Vascular studies pertain to an examination of blood vessels, either arteries or veins. These studies are non-invasive which means that the tests are performed without actually entering your blood vessels in any manner.
These tests require no medications, dye, needles or incisions and involve studies of the arteries, veins and carotids.
Equipment used may include blood pressure cuffs, ultrasound and other sensing machines.
Vascular Studies include:
- Carotid artery ultrasound
- Renal artery ultrasound
- Aorta and peripheral artery ultrasound
- Pulse volume recordings of the upper and lower extremities - thoracic outlet & duplex
- Exercise and treadmill testing of both upper and lower extremities (respectively)
- Venous ultrasound of both the upper and lower extremities
- Venous reflux testing
- Vein mapping
- Arterial mapping studies
- Intra-operative duplex ultrasonography
- Lower extremity graft surveillance
Venous Ultrasound for Reflux
Venous reflux testing with ultrasound is a non-invasive, outpatient test that utilizes high frequency sound waves to obtain images of veins in the arms or legs and evaluate for reflux. This test is used to identify the presence and duration of venous blood flow reversal or reflux in the extremities. It is done when there is suspected chronic venous disease, pain, swelling, pigmentation changes, or ulceration of the lower extremity. This test is used to determine if there are problems with the vessels which may result in varicose veins, pain, and swelling. The sonographer applies an acoustic gel to your extremities being tested. A painless instrument called a transducer is gently moved across that portion of your body to visualize the inside of the veins. A physician interprets the results of this test and makes recommendations.
