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.
How long can you live with superior vena cava syndrome?
The average life expectancy for patients who present with malignancy-related SVC syndrome is 6 months, although the prognosis is quite variable depending on the type of malignancy.
What are the signs and symptoms of superior vena cava syndrome?
The most common presenting symptoms of SVC syndrome are face/neck swelling, distended neck veins, cough, dyspnea, orthopnea, upper extremity swelling, distended chest vein collaterals, and conjunctival suffusion.
How would damage to the superior vena cava affect the body?
SVCS is serious when it occurs in adults. But it can be life-threatening in children. Symptoms include trouble breathing, coughing, and swelling of the face, neck, upper body, and arms. Treatment options for SVCS caused by cancer may include radiation therapy, chemotherapy, thrombolysis, and stent placement.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.
What is the main cause of the superior vena cava syndrome?
Superior vena cava syndrome (SVCS) happens when the superior vena cava is partially blocked or compressed. Cancer is usually the main cause of SVCS.
Can you live without an IVC?
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 does SVC syndrome feel like?
Dyspnea is the most common symptom, observed in 63% of patients with SVCS. Other symptoms include facial swelling, head fullness, cough, arm swelling, chest pain, dysphagia, orthopnea, distorted vision, hoarseness, stridor, headache, nasal stuffiness, nausea, pleural effusions, and light-headedness.What side is your vena cava on?
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.
What is the most common physical finding in patients with superior vena cava syndrome?Dyspnea is the most common symptom, observed in 63% of patients with SVCS. Other symptoms include facial swelling, head fullness, cough, arm swelling, chest pain, dysphagia, orthopnea, distorted vision, hoarseness, stridor, headache, nasal stuffiness, nausea, pleural effusions, and light-headedness.
Article first time published onCan you live without a superior vena cava?
Complete absence of both SVC is very rare and usually accompanied by other congenital anomalies of the heart, including cardiac conduction system, or thoracic duct system.
What is the treatment for superior vena cava syndrome?
The main treatment for SVCS is to treat the cancer that is causing it with chemotherapy or radiotherapy. However, other things can be done to alleviate the symptoms. Your doctor might prescribe corticosteroids to reduce swelling or diuretics to remove excess fluid from your body by increasing urination.
Where is superior vena cava located?
The superior vena cava is located in the thorax (chest), more specifically, it is in the anterior (front) right, superior (above) mediastinum. The superior vena cava starts at the lower border of the first costal cartilage.
What is vena cava from upper body?
(VEE-nuh KAY-vuh) A large vein that carries blood to the heart from other areas of the body. 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.
Does portal vein thrombosis cause pain?
Portal vein thrombosis causes upper abdominal pain, possibly accompanied by nausea and an enlarged liver and/or spleen; the abdomen may be filled with fluid (ascites). A persistent fever may result from the generalized inflammation.
How can you tell the difference between SVC and IVC obstruction?
In patients with dilated abdominal wall veins due to cirrhosis, the direction of blood flow is away from the umbilicus (radiating like a star from the umbilicus), whereas in vena caval obstruction, the direction of blood flow is either completely above downward (superior venacaval obstruction) or completely below …
Where is IVC thrombus?
Additionally, the thrombotic findings are dependent on the degree of occlusion of the IVC and on the location between the iliac confluence and the right atrium. Patients who have IVCT may present only after having pulmonary embolism (PE).
What are some of the side effects of an IVC filter?
- Infection.
- Excess bleeding.
- Allergic reaction.
- Damage to the blood vessel at the insertion site.
- Blockage of blood flow through the vena cava, which can cause leg swelling.
- A filter that travels to the heart or lungs, causing injury or death.
Is IVC filter placement a major surgery?
About the Procedure IVC Filter placement and removal is a minimally invasive surgery. The implantation of the IVC filter involves a local anesthetic and numbing medication injected in your skin in the area that the IVC filter will be inserted, preventing discomfort during the surgery.
Can IVC filter cause back pain?
Abdominal or back pain associated with an IVC filter is typically due to penetration through the blood vessel wall, impingement against nearby nerves, and/or penetration into adjacent organs. Migration of filter components or referred pain may affect other areas of the body.
Why does superior vena cava cause dyspnea?
Initially, there are few symptoms, however, over time, symptoms of superior vena cava gradually develop. As the compression becomes more severe, the patient may develop shortness of breath and swelling of the arms and face. The symptoms occur because blood cannot return to the heart.
How common is SVC obstruction?
It occurs in approximately 15,000 persons in the United States each year (1). SVC syndrome is the clinical manifestation of SVC obstruction and occurs through external compression, thrombosis or invasion of the vein. SVC syndrome is now almost exclusively (more than 90%) secondary to malignancy.
What drains into the superior vena cava?

What type of blood does the vena cava carry?
The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.
Where is vena cava in back?
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. Unlike the superior vena cava,…
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 does the inferior vena cava do for the heart?
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.
What could be the effect of the superior and inferior vena cava were blocked by cholesterol?
Overview. Superior vena cava syndrome is caused by the partial blockage of the superior vena cava, which is the vein that carries blood from the head, neck, chest, and arms to the heart. Symptoms that may indicate this syndrome include difficulty breathing, coughing, and swelling of the face, neck, upper body, and arms …
How many superior vena cava are there?
The superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart. It is a large-diameter (24 mm) short length vein that receives venous return from the upper half of the body, above the diaphragm.
How do you manage SVC obstruction?
The principal options for endovascular therapy today are stenting, percutaneous transluminal angioplasty (PTA), thrombolysis, or some combination thereof. In most patients with SVCS, stenting of the SVC provides rapid symptomatic relief within few days (see the images below).
