Ultrasounds are a non-invasive test, no needles are involved. Ultrasound imaging involves applying high frequency sound waves via a transducer to produce pictures of the inside of the body. Vascular ultrasound provides real time images of blood flowing through veins and arteries.

Vascular ultrasound is performed to:

  • Monitor blood flow to organs and tissues throughout the body
  • Locate and identify blockages (stenosis), plaque or emboli(clots)
  • Detect deep venous thrombosis (DVT)
  • Determine suitability for procedures such as angioplasty
  • Assess vein viability for use as a bypass graft
  • Evaluate success of bypass grafts of blood vessels
  • Determine the presence of arterial aneurysm (a bulge in the wall of an artery)
  • Determine the source and severity of varicose veins and spider veins
  • Monitor the progress of vascular problems such as an Abdominal Aortic Aneurysm
  • Provide ongoing surveillance of previous vascular surgery

Doppler ultrasound is used to see and evaluate:

  • Blockages to blood flow
  • Narrowing of blood vessels
  • Congenital vascular malformation
