supracardinal vein, resulting in a duplicate structure to the left of the aorta. The common form is a partial paired inferior vena cava that connects the left common iliac and left renal veins.
What is the main function of the inferior vena cava?
The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
What are the tributaries of the inferior vena cava?
- I: common iliac veins.
- L: lumbar veins.
- T: right testicular (gonadal) vein.
- R: renal veins.
- S: suprarenal veins.
- H: hepatic veins.
What is double IVC?
Double inferior vena cava is a vein abnormality that is present from birth ( congenital ). Individuals with this anomaly have two inferior vena cavas instead of one. The inferior vena cava carries oxygen-poor blood from the lower parts of the body into the heart. Double inferior vena cava does not cause any symptoms.
Why is it called vena cava?
The venae cavae (/ˈviːni ˈkeɪvi/; from the Latin for “hollow veins”, singular “vena cava” /ˈviːnə ˈkeɪvə/) are two large veins (venous trunks) that return deoxygenated blood from the body into the heart. In humans there are the superior vena cava and the inferior vena cava, and both empty into the right atrium.
What are the branches of inferior vena cava?
