Percutaneous transluminal angioplasty of dysplastic stenoses of the renal artery: results on 70 adults.
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.
