Pseudoaneurysm Ultrasound

A Pseudoaneurysm Ultrasound is an ultrasound scan of the arteries, predominately those in the groin region, to see if a pseudo- aneurysm is present or not.  Pseudo-aneurysms can occur in any artery that has been needled or punctured. Occasionally it may involve the arm arteries. A pseudo-aneurysm (or false aneurysm) is usually a complication that follows puncturing of the artery in your groin or arm . This is most commonly after angiography, surgery or trauma from an accident.

The hole from the puncture usually seals with pressure following your procedure. Occasionally, flow persists out of the artery into the surrounding tissue creating a collection of blood in the tissues which causes pain, swelling and bruising.

The Procedure

  • You will be taken to a private room. A staff member will explain the procedure and answer any questions you may have.
  • You will be asked to remove clothing to access the area to be examined and to lie down on a couch.
  • Gel is placed on the area of interest so that the sound waves can pass through to the relevant vessels. The arteries will be assessed above, at the site and below the site of the suspected pseudo-aneurysm.
  • You will hear the Doppler ultrasound from time to time as it makes a pulsing noise.
  • Often, the groin area is very tender, so please inform the sonographer if it is painful during the ultrasound scan.
  • If the doctor strongly suspects a pseudo-aneurysm, they may have given you some painkillers before the appointment time. If a pseudo-aneurysm is diagnosed, and if the Doctor requests, the sonographer can apply pressure to the hole in the artery and attempt to stop the blood flow. This can be uncomfortable. Please let the sonographer know if it’s too painful.
  • The examination takes 30 minutes
