Duplex ultrasound is a non-invasive form of imaging that can be used to examine both arteries and veins using sound waves at high frequency. It not only provides a two dimensional image of each blood vessel but can also be used to look at the direction and speed of blood flow. Most studies take 30 to 60 minutes.
This information can be used by Professor Varcoe to evaluate most vascular disorders, including
•Carotid occlusive disease
•Deep vein thrombosis
•Leg artery disease
•Arm artery disease
•Aorto-iliac occlusive disease
•Aneurysms in your abdomen or extremities
For most of these tests little preparation is required and you can go about your normal activities immediately afterward. Occasionally studies will require you to fast. It is best to ask about this when your appointment is made.
