Vascular Doppler is an ultrasonic diagnostic test which measures the direction and velocity of blood flow as they move through vessels. It helps to assess blood flow obstructions such as clots, and narrowing of the vessels caused by obstructive arteriosclerosis.
It is can be used to assess:
- Carotid arteries.
- Arteries and veins of the extremities.
When is it recommended?
It is indicated in patients with cerebral vascular disease (eg stroke) or suspected peripheral vascular disease (eg. Varicose veins, limb ischemia).
What preparation is required?
No previous preparation is needed.
How is the procedure performed?
It is performed with the patient lying on an examination couch. The doctor applies a gel on the surface of the skin to explore the selected area. This is a painful test with no side effects.
