THE RESPONSE of individuals with essential hypertension to an acute salt load has been extensively studied.1-5 The response to salt loading in hypertension due to renal artery stenosis, however, has not been well characterized. Recently, Birchall, Madsen, and Anderson," demonstrated that salt loading would magnify the difference in U sodium/U creatinine ratios in unilateral renal artery stenosi...

BACKGROUND AND PURPOSE Renal artery lesions in moyamoya disease have been described sporadically in several case reports. The purpose of this study is to evaluate the angiographic findings of renal artery lesions in moyamoya disease and to determine the prevalence of renal artery lesions in patients with moyamoya disease. METHODS Eighty-six consecutive patients with idiopathic moyamoya diseas...

Renal artery stenosis (RAS) is the leading cause of secondary hypertension. Renal artery stenosis can result in various cardiopulmonary complications mostly through activation of neurohormonal pathways that result in fluid overload and systemic hypertension. We herein describe a 72-year-old man with recurrent rapidly accumulating transudative pleural effusion in a patient with severe bilateral ...

A 21 year old male was discovered to be severely hypertensive. He was found to have bilateral adrenal phaeochromocytomas and a single renal artery stenosis. More than 40 cases of coexisting renal artery stenosis and phaeochromocytomas have been reported. The aetiology of renal artery stenosis in association with phaeochromocytoma maybe multifactorial and the radiographic appearances are not alw...

Renal denervation (RDN), a recently developed therapy for resistant hypertension, is generally regarded as a safe procedure (Krum et al., 2009; Esler et al., 2010; Bhatt et al., 2014). The Symplicity HTN trials reported that the rate of renal artery stenosis after RDN was low. For example, the Symplicity HTN-1 trial showed that 1 of 45 (2.2%) denervated patients developed a non-obstructive rena...

Secondary hypertension is a type of hypertension with an underlying, potentially correctable cause. A secondary etiology may be suggested by symptoms (e.g., flushing and sweating suggestive of pheochromocytoma), examina- tion findings (e.g., a renal bruit suggestive of renal artery stenosis), or laboratory abnormalities (e.g., hypokalemia suggestive of aldosteronism). Secondary hypertension als...

BACKGROUND Renal artery stenosis (RAS) is an important clinical entity that can lead to uncontrolled hypertension and progressive renal failure. The most common causes of RAS are atherosclerosis and fibromuscular dysplasia. Because the diagnosis of renovascular hypertension is established only when revascularization of a stenosed renal artery results in cure or improvement in patients hypertens...

OBJECTIVE: The purpose of this study was to evaluate the association between the presence of clinical symptoms of peripheral artery disease and severe renal artery stenosis in patients referred for renal angiography. METHOD: We included 82 patients with clinical suspicion of renovascular hypertension and performed an imaging investigation (renal Doppler ultrasound and/or renal scintigraphy) f...

Background Renovascular hypertension due to fibromuscular dysplasia is an uncommon cause of secondary hypertension and is more common in females. This entity is an important treatable cause of secondary hypertension. Case presentation We report the case of a 21-year-old asymptomatic male found to have high blood pressure on routine checkup. Renal angiogram revealed fibromuscular dysplasia inv...
