Arterial Doppler

   1. Purpose of Test

The Arterial Doppler study is able to demonstrate blocked or reduced blood flow through the major arteries of the arms and legs. It is used to evaluate:
• Numbness and tingling sensations in the hands, arms, feet and legs
• Sensation of fatigue and heaviness in the arms and legs
• To investigate the possibility of thoracic outlet syndrome.

   2. What to expect during procedure

For the Arterial Doppler exam a blood pressure cuff is applied to each of the arms and legs and a pressure is recorded for each extremity cuff. The pulse is also taken and recorded for each of the extremities. The patient may then be exercised and blood pressure recordings repeated or an ultrasound may be performed to assess the arteries for the location and the amount of narrowing.
When evaluating for thoracic outlet syndrome of the upper extremities, the patient will be asked to perform a series of arm movements while recordings are documented.

The Arterial Doppler studies take approximately 60-90 minutes.

   4. When results will be available
