Abstract

Renovascular disease is the leading cause of surgically-curable arterial hypertension and one of the few cause of reversible chronic renal failure, but its exact prevalence remains unknown. Progression of atheromatous disease occurs in 50% of cases and it may result in bilateral stenosis (25%) or total occlusion (15%). By now, the main aim of renal revascularization is retrieval of impaired function or prevention of renal failure rather than control of hypertension. However, renal functional deterioration may result from cholesterol embolism or glomerulosclerosis in addition to ischemia. Correction of post-proximal stenosis is obtained by both surgery and percutaneous angioplasty. In favor of angioplasty are a higher acceptability and a modestly better cost-benefit ratio. Surgery may be preferred when the stenosis is proximal, complex or associated with aortic disease; in addition, analysis of published (mostly uncontrolled) series suggest that beneficial renal functional outcome is slightly better following surgery. Importantly, both diagnosis and prognosis of ischemic nephropathy are difficult to establish. Various predictors of recovery (renal size, renal vein renin ratio, alteration in scintigrams, angiography or biopsy) we...Continue Reading

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
