Non-Invasive Vascular Services




Non-invasive vascular services at Baylor Scott & White Heart and Vascular Hospital – Dallas are used to diagnose a wide variety of conditions and abnormalities of the circulatory system, including blockages, clot formation and aneurysms in the arteries and veins, and to locate specific areas for study. Diagnostic testing in the non-invasive department often achieves results similar to those of more invasive procedures, but with less risk and no radiation exposure to the patient.

The non-invasive vascular lab is accredited by the Intersocietal Accreditation Commission (IAC) in peripheral venous, peripheral arterial and extracranial cerebrovascular duplex (carotid Doppler) examinations. The non-invasive department has been accredited in vascular testing since 2005 with specially trained and nationally-registered sonographers. The physicians on the medical staff include board-certified vascular surgeons, cardiologists and other specialists.


We offer comprehensive non-invasive vascular care, including carotid ultrasound to evaluate any blockages or narrowing in the arteries leading to the brain, venous ultrasound, abdominal ultrasound to diagnose and evaluate abdominal aortic aneurysm (AAA), and vein mapping for dialysis access and bypass grafts. We also provide physiologic testing (blood pressure measurements) to evaluate for blockage in the arteries of the legs and the arms.

Our services include:
  • Venous ultrasound – Venous ultrasound involves the use of high-frequency sound waves to produce real-time images of the veins. Diagnosis and treatment plans can thus be determined quite simply and easily.
  • Non-invasive arterial studies and ultrasound – A form of testing in which ultrasound waves measure the speed and direction of blood flow to diagnose blockages.
  • Ankle brachial indexes (ABIs) – For this test, blood pressures are taken at the arm and ankle, and then the ankle pressure is divided by the arm pressure giving a ratio the physicians will use to determine severity.
  • Segmental pressures – Segmental pressure is similar to ABI, but it involves two or three additional blood pressure cuffs. They are placed just below the knee, just above the knee and at the upper thigh. Blood pressures are recorded at each point and significant drops between body segments may suggest blockages or narrowing in the arteries.
  • Cerebrovascular ultrasound (carotid) – For this test, ultrasound is used to view the carotid arteries that lead to the brain and assess for narrowing and blockage. If an abnormality is found, a treatment plan may be put in place.

Frequently Asked Questions


 

Where do I park?

Self-parking is available adjacent to the hospital in Lot 19 or Garage 10. Valet parking is available at the hospital's entrance off Junius Street.

Where do I go?

When you arrive, you will need to visit our Access Services desk where you will be greeted and checked in. Our access services team will collect any co-payment due as well as have you sign the appropriate consent forms. Once you are completely checked in, your access services representative will arrange for your transport to the non-invasive department.

How long will it take?

Most of our procedures are short, but plan on spending a couple of hours to account for checking in on the ground floor, walking to the department, and completing your test.
