title: Primary endovascular stent placement for focal infrarenal aortic stenosis: long-term results.
abstract: OBJECTIVE
  The objectives of this retrospective study were to determine the technical success, safety, and long-term results of primary stent implantation in infrarenal aortic stenosis.
  
  
  METHODS
  A total of eight atherosclerotic stenoses and one occlusion of the infrarenal aorta (ie, midaortic syndrome) were treated with endoluminal stent placement after balloon angioplasty. Aortoiliac lesions were excluded. Technical success and patency were assessed.
  
  
  RESULTS
  Primary technical success in percutaneous transluminal angioplasty and subsequent stent placement was achieved in all patients. No complications occurred, and no morbidity was encountered. Primary clinical patency rates were 100% on all follow-up examinations. Long-term results with a mean follow-up of 110 months (range, 99-117 months) were recorded in seven patients; one patient had died and one was lost to follow-up.
  
  
  CONCLUSIONS
  In view of the excellent initial results and promising long-term follow-up data in a small series, stent placement after predilation in properly selected patients with isolated infrarenal aortic stenosis appears to be a promising, durable treatment. It should be considered as a primary method of treatment.
