  • Title: Bilaterial renal artery atherosclerosis--the results of surgical treatment.
    Author: Crinnion JN, Gough MJ.
    Journal: Eur J Vasc Endovasc Surg; 1996 Apr; 11(3):353-8. PubMed ID: 8601249.
    Abstract:
    OBJECTIVES: To assess the outcome of surgical treatment for severe bilateral renal artery stenosis. DESIGN: Non-randomised, prospective, consecutive series. MATERIALS: Twenty-five patients undergoing surgical reconstruction of whom 14 required aortic replacement (aneurysm, n = 7, severe claudication, n = 7). In 22 patients, the principle aim of treatment was preservation or salvage of renal function whilst three patients had intractable hypertension. METHODS: Serum creatinine and blood pressure were measured at the most recent follow-up (minimum 6 months, median 17 months) and compared to preoperative values. RESULTS: Renal function (serum creatinine) improved or stabilised in 16 of 18 patients in whom it was elevated preoperatively (>140 mumol/l; 3 patients on dialysis) whilst one patient with early graft occlusion subsequently required long term dialysis. Blood pressure control was also improved in 14 patients. There were four postoperative deaths (16%) and five patients required re-exploration for postoperative anuria (3) or bleeding (2). CONCLUSIONS: Surgical revascularisation preserves renal function and may improve blood pressure control in patients with advanced multi-system atherosclerosis. The operative morbidity and mortality is significant although historical data suggests that this is less than for similar patients treated medically.
