BACKGROUND: Renal artery stenosis comprises both atherosclerotic renovascular disease and fibromuscular dysplasia, and may be associated with refractory hypertension, acute 'flash' pulmonary oedema and renal failure. The long-term clinical effects of renal artery stenting remain unclear.
AIM: To assess the procedural and long-term safety and efficacy of renal artery stenting and its effect on blood pressure, antihypertensive medication usage and serum creatinine.
METHODS: All patients referred for renal artery stenting at our institution between September 1997 and December 2003 were entered into a prospectively collected database. Systolic and diastolic blood pressure, number of antihypertensive medications, serum creatinine and estimated glomerular filtration rate (eGFR) were recorded. Patients were followed-up at least six months post-procedure.
RESULTS: Eighty-nine patients underwent renal arteriography, with 110 stents deployed in 102 lesions. The procedural success rate was 99% with no procedural mortality. There were two cases of peri-procedural haemorrhage and one of sepsis. One patient developed renal and peripheral atheroemboli.
FOLLOW-UP: Mean follow-up was 28 months (range 6 months-7 years). Eight patients were lost to follow-up. There were nine deaths with a mean time to death of 20.7 months (range 12 months-3 years). There was a highly statistically significant fall in systolic blood pressure (BP) from 161.7+/-29.5 mmHg pre-procedure to 138.7+/-17.9 mmHg at long-term follow-up post-procedure (p<0.0001). The clinical restenosis rate was 6.2%. Renal function and eGFR remained stable and there was a borderline significant decrease in the number of antihypertensive medications used (p=0.05).
CONCLUSION: Renal artery stenting is safe and appears effective for the treatment of clinically significant renal artery stenosis.
