Doppler ultrasound examination of neck arteries

Circulation, width and deviances of the neck arteries that go to the brain  (arteria carotis and vertebralis), and the artery below the collarbone (arteria subclavia) can be examined with this method.

Detailed elaboration

Doppler ultrasound examination of the neck arteries are suitable for exploring the circulation and width of these vessels. During the examination, circulation is shown using two methods, hence the term Duplex.

In what cases is the examination advised?

  • in a state following a circulatory deficiency of the brain
  • after a temporary deficiency of vision
  • after a stroke
  • if a sputter can be heard above the neck arteries
  • examination before a heart surgery
  • exploring the extent of sclerosis within the vessels in case of risk factors
  • checking progress after treatment of the carotis
  • as part of the examinations that explore the state of vessels of male patients suffering from erectile dysfunctions

During the examination, we check the diameter, direction, thickness and deposition within the vessels. Extensive constriction is indicated by circulatory signals, such as its quickening or a change of its nature.
As part of the examination, the artery running along the upper part of the spinal column (arteria vertebralis) and the artery below the collarbone (arteria subclavia) are also checked regarding their circulation.

Preparation:

Preparation is not necessary. However, the neck must be made available. It is advised that before the examination, necklaces should be removed and put away.

Limits, further examinations

The examination might be made more difficult in the case of certain factors, such as having a short or thick neck. If severe constrictions are found, vascular surgical examination is advised, and to plan further treatment, CT angiograph or cathetered angiograph might be necessary. These can be advised by a radiologist or vascular surgeon.
