[PTA of 131 renal artery stenoses: management of hypertension and organ support].
In this study 106 hypertensive patients (male n = 63, female n = 43) with angiographically proven renal artery stenosis (RAS) had PTA in 131 renal arteries (AS n = 86, FMD (fibromuscular dysplasia) n = 16, renal transplant n = 3, aortorenal bypass n = 1). Technical success rate was 86%, major complications were 3.5%, and minor complications were 12.8%. Following PTA (3-52 mo.) blood pressure was normalised in 25% (23/91), improved in 44% (40/91), and remained unchanged in 31% (28/91). Elevated serum creatinine levels (n = 26) (mean of 2.4 mg% before PTA) were regredient in 13 cases, remained stable in 6 cases, and were progredient in 7 cases. In short ostial RAS, technical and clinical results were not satisfactory. Long-term results were found to be better with FMD than with arteriosclerosis, with normal creatinine than with elevated levels, residual RAS after PTA of less than 50%, and with normal contralateral kidney function.
