Carotid Artery

The carotid artery ultrasound scan is most frequently performed to detect narrowing, or stenosis of the carotid artery, a condition that substantially increases the risk of stroke. It is used as a general screening tool for patients over 45 years or if you have history of cardiovascular disease or at risk of stroke.

The scan will evaluate the size, shape, and outline, measuring also the blood flow velocities in the:

• Common carotid arteries from their origin to bifurcation including intimal thickness
• Internal and external carotid arteries
• Vertebral arteries

Common pathology which can appear on the scan are plaque deposits and subsequent narrowing of the arteries particularly the internal carotid artery which supplies blood to the brain.

Deep Vein Thrombosis (DVT)

If you are suffering from pain, swelling and tenderness in one or both of your legs (usually your calf) or a heavy ache, warm skin or redness, particularly at the back of your leg, it may be a sign of a deep vein thrombosis (DVT).

The main danger is that the clot may break up and travel up to the lungs blocking blood flow and oxygenation. This can be life-threatening. An ultrasound scan of the legs may be needed.
