Comprehensive Vascular Lab

At DVVI, we offer a comprehensive non-invasive vascular lab within our center. That means all vascular testing including ultrasound exams are performed on site. Patients do not need a referral to an outside hospital or imaging center.

Vascular exams are performed by our highly-experienced sonographers certified in Diagnostic Medical Sonography.

The non-invasive vascular lab at DVVI offers:

Ankle- Brachial Index (ABI)

  • Performed by measuring blood pressure at the ankle and in the arm while a person is at rest. The index is calculated by dividing the systolic blood pressure at the ankle by the systolic blood pressure in the arm
  • Used to screen and predict the severity of peripheral arterial disease (PAD)
  • Used to see how well a treatment is working (such as medical treatment, an exercise program, angioplasty, or surgery)

Treadmill ABI

  • An exercise stress test in which the blood pressure measurements are repeated at both sites after a few minutes of walking on a treadmill.
  • Can detect a significant drop in blood flow, indicating a narrowing or blockage within an artery, that a resting ABI may not detect

Venous Ultrasound

Lower extremity:

  • Venous insufficiency/ varicose veins
  • Acute or chronic deep venous thrombosis (DVT)
  • Venous stasis/ ulcer

Upper extremity:

  • Mapping for dialysis fistula or graft planning
  • Acute or chronic DVT
  • Compression syndromes such as thoracic outlet syndrome

Abdominal and pelvic:

  • Inferior vena cava/ renal veins
