Ischemic nephropathy: clinical characteristics and treatment.
Ischemic nephropathy is a long-term cause of hypertension and renal failure. Although its real incidence is unknown, ischemic nephropathy is growing because of the increased mean age of the population and the greater prevalence of hypertensive and diabetic populations. This review describes the clinical profile of afflicted patients. Atherosclerosis in different vascular beds is common in these patients. The evolution of ischemic nephropathy is generally progressive, although some patients present with acute renal failure, either secondary to the administration of angiotensin-converting enzyme inhibitors or caused by thrombosis of the renal arteries. Revascularizing surgery may stabilize or improve renal function, even in patients with nonfunctioning kidneys. The results obtained with intraluminal angioplasty are worse, with a high percentage of restenosis. Placement of an endoprothesis is recommended when the lesions affect the ostium or proximal third of the artery. This complex disease typically affects multiple organs, thus making individual assessment essential.
