Renal Duplex Study

Background. Atherosclerotic renovascular disease is associated with an increased risk of cardiovascular disease (CVD) events. This study examines associations between Doppler-derived parameters from the renal artery and renal parenchyma and all-cause mortality and fatal and nonfatal CVD events in a cohort of elderly.

Because these images can also show motion, ultrasound is used for a variety of applications, including studying blood flow through arteries and veins (this part of the exam is known as Doppler). No radiation or injections are used in ultrasound imaging which makes this modality an extremely safe, non-invasive diagnostic.

Associations Between Renal Duplex Parameters and Adverse Cardiovascular Events in the Elderly: A Prospective Cohort Study

Abstract. Our objective was to assess how far the progress in ultrasound devices has increased feasibility and accuracy of Duplex ultrasound (DUS) for the diagnosis of renal artery stenosis (RAS), in a population with high prevalence of atherosclerotic renovascular lesions. Ninety-one hypertensive patients with.

Abstract Renal artery disease is an important cause of both renal failure and hypertension. Duplex ultrasound is a reliable noninvasive method for classifying the severity of renal artery lesions and can be repeated to follow the course of the disease over time. The purpose of this study was to determine the changes in kidney.

Background: Changes in renal artery and renal parenchyma perfusion are believed to correlate with severity of hypertension and worsened renal function, but population-based studies of these associations are not available. This study examines relationships between parameters derived from renal duplex sonography.

Background: The aim of this study was to find pre- dictors to identify patients with hypertension who will not improve after removal of renal artery stenosis (RAS). Methods: Prospective study of patients with unilateral stenosis (60% diameter reduction) and hypertension in. 24-h measurements despite antihypertensive drugs,

How is it done? The renal duplex scan uses an ultrasound beam to measure the velocity of blood passing through the renal arteries. Scanning is performed with the probe placed on the abdomen and lower back. The renal arteries lie at the back of the abdomen and can be obscured by gas in the intestines. This is less of a.

INTRODUCTION: Several published studies have reported differing results of renal duplex ultrasound in detecting significant renal artery stenosis using different Doppler parameters. This study is the largest to date to compare renal duplex ultrasound versus angiography and validate various published Doppler criteria.

Jun 1, 1995. We prospectively entered patients into our study who were being evaluated for possible renal artery stenosis. One hundred and two consecutive patients who had both duplex ultrasound scanning of the renal arteries and renal arteriography were included for analysis. Duplex scanning was done before.
