The superior vena cava (SVC) is a vital vein that carries deoxygenated blood from the head, neck, and upper extremities back to the heart. However, when this vein becomes blocked by an embolism or thrombosis, it can lead to serious complications and even death.
Acute embolism and thrombosis of the SVC are relatively rare but potentially life-threatening conditions that require prompt diagnosis and treatment.
In this blog post, we will discuss the causes, symptoms, and treatment options for acute embolism and thrombosis of the SVC, as well as the steps you can take to reduce your risk of developing these conditions.”
CAUSES
Acute embolism and thrombosis of the superior vena cava (SVC) can be caused by a variety of factors, including:
- The formation of blood clots in the veins,
- The presence of a foreign object in the blood vessels,
- Malignant tumor blocking the flow of blood in the SVC.
Other possible causes include trauma, inflammation, and a congenital abnormality of the blood vessels. In some cases, the exact cause of acute embolism and thrombosis of the SVC may not be able to be determined. It’s important to note that the superior vena cava is the vein that brings deoxygenated blood from the head, neck, and upper extremities back to the heart, so a blockage in this vein can cause serious symptoms and complications if not treated promptly.
THE UNDERLYING SYMPTOMS
- Difficulty breathing or shortness of breath
- Coughing up blood
- Headaches
- Fainting or loss of consciousness
- Feeling fatigued or weak
- High fever
- Rapid heart rate
- Chest pain

Risk factors include:
- A history of deep vein thrombosis (DVT) or pulmonary embolism (PE)
- Cancer and cancer treatments
- Surgeries or injuries that immobilize the body
- Pregnancy and postpartum period
- Obesity
- Smoking
- Use of hormonal therapy

DIAGNOSIS
The diagnosis of acute embolism and thrombosis of the superior vena cava (SVC) typically begins with a physical examination and a thorough medical history. Your healthcare provider may also perform several diagnostic tests to confirm the presence of a blood clot in the SVC and to determine the cause. Some common diagnostic tests include:
- Chest X-ray
- Computerized tomography (CT) scan
- Magnetic resonance imaging (MRI)
- Ultrasound
- Blood tests to check for clotting disorders or other underlying medical conditions
LINE OF TREATMENT
The treatment of acute embolism and thrombosis of the SVC typically involves a combination of anticoagulant medications, thrombolytic therapy, and interventional procedures. The goal of treatment is to prevent the clot from growing, to dissolve the clot and to remove it, and to prevent recurrence. Sometimes a surgery has also to be performed to remove the clot or to bypass the blocked vessel.
Patients who are on blood thinning medications such as WARFARIN[COUMADIN] are often asked to monitor their PT/INR LEVEL regularly. PATIENT SELF TESTING has made it convenient for people so they can easily monitor their PT/INR LEVEL with the help of PT/INR METERS at home and can get the reading in seconds.
