Upper/Lower Extremity Arterial Duplex

Duplex imaging is used to determine exact location and the extent of an arterial obstruction without angiography, permitting the Physician to discuss potential interventions with the patient.


  • Claudication with resting Ankle Brachial Index (ABI) less than .80 and exercise ABI less than .70.
  • A .15 drop in ABIs when compared to previous study.
  • Leg and/or arm pain, numbness or weakness with exertion.
  • Loss of or reduced pulse in arm or leg.
  • Cyanosis of digits, or cold extremity to the touch.
  • Trauma to the extremity with suspected arterial injury.
  • Asymmetrical Brachial pressures equal or greater than 20 mmHg (suggestive of Subclavian Steal).
  • Postoperative evaluation of hemodialysis access graft or arterial bypass.
  • Monitoring a bypass graft.
  • After percutaneous interventions such as angioplasty, for monitoring or if symptoms change.
  • Pulsatile mass in arm or leg.
