If the arm/upper extremity is the area of concern we will assess the subclavian, axillary, brachial, basilic, cephalic, radial and ulnar veins.

What can a Peripheral venous ultrasound see?

The peripheral venous ultrasound can identify if there are any deep or superficial clots and assess the quality of the blood flow in the arteries in the legs.

What happens during the Peripheral venous scan?

The sonographer will have you remove your trousers and lay on the bed facing up. A transducer/camera is placed on the leg starting at the junction of the leg and hip and the sonographer will scan the leg down to the ankle on each side. The sonographer will also have to push down on the leg in various locations to assess the compressibility of the veins. During the exam you may hear a noise that sounds like waves or wind, this is the venous blood flow within the legs.

How long will the exam take?

The scheduled time for this exam is usually 45 minutes - 1 hour for both legs.

Who will report my vascular exam?

After the sonographer has completed your exam the images will be sent to a consultant radiologist who will report your scan.

When will I receive my results?

You will get verbal results from the sonographer at the end of the examination however it is up to the radiologist to make a final report. The formal report will be sent to your GP by post which may take up to 5 days. If you are self-referred it may also take up to 5 days for you to receive the formal report by email. If there are urgent findings the process will be expedited and faxed to your GP within 24 hours.
