Chronic Renal Artery Occlusion: Nephrectomy Versus Revascularization

Surgical management of atherosclerotic renovascular disease

“…In our clinical experience, the factors that favor the recovery of renal function after operation have included severe preoperative hypertension, bilateral or global ASO-RVD as the result of high-grade (>95%) stenosis, or renal artery occlusion and rapidly deteriorating renal function. [10][11][12]15,16 When these features were expressed in their most extreme forms as dialysis-dependent ischemic nephropathy, 70% of the patients who underwent operation were removed from dialysis-dependence. Given the impact of renal function on both the quality and the quantity of life, the definition of predictors of function response after renal artery intervention is an imperative for future investigation.…”

“…From our clinical experience, we have reported on this outcome for several patient subgroups. [10][11][12][13][14][15][16] This retrospective review examines our center's cumulative operative experience with ASO-RVD in consecutive adults with hypertension who underwent treatment during a recent 12-year period. The specific points of interest included: 1, preoperative predictors of dialysis-free survival; 2, blood pressure and renal function response to operation; and 3, relationship between blood pressure and renal function response to operation and survival free of dialysis-dependence.…”

Endovascular treatment of chronic occluded renal artery

“…1,2 Improvement in excretory function was reported in 49% of renal artery occlusion patients who underwent surgical revascularization. 3 There are few reports of renal function improvement after endovascular treatment of occluded renal arteries. 1,2,4,5 Dwyer et al reported improvement in five cases of acute renal failure that underwent successful endovascular treatment.…”
