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.
