title: Subclavian carotid transposition: an analysis of a clinical series and a review of the literature.
abstract: OBJECTIVE
  To analyse the clinical results and long-term patency rates of 108 patients with subclavian carotid transposition (SCT) and compare the outcomes to other clinical series using the same technique, as well as to those reported for other surgical procedures and PTA in the treatment of proximal subclavian artery disease.
  
  
  METHODS
  The hospital records of 108 patients with carotid subclavian transposition were retrospectively reviewed for preoperative symptoms, Doppler examination, arteriography, blood pressure differentials and postoperative complications. Long-term patency and symptoms were determined during a follow-up examination including a history, physical examination, blood pressure differentials, Doppler examinations and arteriography in selected cases.
  
  
  RESULTS
  The indication for SCT were subclavian steal (78%), upper extremity ischaemia (59%), rest pain or acral necrosis (5%), vertigo (6%). There was no mortality, blood pressure differentials were equalised in all patients without any early reocclusions. The complication rate was 15% with a permanent morbidity of 3%. Eighty-four patients (77%) could be re-examined during follow-up. For them the overall patency after a mean observation period of 70 months (1-144 months) was 100%.
  
  
  CONCLUSIONS
  Subclavian carotid transposition is an excellent method for the treatment of proximal subclavian occlusive disease because of its exceptional long-term patency and low morbidity.
