• Diagnosing subclavian steal syndrome icon plus

  Your consultant will discuss your symptoms with you.

  The following tests can be carried out if they suspect you may have subclavian steal syndrome:

  • Physical examination to assess general health, including bloody pressure and arm movement.
  • Ultrasound imaging to help determine the extent of arterial blockage
  • Angiography to monitor blood vessels. A special dye is inserted into your blood. The vessels will then be visible on X-Ray.

• Potential treatment options icon plus

  Your consultant will discuss your treatment options and help determine the best possible approach for you. These might include:

  • An angioplasty. Your surgeon will carefully inflate a small balloon inside your artery to open its walls. A stent can be inserted to help keep the artery open and limit blockage
  • An endarterectomy is a surgical procedure that removes the plaque (fatty deposits) blocking or narrowing your affected artery. This allows blood to flow more freely through the aortic arch
