Clinical Trials [2525 Associated Clinical Trials listed on BioPortfolio]

Transcranial Doppler Ultrasound in Critically Ill Patients With Cardiovascular Comorbidities

Transcranial Doppler ultrasound is bedside tool use to assess cerebral blood perfusion in critically ill patients. We sought to conduct a prospective, single centre study aiming to determi...

Reproducibility Study of Transcranial Doppler

Hardening of the neck vessels (carotid arteries) caused by fatty deposits called 'plaques' is a common cause of strokes. Over time plaques can burst or may lead to a severe narrowing (sten...

Mechanisms of Ischemic Stroke in Cancer Patients

The purpose of this study is to better understand the causes of stroke in people with cancer. Active cancer increases the risk of stroke. We do not know exactly why this occurs but one pos...

Brainstem Grey Matter and Cerebral Autoregulation in Migraine With Aura.

Migraine with aura (MA) is an independent risk factor for stroke and is associated with silent brain infracts and T2 white matter hyperintensities on MRI. Previous studies using Transcrani...

Evaluation of Transcranial Doppler Vasoconstrictor Vasoreactivity During General Anesthesia in Hypertensive Patients

During a general anesthesia, people over 65 years old and hypertensive, have a modification of the vasoreactivity and their cerebral blood flow under vasoconstrictor such as norepinephrine...

A comparison of transcranial Doppler and magnetic resonance imaging for long term changes in middle cerebral artery stenosis.

Intracranial arterial stenosis may progress or regress, of which the diagnosis is important to predict the risk of stroke or to evaluate the response of treatment. Transcranial Doppler (TCD) seems to ...

Transcranial Doppler Evaluation in Takayasu Arteritis With Oculo-Cerebrovascular Complications.

Takayasu arteritis is a large-vessel vasculitis that may cause oculo-cerebral ischemia. We report a patient with visual loss as initial manifestation, and discuss transcranial Doppler (TCD) findings b...

Prediction of functional outcome using the novel asymmetric middle cerebral artery index in cryptogenic stroke patients.

Etiology is unknown in approximately one-quarter of stroke patients after evaluation, which is termed cryptogenic stroke (CS). The prognosis of CS patients is largely undetermined. We created a novel ...

Transcranial Doppler ultrasound in vascular cognitive impairment-no dementia.

Although cerebral white matter lesions (WMLs) are considered as a risk factor for vascular dementia, data on their impact on cerebral hemodynamics are scarce. We test and compare transcranial Doppler ...

Doppler sonography enhances rtPA-induced fibrinolysis in an in vitro clot model of spontaneous intracerebral hemorrhages.

Transcranial Doppler (TCD) was shown to enhance intravascular fibrinolysis by rtPA in ischemic stroke. Studies revealed that catheter-based administration of rtPA induces lysis of intracerebral hemorr...

Medical and Biotech [MESH] Definitions

A non-invasive technique using ultrasound for the measurement of cerebrovascular hemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum.

Ultrasonography applying the Doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the Doppler shift frequency.

Echocardiography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image.

Echocardiography applying the Doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return.
