Why is this procedure done?
A venous duplex ultrasound looks at how blood is flowing through your blood vessels. It uses sound waves to make images or pictures. With this kind of test, the doctor is looking at the blood vessels of your arms, legs, neck, or belly. It is done to: ‚
- See if something is blocking the blood vessel
- Look for a cause of pain, swelling, and other arm or leg problems
- Detect blood clots or tumors
- Look for poor vein function
- Help find out the exact place where needles or catheters will go
- Help find the vein that will be used for other surgical procedures
What will the results be?
A special doctor will look at the ultrasound. The results will help your doctor understand if there is a problem with your blood vessels. Together you can make a plan for more care. ‚
What happens before the procedure?
