Surgical Thrombosis Clinic

 
The Vascular Laboratory at Duke University Medical Center is located in Duke South at the 2B Surgery Clinic. All testing we perform is non-invasive and pain free. The tests we perform allow a diagnosis of almost all known or suspected vascular disorders. Non-invasive testing can often determine the severity of the problem and its need for treatment. All testing is performed by a Registered Vascular Technologist (RVT) and are interpreted by a Board-Certified vascular surgeon who is also an RVT.
 
Venous Duplex Scan Upper and Lower Limbs
Venous Duplex scanning has basically replaced Venography as the diagnostic modality of choice in the diagnosis of venous disease. Ultrasound is cost-effective, pain free, non-invasive and very accurate in diagnosing a deep vein thrombosis (DVT) or superficial thrombophlebitis (SVT). In the patient with suspected DVT, a Venous Duplex is now the first test of choice. Besides thrombosis, Venous Duplex exams can assess competency of the venous valves when evaluating for varicose veins or for use as conduit for bypass for the heart and legs.
 
Indications for Testing:
  • Acute leg pain
  • Acute swelling
  • Suspected pulmonary embolism/shortness of breath
  • Heaviness/burning/itching
  • Varicose veins
  • Pre-operative assessment for heart bypass, dialysis access or lower extremity grafts
 
Other non-invasive vascular testing procedures performed include:
 
  • Carotid Duplex: Assessment of the extracranial carotid arteries for stroke prevention.
  • Arterial Duplex: Determine blockage or narrowing within the arteries of the upper & lower extremities.
  • Aortic Duplex: To assess for an abdominal aortic aneurysm (dilation of the aorta).
  • Renal Artery Duplex: To assess flow abnormalities with the renal arteries which could be a cause of hypertension.
  • Arterial Plethysmography and Pressures (PVR/ABI): Determine arterial flow to the digits.
  • Lower Extremity Exercise Stress Studies: Determines if there is a decrease in flow when there is an increase in arterial demand.
  • Arterial Mapping: A comprehensive test for patients who cannot withstand angiography.
  • Venous Mapping: Determine vein size and patency for vascular access and/or arterial bypass surgery.
  • Graft Duplex: Imaging of arterial reconstruction of the upper and lower extremity.
  • Dialysis Access Evaluation: To determine flow rates of fistulas and grafts for hemodialysis.
