Noninvasive Vascular Laboratory

The Noninvasive Vascular Laboratory (the "Blood flow lab") is one of the key components of the Providence Medford Medical Center Heart & Vascular Program. Noninvasive testing, as the name implies, allows patients to be examined using Doppler ultrasound techniques free of the risks and discomforts of injections and/or other invasive maneuvers. These tests allow diagnosis of almost all known or suspected vascular disorders and testing can often determine the severity of the problems and the need for treatment. A full range of noninvasive tests is available at our Noninvasive Vascular Laboratory including tests for:

Peripheral Arterial Disease (PAD) - blockages in the circulation to the arms or legs due to atherosclerosis or other diseases, which may threaten the limbs.
   • Doppler arterial exams of the legs or arms (physiologic testing)
   • Duplex ultrasound scan of the extremity arteries
   • Treadmill exercise testing for claudication (leg pain with walking)

Cerebrovascular Disease - blockages in the arteries to the brain that may increase the risk of stroke
   • Carotid artery duplex scan

Deep Venous Thrombosis (DVT) - blood clots in the veins that could migrate to the lungs
   • Venous duplex scan of the arms or legs
   • Inferior vena cava (IVC) scan

Renal Artery Disease - circulatory disorders of the kidneys that cause hypertension (high blood pressure) or kidney failure
   • Renal artery duplex scan
   • Duplex scan of the renal veins

Mesenteric Arterial Disease - disorders of circulation to the gut
   • Mesenteric duplex scan

Aortic Aneurysms - a ballooning of the major artery that can cause fatal rupture
   • Aortic duplex scan
   • Duplex scan of peripheral arteries for aneurysms

Chronic Venous Disease - varicose veins and other disorders that cause leg swelling and leg ulcers
   • Duplex scan of the venous valves
   • Photoplethysmography (PPG)

Other specialized examinations
   • Vein "mapping" for peripheral vascular or coronary bypass
   • Arm artery "mapping" for coronary bypass
   • Vascular screening clinics

The Noninvasive Vascular Laboratory facility is designed to serve both inpatients and outpatients with check-in on the 2nd floor of the Providence Pavilion. The vascular laboratory is accredited by the Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL).

QUALITY IMPROVEMENT
Noninvasive vascular testing is most often used to diagnose vascular disorders and assess their severity. However, many of these tests can also be used to measure the effect and success of treatments. Testing after vascular surgery procedures can determine if the vessel has been restored to normal or measure the magnitude of improvement in the flow. As time passes, these tests can also be used to document the durability of a treatment or compare one treatment two another (e.g. angioplasty vs. bypass). Providence Medford Medical Center's noninvasive vascular laboratory is commitment to quality improvement in patient care through continued quality improvement outcome assessments.
