In 78 patients suspected of renovascular hypertension on clinical grounds duplex ultrasound examination of the renal arteries was performed. Renal angiography was used as the standard of reference.

Renal-artery stenosis may occur alone (isolated anatomical renal-artery stenosis) or in association with hypertension, renal insufficiency (ischemic nephropathy), or both.

In a prospective renal artery duplex ultrasound-based progression study, 84 patients with 139 renal arteries with stenosis were followed for a mean of 13 months. Progression of RAS occurred in 42% ...

Renal-artery stenosis, defined as a narrowing of one or both renal arteries or their branches, 1 is most commonly caused by atherosclerosis. Less frequently, it is caused by fibromuscular ...

In addition, while renal arteriograghy is the accepted gold standard for diagnosing renal artery disease, it is well established that percentage angiographic diameter stenosis is an insensitive ...

Renal artery stenosis (RAS) is the narrowing of one or both arteries carrying blood to the kidneys.

New results from a clinical trial testing a novel ultrasound therapy for hypertension show the experimental treatment can deliver clinically meaningful reductions in blood pressure. The treatment ...

Endovascular Ultrasound Renal Denervation to Treat Uncontrolled Hypertension: Primary Results of the Randomized, Sham-Controlled RADIANCE II Pivotal Trial ...

Ultrasound renal denervation injures the sympathetic neurons within the renal artery that contribute to elevated blood pressure.

Renal artery stenting with noninvasive duplex ultrasound follow-up: 3-year results from the RENAISSANCE renal stent trial. Catheter Cardiovasc Interv. 2008; 72: 853-862.

An FDA advisory panel voted 10-2 that the benefits of an ultrasound renal denervation system outweigh the risk for use in adults with uncontrolled hypertension who are unresponsive or intolerant ...
