title: Left subclavian artery stenting: an option for the treatment of the coronary-subclavian steal syndrome.
abstract: BACKGROUND
  The subclavian steal syndrome is characterized by the vertebral artery flow inversion, due to a stenotic lesion in the origin of the subclavian artery. The Coronary-subclavian Steal Syndrome is a variation of the Subclavian Steal Syndrome and is characterized by inversion of flow in the Internal Thracic artery that has been used as conduct in a myocardial revascularization. Its diagnosis must be suspected in patients with difference in pulse and arterial pressure in the upper limbs, that present with angina pectoris and that have done a myocardial revascularization. Its treatment must be a surgical bypass or a transluminal angioplasty.
  
  
  OBJECTIVE
  The objective is to show the left subclavian artery stenting as a safe and effective method to treat the coronary-subclavian steal syndrome.
  
  
  METHODS
  Historical prospective, non-randomized trial, through revision of the hospital records of the patients treated with the stenting of the left subclavian artery, from January 2006 to September 2012.
  
  
  RESULTS
  In the mentioned period, 4.291 miocardial revascularizations were performed with the use of the left mammary artery, and 16 patients were identified to have the Coronary-subclavian steal syndrome. All of them were submitted to endovascular treatment. The success rate was 100%; two patients experienced minor complications; none of them presented with major complications. Eleven of the 16 patients had ultrassonographic documentation of patent stent for at least one year; two patients lost follow up and other two died.
  
  
  CONCLUSIONS
  The stenting of the left subclavian artery is a good option for the treatment of the Coronary-subclavian Steal Syndrome, with high level of technical and clinical success.
