Renovascular Disease

New Insights Into Pathophysiology, Diagnosis, and Treatment of Renovascular Hypertension.

Renovascular disease includes renal artery stenosis, renovascular hypertension, and azotemic renovascular disease (ischemic nephropathy). Renovascular hypertension is defined as an elevated blood pressure caused by renal hypoperfusion, usually resulting from anatomic stenosis of the renal artery and activation of the renin-angiotensin system. It accounts for 1% to 2 % of all cases of hypertensi...

Renovascular hypertension due to Buerger's disease.

In a 42-year-old man with severe hypertension, stenosis of the left renal artery at its origin and occlusion of the abdominal aorta below the level of the renal arteries were observed. His past history and clinical and laboratory findings suggested that the renal artery stenosis was due to Buerger's disease which was reported to be a rare cause of renovascular hypertension.

Altered Release of Cytochrome P450 Metabolites of Arachidonic Acid in Renovascular

The aim of the present cross-sectional study was to investigate whether activation of the renin-angiotensin system in renovascular disease affects the cytochrome P450 / -1 hydroxylase (20-hydroxyeicosatetraenoic acid [20-HETE]) and epoxygenase (epoxyeicosatrienoic acids [EETs]) pathways of arachidonic acid metabolism in vivo, each of which interacts with angiotensin II. Plasma concentration and...

Society of Nuclear Medicine Procedure Guideline for Diagnosis of Renovascular Hypertension

Renovascular disease includes renal artery stenosis, renovascular hypertension, and azotemic renovascular disease (ischemic nephropathy). It is important to distinguish between renovascular hypertension and renal artery stenosis. Stenosis of the renal artery is common in nonhypertensive elderly persons and is an associated but noncausative finding in a number of hypertensive patients. Renovascu...

Prevalence of renovascular abnormality in patients undergoing cardiac catheterization.

OBJECTIVE To determine the prevalence of renal artery disease and to correlate the underlying risk factors like age, sex, diabetes, hypertension, urea and creatinine in patients who have undergone angiogram for cardiovascular diseases. METHODS Retrospective analysis of the reports of angiogram of patients who have undergone cardiac catheterization in Vijaya Heart Foundation for cardiovascular...
