title: Percutaneous transluminal angioplasty in patients with Takayasu arteritis: five-year experience.
abstract: OBJECTIVE
  The authors report their 5-year experience with percutaneous transluminal angioplasty (PTA) for treatment of stenoses related to Takayasu arteritis.
  
  
  METHODS
  Twenty patients were treated; 12 patients had renovascular hypertension at presentation, three patients had abdominal aortic coarctation syndrome, and five patients had aortoiliac occlusive disease.
  
  
  RESULTS
  The initial success rate for patients with renovascular hypertension was 83%, with a 5-year patency of 33.3%. In patients with abdominal aortic coarctation, initial success rate was 100% but 5-year patency was 33.3%. In patients with aortoiliac occlusive disease, the initial success rate was 100%, with a 5-year patency of 60%.
  
  
  CONCLUSIONS
  Despite the high initial success rate for PTA in these patients, the disease recurs in a substantial number of the, due to the fact that this technique does not treat the disease itself but only its consequences.
