What happens during a venous ultrasound exam?

A consent form tells you what you are agreeing to, but it may not describe the room. For a venous ultrasound, one named source describes the first steps plainly.

What the source says happens first

You lie down and gel goes on your skin. The page at my.clevelandclinic.org on upper or lower venous extremity ultrasound says: "You will lie on a padded examining table. A warm, water-soluble gel is applied to the skin over the area to be examined. The gel does not harm your skin or stain your clothes."

Three sentences, three limits

The first sentence names the table and the position, and nothing else. It does not say how long you stay or whether you ever stand. The second sentence refers to "the area to be examined" without saying which area that is for you. The third covers skin and clothes. It does not cover anything else.

All three stop before the scan itself. There is no duration and no description of what the person holding the probe does. For background on the conditions that bring people to this exam, see these pages on deep vein thrombosis and on varicose veins and how they are evaluated.

What to ask before you book

Which leg or area will be scanned? How long should the appointment take? Is a change of clothing needed, and will the position change during the scan?

Ask them when you call a clinic in Oak Lawn, and write each answer on the same page as your order.

The desk's note

The paperwork describes the start of the exam. The rest happens in the room, and only the person doing it can describe it.
