Resultados do estudo do Doppler transcraniano em crianças e adolescentes portadores de doença falciforme e correlação entre a velocidade média máxima e características hematológicas: um estudo transversal analítico [PDF]

, 2011
CONTEXT AND OBJECTIVE: Transcranial Doppler (TCD) detects stroke risk among children with sickle cell anemia (SCA). Our aim was to evaluate TCD findings in patients with different sickle cell disease (SCD) genotypes and correlate the time-averaged ...

Transcranial doppler ultrasonography should it be the first choice for persistent foramen ovale screening? [PDF]

, 2014
BACKGROUND: Persistent foramen ovale (PFO) is considered a cause of cryptogenic stroke and a risk factor for neurological events in young patients. The reference standard for identifying a PFO is contrast-enhanced transesophageal echocardiography (TEE ...

A noninvasive estimation of cerebral perfusion pressure using critical closing pressure. [PDF]

, 2015
OBJECT: Cerebral blood flow is associated with cerebral perfusion pressure (CPP), which is clinically monitored through arterial blood pressure (ABP) and invasive measurements of intracranial pressure (ICP). Based on critical closing pressure (CrCP), the

Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

Annals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Impaired Cerebral Haemodynamics in Vascular Depression: Insights From Transcranial Doppler Ultrasonography

Frontiers in Psychiatry, 2018
Introduction: Late-life depression is a well-known risk factor for future dementia. Increasing evidences also show a link between cerebral hypoperfusion and neurodegeneration, although data on Transcranial Doppler ultrasonography (TCD)-derived measures ...

Results of an international survey on the investigation and endovascular management of cerebral vasospasm and delayed cerebral ischemia [PDF]

, 2015
Background: Delayed cerebral ischemia (DCI) is a major cause of morbidity and mortality in aneurysmal subarachnoid hemorrhage. Endovascular management of this condition offers a new hope in preventing adverse outcome; however, a uniform standard of ...

Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

Journal of Clinical Ultrasound, EarlyView.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Patent foramen ovale and thromboembolic complications [PDF]

, 2010
The foramen ovale, an atrial septal defect which is essential in the fetal circulation, remains patent through adulthood in approximately 25% of the general population and so it represents the most common persistent abnormality of fetal origin.

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...
