Uso do ultra-som dúplex Doppler no diagnóstico de shunt portossistêmico em gatos Portosystemic shunt diagnosis using duplex Doppler ultrasonography in cats

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2008
Realizaram-se exames ultra-sonográficos dúplex-Doppler abdominal em dois gatos que apresentavam sinais clínicos de encefalopatia hepática. Os principais achados ultra-sonográficos foram: identificação de um vaso anômalo tortuoso desviando o fluxo portal,

Cerebrovascular flow‐mediated dilation in humans: Methodological challenges, physiological interpretation and future integrations

Experimental Physiology, EarlyView.
Abstract Arterial shear‐mediated vasodilation is a well‐established measure of endothelial function and serves as a critical biomarker for cardiovascular disease risk. Endothelial function can be measured using a variety of experimental methodologies; however, the most widely adopted technique is ultrasound‐based flow‐mediated dilation (FMD), in which ...

Vascular system doppler diagnostic [PDF]

Serbian Journal of Anesthesia and Intensive Therapy, 2019
Vascular diseases are the leading cause of death in Serbia and disability in people over 50 years of age. Ultrasonography examination is quick, painless, safe and comfortable for patients, and for the public health care system inexpensive and accurate ...

Whole‐body hot water immersion effect on cerebral haemodynamics and subsequent cerebrovascular reactivity to carbon dioxide

Experimental Physiology, EarlyView.
Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...

Duplex Ultrasound Scan Can Prevent Leg Amputation in Severe Postthrombotic Syndrome: A Case Report

Case Reports in Vascular Medicine
Conclusion: Duplex provided vital information for surgical planning, which venogram was unable to offer. This is an imaging pitfall that is important to be aware of in patients presenting with recurrent venous disease.

Effects of age, gender, and hemisphere on cerebrovascular hemodynamics in children and young adults: Developmental scores and machine learning classifiers.

PLoS ONE, 2022
A constant blood supply to the brain is required for mental function. Research with Doppler ultrasonography has important clinical value and burgeoning potential with machine learning applications in studies predicting gestational age and vascular aging.

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Evaluation of effects of Extracorporeal Shock Wave Lithotripsy on renal vasculature with Doppler ultrasonography

, 2013
In this prospective study, we aimed to demonstrate the effects of Extracorporeal Shock Wave Lithotripsy (ESWL) on renal blood flow in patients treated for renal/ ureteral stones.The study group comprised 41 patients (26 males, 15 females, aged between 18-
