To better understand the pathology of renal artery stenosis, we used pre-intervention intravascular ultrasound (IVUS) to study 58 atherosclerotic renal artery lesions (49 ostial, 9 nonostial) in 36 pts undergoing stent implantation for renovascular hypertension. Measurements included reference and lesion...
Upon reaching the renal hilum, the main renal arteries divide into anterior and posterior segmental arteries. These further divide to feed the multiple segments of the kidney. The segmental arteries, in turn, give rise to the interlobar arteries which course alongside the renal pyramids toward the...
Patients with an estimated glomerular filtration rate of 40 mL/min/1.73 m2 or greater and with suitable renal artery anatomy were randomized 2:1 to undergo ultrasound renal denervation or a sham procedure. Patients were to abstain from antihypertensive medications until the 2-month follow-up unless...

We have previously shown that duplex ultrasound is an accurate method of diagnosing renal artery stenosis (93% accuracy compared with angiography in the diagnosis of less than 60% stenosis, 60% to 99% stenosis, or occlusion). With this method we have now serially observed 35 renal arteries wit...
A recent study found that in patients with sepsis, CVP did not correlate with renal venous reflux flatus assessed by Doppler ultrasound, but the severity of renal venous stasis correlated with renal function [93]. In patients with heart failure, baseline renal venous return spectra can be used ...
Ultrasound measurement of brachial artery elasticity prior to hemodialysis access placement: a pilot study. Successful hemodialysis requires reliable vascular access that can deliver adequate blood flow. An arteriovenous fistula is preferred for access because of... AG Sorace,ML Robbin,H Umphrey,... -...
Contrast-enhanced CT showed a solitary large aneurysm in the right artery. Super-selective catheterisation was performed using a microcatheter. The aneurysm was safely and successfully embolised with eight interlocking detachable coils. At 1 year follow-up with colour Doppler ultrasound (US), the ...
Subjects in the study underwent renal denervation using minimum of two 7-second ultrasound sonications delivered bilaterally to the main renal artery; at least one sonication was delivered within accessory arteries of ≥4 mm and ≤8 mm in diameter. The sham control group underwent a renal an...
