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...
Other methods, such as the ratio of the PSV in the aorta to the PSV in the renal artery (RAR) or indirect criteria, such as side to side differences in RI (dRI) or AT can be additionally used to improve accuracy. Contrast-enhanced ultrasound improves accuracy by means of echo contrast ...
If either duplex ultrasound or a contrast CT scan documents blunt occlusion of a renal artery, the surgeon must decide on the need for operation, endovascular intervention, or observation. Intuitively, the time interval from the episode of trauma to restoration of arterial flow would appear to be...
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...

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...

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,... -...
Ultrasound microbubble contrast agent can be injected via peripheral vein through the pulmonary circulation to finally reach the target organ or tissue, to achieve tissue echo enhancement, and the contrast agent can be observed in the tissue of the area of interest. Evaluation of renal ...
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...
