Overview

Subclavian steal syndrome occurs when there is a narrowing of the artery, due to the build-up of plaque, which supplies blood to your arms. This condition mostly happens on the left subclavian artery which branches off from the aorta.

Symptoms

Most people do not have any symptoms because other blood vessels can compensate and supply blood to the arms. Symptoms of subclavian steal syndrome in the affected arm include:

  • Muscle cramping
  • Pain or tiredness when the arm is used
  • Tingling or numbness 
 

Tests

Computerized Tomography (CT) Scan

CT angiography is a diagnostic test combines the technology of a conventional CT scan with that of traditional angiography. It can assess blood vessels noninvasively often just as well as the traditional angiogram, but with much less risk to the patient.

Treatments

Subclavian steal syndrome treatments may include:

  • Medication – Aspirin, medications to lower blood pressure, and statins or other cholesterol management drugs.

  • Angioplasty
    Angioplasty is also a common procedure used by vascular surgeons to treat the narrowing and blockages of the peripheral arteries. An inflatable balloon is used for opening arteries and stents are often used to prevent the recurrence of blockages in the future.
