Score: 4.6/5 (35 votes)
The vena cava has two parts: the superior vena cava and 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.
Is inferior vena cava anterior?
The anterior vena cava, also known as the precava, drains the head end of the body, while the posterior vena cava, or postcava, drains the tail, or rear, end. In humans these veins are respectively called the superior and inferior venae cavae.
What level is inferior vena cava?
The inferior vena cava begins as the left and right common iliac veins behind the abdomen unite, at about the level of L5. It passes through the thoracic diaphragm at the caval opening at the level of T8 - T9. It passes to the right of the descending aorta.
What forms the inferior vena cava?
In vena cava: Inferior vena cava. The inferior vena cava is formed by the coming together of the two major veins from the legs, the common iliac veins, at the level of the fifth lumbar vertebra, just below the small of the back.
Can you live without an inferior vena cava?
Absence of the inferior vena cava is a rare vascular anomaly, which usually remains asymptomatic in childhood. It is recognized as the risk factor for deep venous thrombosis, since the collateral circulation does not provide adequate drainage of the lower limbs.
What happens if the inferior vena cava is blocked?
A blockage in the inferior vena cava (IVC) can lead to chronic leg swelling, pain, and immobility, according to the University of California Los Angeles (UCLA) IVC Filter Clinic. There may be other health complications depending on a person's age and preexisting medical conditions.
What causes enlarged inferior vena cava?
The IVC diameter is affected by right heart function, as well as conditions like IVC aneurysm or Budd-Chiari syndrome (BCS), which directly or indirectly increase the volume of the blood in the right heart or increase the back pressure on the systemic circulation ultimately leading to IVC dilation [2,3].
Why is the inferior vena cava important?
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 is the largest vein in the 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.
Is the vena cava an artery?
Large red vessel (the aorta) - Large artery that carries blood from of the left ventricle to the arteries of the body. Large blue vessel (vena cava) _(includes the superior and inferior vena cava) - _Large vein that empties blood into the right atrium of the heart.
What does IVC filter stand for?
An inferior vena cava (IVC) filter is a small device that can stop blood clots from going up into the lungs. The inferior vena cava is a large vein in the middle of your body.
What does a dilated inferior vena cava mean?
Inferior vena cava (IVC) is a large collapsible vein whose diameter and extent of inspiratory collapse are known to correlate with right atrial (RA) pressures; hence, IVC dilatation represents a cardiac pathology. IVC dilatation in the absence of any cardiac involvement is termed as idiopathic.
Why are there no valves in the vena cava?
What makes the IVC different from other veins is that there are no valves within the vein to keep blood moving forward instead of backward, which is how the typical anatomy of a vein works. To prevent the blood from moving back into the body, valves made up of tissue in the vein close as the blood through it.
Where are the largest arteries?
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 inferior vena cava syndrome?
Inferior vena cava syndrome (IVCS) is a sequence of signs and symptoms that refers to obstruction or compression of the inferior vena cava (IVC). The pathophysiology of IVCS is similar to superior vena cava syndrome (SVCS) because of the presence of an underlying process that inhibits venous return to the right atrium.
What are the symptoms of inferior vena cava syndrome?
The syndrome of intrahepatic inferior vena cava obstruction has neither been commonly recognized nor adequately described. Symptoms include the abrupt onset of ascites, hepatomegaly, and fluid retention below the diaphragm with edema of the lower extremity. Proteinuria can be associated with these symptoms.
How is inferior vena cava syndrome treated?
The treatment of vena cava compression syndromes commonly involves stenting or radiation. Expandable metallic stents have been used to treat IVC compression caused by hepatic tumors . Tumors that compress the SVC, such as lung cancer, are generally radiosensitive .
What causes blood clots in the inferior vena cava?
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.
What type of doctor removes an IVC filter?
This removal may be performed when the risk of clot travelling to the lung has passed. This should be assessed by a physician or the interventional radiologist who inserted the IVC filter sometime after placement, ideally less than six months after insertion.
How long can you keep an IVC filter?
The 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 happens when an IVC filter catches a clot?
When an IVC filter has captured a blood clot traveling through the inferior vena cava vein, the filter clogs and creates a host of medical symptoms, including: Swollen legs, Leg pain, and. The feeling of internal pressure in the legs.
Should I have my IVC filter removed?
When should an IVC filter be removed? It is recommended that a removable filter be removed when the risk of a blood clot traveling to the lungs has passed, or if a patient can take blood thinners.
What are the side effects of the IVC filter?
- Access site bleeding.
- Migration to the heart or lungs.
- Failure to open.
- Filter fracture.
- Vein perforation.
- Blockage of blood flow causing clots.
