title: Subclavian steal syndrome: report of 28 cases.
abstract: OBJECTIVE
  To study the experience in the treatment of subclavian steal syndrome (SSS) and the relation between SSS and the damage of brain.
  
  
  METHODS
  In 28 patients with SSS, 23 were operated on. They complained of vertigo, TIA, and claudication of arms. One patient suffered from severe stem ischemia spasm. All the patients were subjected to subtraction angiography. Fifteen of them showed retrograde flow in the vertebral arteries. Transcranial Doppler revealed retrograde blood flow in 8 patients. Single photon emission tomography showed inadequate blood supply to the brain with affected subclavian arteries in 4 patients. Carotid-subclavian arterial bypass was performed in 16 patients, axilloauxillary bypass in 3, PTA in 1, and aorta-carotid graft bypass in 3.
  
  
  RESULTS
  13 patients (13/23) had their cerebrovascular symptoms relieved. Transcranial Doppler and emission tomography after operation showed nothing abnormal.
  
  
  CONCLUSIONS
  SSS is harmful and the patients should be closely monitored by means of transcranial Doppler and emission tomography.
