[Pattern of blood creatinine levels in 140 hypertensive patients after successful percutaneous transluminal angioplasty for renal artery stenosis].
Long term effects on creatinine serum level of successful percutaneous transluminal renal angioplasty were retrospectively studied in 140 patients. 3 groups were distinguished: the first one (80 patients) included unilateral renal angioplasties, with normal contralateral kidney and renal artery; the second group (35 patients) included bilateral renal angioplasties; the third group (25 patients) included solitary kidney renal artery angioplasties. In each group, subgroups were defined whether creatinine serum level was upper or lower than 130 mumol/l. Renal function was considered to be improved if serum creatinine was reduced by 20% or more, maintained if serum creatinine variations were below 20%, worsened if its increase was upper than 20%. Global complication rate was 4.9% (9 between 185 patients) of whom 1 (0.54%) needed a surgical revascularization. At the end of follow-up (mean between 4 and 10 months), subgroups improvement and stabilization rates varied between 67 and 100%, with the best scores in the second group (96.2 and 100%) and solitary kidney with renal insufficiency subgroup (77.25%).
