An in-depth scan to gauge abnormal valve and vein functions.

An in-depth venous duplex ultrasound scan is carried out on each patient at Advanced Vein Institute of Arizona to identify and gauge abnormal valve and vein functions. Our experienced ultrasonographers Karlea or Susan will evaluate the blood flow and map the venous system of both lower extremities. We use cutting-edge imaging capabilities, ZONE Sonography® Technology (ZST), to allow your vein doctor to determine which veins are normal and which require treatment or monitoring.
Ultrasounds are also used after treatment to confirm vein closure as well as rule out any complications such as Deep Vein Thrombosis (DVT). In addition, you may be referred to our vein center by your primary care physician, urgent care, or podiatrist in order to rule-out DVT. In this case, we schedule you the same-day and call your referring doctor with duplex ultrasound results immediately.

During the vein ultrasound, you may feel some discomfort or pressure if your leg is tender prior to the scan, however, this examination is typically painless. It takes approximately 1 hour to complete this duplex ultrasound, and patients should be very well hydrated prior to their appointment. We ask all patients to drink at least 64 ounces of water a day for the three days leading up their initial ultrasound, and avoid compression stocking use the day of the evaluation.
