How is axillo-subclavian vein thrombosis diagnosed?
Your doctor will likely use a series of imaging studies to locate the blood clot in your vein. You will not need all of these tests, but you may have more than one. These studies include:
- Duplex ultrasound
- Catheter-directed contrast venography
- CTA (computerized tomography arteriography)
- MRA (magnetic resonance arteriography)
In addition, a vascular specialist may order blood tests to see if a genetic condition is responsible for the axillo-subclavian vein thrombosis. Some genetic conditions that make the blood more prone to clotting (hypercoagulable syndromes), including factor V Leiden mutation, Lupus anti-coagulant, and others can lead to axillo-subclavian vein thrombosis. Your doctor will order blood tests to measure the amount of time it takes for your blood to clot.
