Non-Invasive Vascular Testing

The Vascular Laboratory at Danbury Hospital is accredited by the Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL) in all five areas of vascular testing. This places our Vascular Laboratory among the top two percent in the nation — or among the 30 best US facilities — offering high-quality testing for vascular disease.

Non-Invasive and Painless

At the Non-Invasive Vascular Laboratory at Danbury Hospital, we perform only non-invasive procedures, tests that are done on the outside of your body and do not involve injecting any contrast dyes, needles, or catheters into your blood vessels. These tests are painless and have no side effects.

ICAVL Areas of Vascular Testing

As defined by the Intersocietal Commission for the Accreditation of Vascular Laboratories, the five areas of vascular testing include:

Carotid Duplex

In this exam, ultrasound is used to evaluate the carotid arteries located in the neck that feed the brain with blood. Gel is applied to the skin of the neck. A transducer is then placed on the gel-covered areas to obtain images and evaluate the blood flow in the arteries. Your doctor may order this test if you have physical examination findings or symptoms that suggest that you may have a blockage in the carotid artery.

Transcranial Doppler (TCD)

This exam evaluates the blood vessels that supply the brain within the skull. It is performed with a small transducer that is placed on the skin of the face and head.

Venous Duplex

During a Venous Duplex or Doppler examination, ultrasound is used to evaluate the veins that carry blood to the heart from the legs or arms. Gel is applied to the skin of the legs or arms. A transducer is then placed on the gel-covered areas to obtain images and evaluate blood flow in the veins. Your doctor may order this to evaluate the cause of pain or swelling in your legs or arms.

Arterial Testing

Arterial Duplex

During an Arterial Duplex or Doppler examination, the ultrasound is used to evaluate the arteries that feed the arms and legs with blood. Gel is applied to the skin of the legs or arms. A transducer is then placed on the gel-covered areas to obtain images and evaluate the blood flow in the arms or legs. Your doctor may order this test to evaluate the cause of pain in the leg muscles with walking.

Arterial Pressures and Waveforms

Ultrasound and blood pressure cuffs are used to evaluate the arteries that supply the arms and legs with blood. Several blood pressure cuffs are placed at different segments on the patient's legs or arms. When inflated, the cuffs provide blood pressure readings as well as waveforms. This test will locate areas of blockage with in the arteries. Your doctor may order this test to evaluate the cause of pain in the leg muscles with walking.

Abdominal Vascular Duplex

During an Abdominal Vascular Duplex or Doppler examination, ultrasound is used to evaluate the blood vessels that bring blood to and away from the abdominal organs. The aorta, the main blood vessel in the body, is also imaged to evaluate for aneurysms and or blockages. Gel is applied to the abdomen. A transducer is then placed on the gel-covered areas to obtain images and evaluate blood flow in the arteries and/or veins.
