Effort Subclavian Vein Thrombosis
Effort subclavian vein thrombosis, also known as Paget-Schrotter 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.
Causes of Effort Vein Thrombosis
You may experience effort vein thrombosis if you have a large neck and upper-arm muscles or overexertion of those muscles. Other causes include:
- Presence of an extra rib above the first rib that compresses the subclavian vein
- Previous collarbone or rib fracture
- An abnormal ligament that compresses the subclavian vein
- Repetitive movement of the arm and shoulder with over the head extension
Symptoms of effort vein thrombosis include:
- Pain, swelling or congestion in the affected arm
- Affected arm turns blue
