Vein mapping with ultrasound is a test which utilizes high frequency sound waves to obtain images of veins which are being evaluated for surgical removal or alteration. This test is used to determine if the veins are suitable for the desired surgical procedure. The technologist applies an acoustic gel on your arm or leg over the area to be viewed. Then a painless instrument called a transducer is gently moved across that portion of your body to visualize the inside of the vessels. The technician may mark on your arms to identify the location of your veins. These marks must not be removed until your doctor has directed you to do so.
During the test you will be asked to lie on your back (if possible), while a trained technician records the images made by the ultrasound. The test usually takes less than 90 minutes. Vein mapping does not hurt and there are no documented complications from the use of this type of ultrasound. During the test you may hear several strange noises coming from the machine. Do not become alarmed; these noises are actually the sound of blood moving through your body.
There are no special preparations for this test.
The technician will not discuss any findings or conclusions about the test with you. Your personal physician is responsible for providing you with this information.
