Value of Doppler parameters in the diagnosis of renal artery stenosis

Journal of Vascular Surgery

Abstract

Our purpose was to assess the accuracy and optimal threshold values of the Doppler parameters of the renal arteries and parenchyma for detecting renal artery stenosis (RAS) greater than 60% and occlusion. Renal duplex ultrasonography and standard angiographic studies of the renal arteries were performed in 78 patients for comparative analysis. Three degrees of RAS were considered: less than 60%, greater than 60%, and occlusion. The following parameters of the Doppler wave were measured in the signal obtained from the main renal artery and interlobar arteries: peak systolic velocity (PSV), end-diastolic velocity, peripheral resistance index, acceleration time, acceleration index, and renal/aortic ratio (RAR). Logistic regression analysis identified the PSV in the renal artery as the best parameter to differentiate RAS less than 60% from RAS greater than 60%. Only when this parameter was excluded were the RAR and end-diastolic velocity in the renal artery the variables accepted as the best predictors. Receiver-operator curve analysis revealed a PSV in the main renal artery greater than 198 cm/sec and RAR greater than 3.3 as the best cutoff points for detecting RAS greater than 60%. A PSV above this threshold provided 87.3% sensit...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
