Vascular
Ultrasound Lab

• 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.

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 

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

Abdominal 

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

• 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.

• 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.

• Musculoskeletal 
• Bladder
