If you are scheduled as an outpatient, you will be asked to report to the Heart and Lung Center at Portsmouth Regional Hospital.

You will be asked to report15 minutes before your examination in order to register.

If you are scheduled as an inpatient, your test will be performed in the Short Stay Unit before surgery, or in your room in the hospital.

A qualified technologist will perform the procedure.

You will be asked to lie down on a bed or stretcher.

The technologist will utilize an ultrasound probe covered with gel to obtain the necessary images. The technologist will move the probe all over the extremity (ies) your physician requests. That may be one or both legs or arms.

During the examination, the technologist will mark the course of the veins. This is done with a permanent marker.

What can I expect after the test?

You will not be allowed to bathe or wash the area that has been marked with the marker. This is very important.

The report will be forwarded to your physician, who will discuss them with you at a later time.
