Transcranial Doppler detection of vertebrobasilar vasospasm following subarachnoid hemorrhage.
, 1994 BACKGROUND AND PURPOSE: Transcranial Doppler sonography is of established value in the detection and monitoring of middle cerebral artery vasospasm. Little information exists on the utility of transcranial Doppler for detection of posterior circulation ...

Experimental Physiology, EarlyView.Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

Journal of Diagnostic Medical Sonography, 2018 The correlation between cryptogenic stroke and patent foramen ovale is high in young patients. Currently, transesophageal echocardiography is the gold standard for detection. However, it is invasive and limits Valsalva maneuvers. This article reviews the

Cerebral haemodynamic responses to inspiratory muscle work
Experimental Physiology, EarlyView.Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Hemodynamic changes of severe carotid atheromatosis pre and post endarterectomy in the case of a coronary patient with ischemic stroke [PDF]
Romanian Journal of Neurology, 2013 Nearly 25%-30% of ischemic strokes are due to atherosclerosis of the carotid bifurcation. Cerebrovascular reactivity (CVR) is an indicator for testing hemodynamic status of cerebral circulation.

Critical Care Medicine, 2017 Objectives: To assess whether microemboli burden, assessed noninvasively by bedside transcranial Doppler ultrasonography, correlates with risk of subsequent stroke greater than 24 hours after hospital arrival among patients with blunt cerebrovascular ...

Experimental Physiology, EarlyView.Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Reproducibility of Transcranial Doppler ultrasound in the middle cerebral artery
Cardiovascular Ultrasound, 2018 Background Transcranial Doppler ultrasound remains the only imaging modality that is capable of real-time measurements of blood flow velocity and microembolic signals in the cerebral circulation.
