BACKGROUND Recent studies have reported elevated prostaglandin levels in patients with renal artery stenosis and hypertension. To investigate whether a distinction between essential hypertension and hypertension with renal artery stenosis is possible by measuring eicosanoid excretion, we studied the excretion of these compounds in patients with essential hypertension and in hypertensives with c...

Eklöf, H. 2005. On renal artery stenosis. 54 pp. Uppsala. ISBN 91-506-1824-5. Renal artery stenosis (RAS) is a potentially curable cause of hypertension and azotemia. Besides intra-arterial renal angiography there are several non-invasive techniques utilized to diagnose patients with suspicion of renal artery stenosis. Removing the stenosis by revascularization to restore unobstructed blood flo...

Renal artery stenosis is the most common cause of secondary hypertension. Over 90% of renal artery stenoses are caused by arteriosclerosis, the remainder resulting from fibromuscular dysplasia which usually does not lead to progressive azotemia and end stage renal disease. Renal angioplasty is the treatment of choice for fibromuscular dysplastic disease and has the potential of curing hypertens...

FERRARIO, CARLOS MARIA. Contribution of cardiac output and I periphral resistance to experimental renal hypertension. Am. J. Physiol. 226(3): 71 l-71 7. 1974.-An early increase in cardiac output accompanies development of hypertension due to cellophane perinephritis. The question arose whether a similar hemodynamic response follows rise in blood pressure after constriction of a renal artery. El...

To examine the sequential renal hemodynamic changes in experimental renovascular hypertension, the uninephrectomized dog was studied immediately after renal artery constriction, throughout chronic benign hypertension, and during malignant hypertension. Intrarenal resistance fell immediately after renal artery constriction, but rose above control within hours. Intrarenal infusion of teprotide re...

Renal artery stenosis and renovascular hypertension are important considerations in patients with hypertension that is difficult to control. The diagnosis may also have prognostic significance for progressive renal disease. The most common causes of renal artery stenosis are atherosclerotic disease and fibromuscular dysplasia. The pathophysiology of renal artery stenosis is reviewed, and the pr...

BACKGROUND Acute renal artery thrombosis is a devastating complication of renal transplantation that can result in graft loss if not detected early. Surgical and technical errors are the major cause of renal artery thrombosis. In this article, for the first time, we are reporting a case of acute renal artery thrombosis that developed early post-transplantation due to distal renal artery stenosi...

BACKGROUND Renal artery stenosis is a common cause of secondary hypertension refractory to medical therapy. Percutaneous angioplasty along with metallic stent placement has been described as an effective treatment for revascularization of the renal artery. CASE REPORT A 54-year-old woman affected by paranoid schizophrenia with a history of hypertension and chronic renal failure due to renal a...
