Quick Answer: What Is The Meaning Of Inferior Vena Cava?

What happens if the inferior vena cava is blocked?

There are serious side effects if the inferior vena cava (IVC) vein is blocked.

The most common cause of an IVC blockage is a blood clot or other complications from an IVC filter.

Some IVC blockages lead to paralysis and bowel obstruction..

Why is the inferior vena cava important?

Function. The inferior vena cava is a vein. It carries deoxygenated blood from the lower half of the body to the right atrium of the heart. The corresponding vein that carries deoxygenated blood from the upper half of the body is the superior vena cava.

What is the main function of inferior vena cava?

Structure and Function The inferior vena cava is ultimately responsible for the transport of almost all venous blood (deoxygenated) from the abdomen and lower extremities back to the right side of the heart for oxygenation.

Is the vena cava on the right or left?

In most cases, there is a normal right superior vena cava. However, in rare cases, the right superior vena cava is absent, and the left superior vena cava becomes the only systemic vein draining blood from the upper part of the body back to the heart.

What causes IVC thrombosis?

A significant cause of an IVC thrombosis is occlusion of an IVC filter which is becoming more prevalent due to the increased placement of these devices. Trauma is also a cause of inferior vena cava thrombosis. The injury can occur during percutaneous cannulation of the femoral vein or during cardiopulmonary bypass.

Does the inferior vena cava go through the liver?

Blood Supply of the Liver The hepatic veins carry blood to the inferior vena cava—the largest vein in the body—which then carries blood from the abdomen and lower parts of the body to the right side of the heart.

Does inferior vena cava have valves?

Many veins contain one-way valves to ensure the forward flow of blood back toward the heart. The IVC, however, does not contain such valves, and forward flow to the heart is driven by the differential pressure created by normal respiration.

How long does an IVC filter stay in place?

29-54 daysThe U.S. Food and Drug Administration (FDA) recommends removing temporary IVC filters after 29-54 days. While this is not very long, it should provide enough time for the acute threat to pass or to find another solution that can work on a long-term basis.

What is the largest artery in the body?

The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.

What is your inferior vena cava?

Responsible for carrying lower body blood back to the heart The inferior vena cava (also known as IVC or the posterior vena cava) is a large vein that carries blood from the torso and lower body to the right side of the heart.

How long is the inferior vena cava?

The average length from beginning of IVC to the lower renal vein was (10.6 ± 2.8) cm. The renal vein was located between the first and second lumbar vertebra, the IVC beginning was located between the fourth and fifth lumbar vertebra.

Can you live without an inferior vena cava?

A congenitally absent Inferior Vena Cava (IVC) is a rare anomaly that is recognised to be associated with idiopathic Deep Venous Thrombosis (DVT), particularly in the young. It may not be apparent until later in life.

Is IVC collapse normal?

The normal IVC diameter is less than 1.7 cm and there is a 50% decrease in the diameter when the RA pressure is normal (0–5 mm Hg). A dilated IVC (>1.7 cm) with normal inspiratory collapse (>50%) is suggestive of a mildly elevated RA pressure (6–10 mm Hg).

Where is the largest vein in your body?

Did you know that your Great Saphenous Vein is the longest vein in the human body? Extending from the top of your foot to the upper thigh and groin, THIS vein is the major culprit that causes Varicose Veins.

What does the name vena cava mean?

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.

What organ system does the inferior vena cava belong to?

cardiovascular systemfunction in cardiovascular system The inferior vena cava is a large, valveless, venous trunk that receives blood from the legs, the back, and the walls and contents of the abdomen and pelvis.

What causes enlarged inferior vena cava?

Inferior vena cava syndrome (IVCS) is a constellation of symptoms resulting from obstruction 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.

Where is the inferior vena cava located in the heart?

The inferior vena cava (IVC) is the largest vein of the human body. It is located at the posterior abdominal wall on the right side of the aorta. The IVC’s function is to carry the venous blood from the lower limbs and abdominopelvic region to the heart.
