title: Percutaneous transluminal angioplasty of dysplastic stenoses of the renal artery: results on 70 adults.
abstract: OBJECTIVE
  Retrospective analysis of the dilatation (PTRA) of renal arterial dysplastic stenosis (RADS).
  
  
  METHODS
  Seventy patients suffering from hypertension (87 RADS) were treated at our institution for medial (83%) or non-classified fibrodysplasias (17%). Four patients suffered from renal insufficiency. Two endoprostheses were implanted. We evaluated blood pressure with the USCSRH criteria and renal insufficiency with the Martin criteria.
  
  
  RESULTS
  Ninety-five percent technical success and 87.9% clinical success for blood pressure were obtained, with worse results for patients older than 57 years or with a history of hypertension greater than 9 years. Results were better when the RADS was responsible for an ipsilateral renal atrophy or for poorly controlled hypertension. No renal insufficiency worsened during the follow-up.
  
  
  CONCLUSIONS
  PTRA is a first-line treatment for renovascular hypertension caused by RADS. The results were encouraging despite a high average age of the subjects and frequent associated extrarenal vascular lesions.
