Ultrasound Lab

At Northwest Endovascular Surgery we offer a thorough non-invasive vascular lab within our office.  All vascular ultrasound exams are performed on site with a highly experienced registered vascular technologist. 

Our Vascular Ultrasound Lab Offers:


Carotid Artery Duplex

  • Duplex scanning of the extracranial carotid, subclavian, vertebral, and innominate arteries.  
  • Stroke symptoms-visual disturbance, speech disturbance, one-sided weakness or numbness, dizziness or passing out.

Venous Ultrasound 

Lower extremity: 

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

Upper extremity 

  • Acute or chronic DVT
  • Mapping for dialysis fistula or graft planning
  • Thoracic outlet syndrome (TOS)

Abdominal and pelvic 

  • Inferior vena cava and iliac veins 
  • May-Thurner syndrome

Arterial Ultrasound

Arterial Ultrasound 

  • Lower and upper extremity: 
  • Peripheral arterial disease 
  • Aneurysm 
  • Non-healing ulcer 
  • Gangrene 


  • Abdominal aortic aneurysm (AAA) 
  • Aorta-iliac 
  • Mesenteric artery duplex 
  • Renal artery duplex

Ankle Brachial Index (ABI) 

  • Performed by measuring blood pressures at the arm and ankle 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.  
  • Screening tool to predict the severity of peripheral arterial disease.

Treadmill ABI 

  • An exercise stress test in which the blood pressures measurements are repeated at both sites at rest and after a few minutes of walking on a treadmill. 
  • This can detect a drop in blood flow, indicating a narrowing or blockage within an artery.

Non-Vascular Ultrasound 

  • Musculoskeletal 
  • Bladder
