renal artery stenosis With renal artery stenosis, ‘stenosis’ means narrowing, which refers to a progressive narrowing of the renal artery, which carries blood to the kidney.This means that the blood downstream of the narrowed spot that goes to the kidney is at lower pressure, which gets sense...
A renal angiogram demonstrated left renal artery stenosis with increased left renal vein renin activity. The hypertension resolved within 24 h of a left nephrectomy, but non-nephrotic-range proteinuria persisted for 8 months post operatively. Pathology of the left kidney was consistent with ...
Renal Artery Stenosis Basics Basics Basics DESCRIPTION DESCRIPTION DESCRIPTION Narrowing of one or both renal arteries and/or their more distal branches, resulting in decreased perfusion, increased renin release, increased vascular resistance, and systemic hypertension EPIDEMIOLOGY EPIDEMIOLOGY EPIDEMIOLOGY Hyper...
Renal Artery Stenosis IdoWeinberg,Michael R.Jaff, inCardiovascular Therapeutics: A Companion to Braunwald's Heart Disease (Fourth Edition), 2013 Conclusion ARASis prevalent and has potential serious medical consequences, and treatment options include medical andinterventional therapies. Despite clear understa...
The practical value of renin secretion studies in hypertension associated with unilateral kidney disease, other than renal artery stenosis, has not been documented. This study, comprising 19 patients of this kind, disclosed three who had an abnormal renin secretion from the diseased kidney. The ...
A functionally important associated renal artery stenosis in the presence of a RAA remains a valid indication for intervention. Coexistent renal artery stenosis has been identified in 7% to 66% of patients with RAA, but it does not explain every case of improvement following surgery.1, 7, 9, ...

Renal artery stenosis (RAS) was defined as a luminal narrowing >50. Of the 366 patients investigated, 112 (31) had RAS, of whom 41 had bilateral RAS. Patients with RAS were older (P < 0.001), had higher blood pressure (P < 0.001), and worse renal function (P= 0.001). In addition...
Six months after adrenalectomy (histopathological examination showed an aldosteronoma) high blood pressure with high level of aldosterone and low renin concentration was observed. Further investigation revealed stenosis of the rightrenal artery with enlarged right adrenal gland. The diagnosis of 'tertiary...
The mechanism for the development of hypertension with renal artery stenosis, however, appears to be more complex. Although atherosclerotic renal activation of the renin-angiotensin-aldosterone system by renal hypoperfusion is essential for initiating the pressor response, it is transient. Over time, ...
