What causes subclavian thrombosis?
Axillo-subclavian vein thrombosis (ASVT) occurs when blood clots form in your upper arm due to compression of certain veins. It’s usually the result of repetitive stress on your upper arms. Medication and surgery are the primary treatments for ASVT.
Is subclavian vein thrombosis serious?
Subclavian vein thrombosis (SCVT) is a condition where a blood clot forms in the subclavian vein. SCVT can occur from multiple etiologies and is a potentially life-threatening pathology if not treated in a timely manner. SCVT occurs due to either a primary etiology or a secondary etiology.
What happens if the subclavian vein is blocked?
A condition caused by repetitive arm motion This tissue causes the vein to narrow and restrict blood flow, leading to the formation of blood clots. Left untreated, axillo-subclavian vein thrombosis can cause: Arm pain and fatigue. Arm swelling.
What is DVT and PTE?
DVT: Deep venous thrombosis; PTE: Pulmonary thromboembolism.
What is effort thrombosis?
Effort subclavian vein thrombosis, also known as Paget-Schroetter syndrome, is a blood clot that occurs in the subclavian vein under the collarbone. A type of thoracic outlet syndrome, effort vein thrombosis usually occurs when the vein is compressed between the first rib and collarbone.
How do you treat subclavian vein thrombosis?
Initial treatment of subclavian vein thrombosis consists of conservative management, which includes rest, elevation of the limb, and application of heat or warm compresses. In a few patients who have minimal symptoms and no anatomic defects, physical therapy is the first component of treatment.
What is the difference between DVT and thrombosis?
A blood clot in a deep vein of the leg, pelvis, and sometimes arm, is called deep vein thrombosis (DVT). This type of blood clot does not cause heart attack or stroke. A blood clot in an artery, usually in the heart or brain, is called arterial thrombosis.
What is the subclavian vein?
The subclavian vein (SVC) is classified as a deep vein and is the major venous channel that drains the upper extremities. Other deep veins of the upper extremity that accompany the major arteries include the radial, ulnar, brachial, axillary veins.
Is thrombosis the same as a blood clot?
Thrombosis occurs when a thrombus, or blood clot, develops in a blood vessel and reduces the flow of blood through the vessel. Embolism occurs when a piece of a blood clot, foreign object, or other bodily substance becomes stuck in a blood vessel and largely obstructs the flow of blood.
Is thrombosis a blood clot?
Key points. Thrombosis occurs when blood clots block veins or arteries. Symptoms include pain and swelling in one leg, chest pain, or numbness on one side of the body. Complications of thrombosis can be life-threatening, such as a stroke or heart attack.

Effort subclavian vein thrombosis, also known as Paget-Schroetter syndrome, is a blood clot that occurs in the subclavian vein under the collarbone. A type of thoracic outlet syndrome, effort vein thrombosis usually occurs when the vein is compressed between the first rib and collarbone.
What is effort vein thrombosis?
A type of thoracic outlet syndrome, effort vein thrombosis usually occurs when the vein is compressed between the first rib and collarbone. You may experience effort vein thrombosis if you have a large neck and upper-arm muscles or overexertion of those muscles.
What are the differential diagnoses of subclavian vein thrombosis?
Differential diagnoses of subclavian vein thrombosis include: Superior vena cava syndrome Lymphatic obstruction Cellulitis Thoracic outlet obstruction
What happens to the subclavian vein when abducted?
When the arm abducts, the subclavian vein is compressed between the clavicle and the first rib. This results in the perfect setup for Virchow’s triad- endothelial cell damage, inflammation, scarring, hypercoagulability, and stasis of blood.
