What to Expect

Once in the room, you will be asked to remove your pants, shoes and socks and change into a gown. Once changed, you will lie down on the exam table. The technologist will apply warm to your leg. The technologist will use a transducer to send the ultrasound waves into your body. The ultrasound waves will produce a picture of your veins on the ultrasound machine and the technologist to assess the vein for blood clots. A slight pressure will be applied in many segments of your leg in looking for blood clots. The technologist will take several pictures from several different areas of your leg, with and without pressure. The exam will take 30 minutes for one leg and 60 minutes for both. After the exam is completed, our vascular specialist will review the information and the results will be discussed with you at your follow up appointment.
