PERCUTANEOUS TRANSLUMINAL ANGIOPLASTY OF RENAL-TRANSPLANT ARTERIES STENOSIS - LONG-TERM

A hundred and ninety five percutaneous transluminal angioplasty (PTA) of a renal transplant artery were attempted before january 1st, 1990 i n 151 patients. Analysis of the series was essentially based on follow -up after PTA. PTA was initially successful in 85% of the patients. Re stenoses occurred in 30% of the patient. They were usually amenable to repeat PTA. Restenosis rate after repeat PTA was of 26%. The five yea r secondary patency rate of the renal artery was over 85%. After a suc cessful PTA, the blood pressure, the number of antihypertensive drug p er patient and serum creatinine returned to a level close to their bas al value within few days and remained stable long.
