Renovascular hypertension is a potentially curable form of high blood pressure. However, it is unclear how best to select patients who are likely to have renovascular hypertension, what diagnostic strategy to use in these selected patients, and how to predict the hemodynamic significance of a renal artery stenosis. We determined the prevalence of renovascular hypertension in adults who exhibite...

The most common clinical manifestations of fibromuscular dysplasia (FMD) are hypertension due to renal artery involvement and transient ischemic attack or stroke due to carotid or vertebral artery involvement. Patients with renal artery FMD and hypertension should undergo primary angioplasty with the goal of curing the hypertension. If the blood pressure fails to normalize following angioplasty...

We describe our preliminary experience with percutaneous renal denervation in end-stage renal disease patients with resistant hypertension and challenging anatomy, in terms of the feasibility, safety, and efficacy of this procedure. Four patients with end-stage renal disease patients with resistant hypertension (mean hemodialysis time, 2.3 years) who had been taking at least four antihypertensi...

RATIONALE Iliac arterial fibromuscular dysplasia (FMD) was rarely reported and its demographic, clinical, and imaging features have not been precisely described resulting in uncertain therapeutic methods. PATIENT CONCERNS A 31-year-old man was referred because of 3-month-ago onset hypertension, low serum potassium, and a small-sized right kidney with normal renal artery under ultrasound exami...

BACKGROUND Calcifications in arteries are thought to represent atherosclerosis. METHODS Consecutive abdominal tomographic scans performed during a 4-month period were evaluated and assessed for renal artery calcifications (RAC). Scans that showed calcifications were evaluated for renal artery narrowing and for various characteristics of the atherosclerotic plaque. RESULTS Of 350 consecutive...

Hypertension affect about 1% of patients with neurofibromatosis type 1 (NF1). Major causes are concomitant pheocromocytoma in adults and renovascular hypertension in children. In most cases, NF1 is associated with renal artery stenosis, smooth cell proliferation and advential fibrosis. We describe a 16 year old girl with hypertension complicating NF1 secondary to severe coarctation of abdominal...

Renovascular occlusive lesions account for the most common form of surgically correctable hypertension. Technical advances in vascular reconstructive surgery have increased the likelihood of renal parenchymal preservation and amelioration of hypertension in patients having renal artery stenoses. Proper selection of patients alleged to have renovascular hypertension for operative treatment is th...

BACKGROUND Aorta Coarctation (AC) is uncommon condition that in most adult patients is asymptomatic. Diagnosis of AC is made during routine physical examination by detection of Blood Pressure (BP) difference between arm and leg. AIM To describe a novel renal artery Doppler flow pattern pathognomonic of aortic coarctation. METHODS We enrolled 4 consecutive patients referred to renal artery D...

Malignant hypertension is the most severe form of hypertension that is usually fatal if not properly managed. It is usually associated with evidence of microvascular damage such as retinopathy and nephropathy. Renal artery embolization is a widely utilised tool for the management of a wide range of conditions including drug resistant renovascular hypertension in patients with end stage renal fa...
