Inferior vena cava blockage

The Inferior Vena Cava: An Overview

Understanding the function of the inferior vena cava and why blockages and blood clots are harmful may be beneficial. The inferior vena cava and superior vena cava (also known as venae cavae) are major veins found in the human body. The superior vena cava is a vein in the upper chest that transports deoxygenated blood from the upper torso, neck, face, and arms to the right atrium of the heart.

The inferior vena cava is located in the rear of the body, parallel to the spine. It transports deoxygenated blood to the heart from the legs, back, abdomen, and pelvis. People with Deep Vein Thrombosis (DVT), or those who have blood clots in a deep leg vein, are at risk for IVC blockage.

A blood clot breaking off and moving to the heart, lungs, or brain is also more likely if you have DVT. Patients may get a heart attack, pulmonary embolism, or stroke if this occurs.

High venous pressure in the lower limbs, decreased blood return to the heart, decreased cardiac output due to occlusion of the inferior vena cava, a sudden spike in venous pressure that can lead to placental separation, and a reduction in kidney function are all symptoms of pregnancy. All of these problems can result from resting in the supine posture late in pregnancy, which can cause the uterus to compress the inferior vena cava. Intense pain in the right side, muscular twitching, hypotension, and fluid retention are all symptoms of late pregnancy inferior vena cava syndrome.

When the Inferior Vena Cava is blocked, what happens?

According to the University of California Los Angeles (UCLA) IVC Filter Clinic, a blockage in the inferior vena cava (IVC) can cause chronic limb swelling, pain, and immobility.

Other health issues may arise as a result ofIf the inferior vena cava (IVC) vein is obstructed, it might have catastrophic consequences.

A blood clot or other problems from an IVC filter are the most common causes of an IVC obstruction. Some IVC obstructions result in intestinal obstruction and paralysis. a person’s age and pre-existing medical disorders.

Symptoms and signs

IVCS manifests itself in a wide range of signs and symptoms, making clinical diagnosis difficult.

  • A rise in venous blood pressure causes edema in the lower extremities (peripheral edema).
  • This is due to a drop in preload and cardiac output, which leads to an increase in frequency.
  • Cardiotocography can detect indicators of fetal hypoxia and distress in pregnant mothers. This is caused by reduced uterine perfusion, resulting in fetal hypoxemia.
  • Hypotensive syndrome in the supine position


  • Deep vein thrombosis or tumors can obstruct the flow of blood (most commonly renal cell carcinoma)
  • External pressure from nearby structures or tumors compresses the vein, either considerably compressing it or inducing thrombosis by creating turbulence and disrupting blood flow. When the uterus compresses the vein in the right side position during the third trimester of pregnancy, this is extremely typical.
  • Iatrogenic causes may be suspected in patients with a medical history of liver transplantion, vascular catheters, dialysis and other invasive procedures in the vicinity
  • Budd-Chiari syndrome

The Most Common Cause of Inferior Vena Cava Blockage Is IVC Filters

When lying on their backs, some pregnant women have problems with the IVC. The fetus’s weight can press against the vein, causing complications during pregnancy and delivery. To ensure normal blood flow from the IVC, pregnant women are recommended to sleep on their left side.

According to the website, the most common cause of blood clots or blockages in the IVC is the implantation of an IVC filter. Because of potentially deadly side effects and complications, the FDA has issued a warning for these filters.


Clinically, the diagnosis can be made by viewing the patient in the right-sided posture, when many dilated veins over the belly due to collaterals can be seen.  The IVC and circulatory system can be assessed using ultrasound with Doppler flow measurement.


The reason of vena cava compression or stoppage will determine the treatment. Positional adjustments and avoidance of supine lying, particularly on the right side, are frequently used in treatment. The definitive care of the IVCS during pregnancy is to deliver the baby. Symptoms will be relieved in other cases by medical or surgical therapy to remove or alleviate the problematic structure.

Blockages Are One of Many Potential Side Effects of an IVC Filter

A small metal device called an IVC filter is put into the inferior vena cava to prevent blood clots from going to the lungs, heart, and brain. IVC filters have the appearance of little metal cages or umbrellas.

They were created for those who are unable to take blood thinners, which are the conventional treatment for DVT and pulmonary embolisms (PE).

The Food and Drug Administration (FDA) in the United States, however, issued a warning in 2010 advising clinicians to avoid utilizing these potentially lethal medical devices. In addition to the risk of a blood clot blocking the IVC, IVC filters have the following negative effects:

  • Device breaking inside the body
  • Device migrating (moving)
  • Improper placement
  • Organs with perforations
  • Internal hemorrhage
  • Heart beats that are abnormal
  • Hypotension
  • Embolisms of the lungs
  • Problems with retrieving the device
  • Pain
  • Death

Although doctors are advised against implanting IVC filters in patients, they may do so in exceptional cases. These circumstances include the following:

  • Patients who are unable to tolerate anticoagulant medication due to DVT or PE (blood thinners)
  • When blood thinners are ineffective in the treatment of DVT or PE,
  • After a major pulmonary embolism has occurred and traditional methods have failed, emergency therapy is required.

What Happens if the Inferior Vena Cava of You or a Loved One Is Blocked?

The following are some of the symptoms and indicators of an IVC blockage:

  • Swelling in the legs, abdomen, or genital area that is visible (sometimes all three areas appear swollen)
  • Lower-extremity aches and pains
  • Walking difficulties or immobility

If you or someone in your family has an IVC filter and is experiencing these or other strange symptoms, seek medical help immediately once. When it comes to potential heart or circulatory system difficulties, you should not take any chances.

If you have a blocked IVC, a medical specialist can identify your symptoms and recommend treatment. An IVC blood clot filter lawsuit lawyer can help you recover compensation if your condition was caused by an IVC filter.

Potential Compensation for IVC Blockage or Other Complications

You may be entitled to compensation if you or a family member had an IVC blockage or other issues as a result of an IVC filter. Tosi & Rose is a law firm that represents wounded and disabled people in mass tort product liability cases.

If you meet the criteria, you may be able to receive compensation for physical, emotional, and financial losses such as:

    • Hospitalization
    • The IVC issue is treated with surgery.
    • Additional medical costs

  • Pay cut
  • Suffering and pain
  • Disability
