Effort Thrombosis

Effort thrombosis is defined as a blood clot upper extremity veins that is caused by strenuous activity, or trauma. The blood clot restricts venous blood flow from the arm and can cause pain, weakness, and marked swelling.
Risk of effort thrombosis is increased with prolonged periods of inactivity, oral contraceptive use, blood clotting disorders, medications, strenuous repetitive overhead activities, and a history of thrombosis. This condition is treatable with anticoagulation (blood thinners). However, some residual symptoms may persist. Complications include persistent numbness or loss of arm strength, and chronic pain.

Symptoms include:

Treatment:

Initial treatment involves relative rest, application of heat, and elevation of the involved extremity. Medications to dissolve the clot (thrombolytics) or blood thinners (heparin, warfarin)  to prevent the clot from enlarging are often used. Non-steroidal anti-inflammatory medications or acetaminophen are often recommended as well. Surgery is rarely indicated.
