Cuantificación ultrasonográfica de la estenosis carotídea: recomendaciones de la Sociedad Española de Neurosonología

Neurología, 2013
Resumen: En España se estima que aproximadamente un 28% de los ictus isquémicos son de etiología aterotrombótica y mayoritariamente se deben a una estenosis carotídea.

Stimulated Acoustic Emission Detected by Transcranial Color Doppler Ultrasound

, 2000
Background and Purpose —Experimental and clinical data suggest that insonation of echo-contrast agents with high acoustical power produces disintegration of microbubbles, resulting in a pseudo-Doppler phenomenon called stimulated

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Effect of repeated hot water immersion on cognitive performance, cerebrovascular function, sleep and biomarkers of neurodegeneration in older adults

Experimental Physiology, EarlyView.
Abstract Ageing is associated with cognitive decline and increased risk of developing neurodegenerative disease. Repeated passive heating, using hot water immersion (HWI), may improve cognitive performance via improved cerebral oxygenation, but this is yet to be examined in older adults.

Ultrasound measurement of carotid stenosis: Recommendations from the Spanish Society of Neurosonology

Neurología (English Edition), 2013
In Spain, approximately 28% of ischaemic strokes have an atherothrombotic cause, and most are due to carotid stenosis. Ultrasound is the most commonly used technique for diagnosing carotid stenosis.

Transcranial Doppler Ultrasound as a Guide to Graded Therapeutic Occlusion of the Carotid Artery

, 1990
Although gradual carotid artery occlusion is an accepted and effective treatment for some surgically inaccessible intracranial aneurysms, there are no specific guidelines to determine the optimal amount of carotid artery narrowing at each adjustment. The

Stroke neurovascular responses to exercise: A novel rehabilitation paradigm

Experimental Physiology, EarlyView.
Abstract Stroke is a leading cause of long‐term disability, impacting the cerebrovascular, peripheral vascular and neuromotor systems. Characterising vascular responses to exercise post‐stroke offers valuable insights into the impairments that might influence outcomes during neurorehabilitation.

Predictive value of transcranial doppler ultrasound for cerebral small vessel disease in elderly patients

, 2019
Objective: To investigate the predictive value of transcranial Doppler (TCD) ultrasound for cerebral small vessel disease in elderly patients. Methods: Transcranial Doppler ultrasound and magnetic resonance imaging (MRI) were performed on 184 elderly ...

Cerebral and peripheral haemodynamics at rest and in response to orthostasis during 3 days of simulated heatwave

Experimental Physiology, EarlyView.
Abstract Acute heat stress reduces cerebral haemodynamics and orthostatic tolerance. However, the haemodynamic response to orthostasis during prolonged heat stress typical of heatwaves is unknown. We hypothesised that thermoregulatory‐induced elevations in peripheral haemodynamics during 3 days of simulated heatwave would exacerbate orthostatic‐induced
