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 determine whether chronic vascular diseases may be a confounder in transcranial Doppler ultrasound assessment in critically ill patients.
Intracranial hypertension is associated with altered transcranial doppler parameters measured in the middle cerebral artery such as decreasing diastolic velocity and increasing pulsatility index with higher intracranial pressure (ICP). Chronic vascular diseases in modifying arterial resistance may interfere with transcranial Doppler ultrasound assessment mimicking intracranial hypertension profile.
The aim of this prospective, single centre study enrolling critically ill patients without any acute neurological disease is to to determine the pattern of transcranial Doppler ultrasound variables amongst patients with and without chronic vascular diseases.

The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and TRANSCRANIAL MAGNETIC STIMULATION. It is often used for monitoring during neurosurgery.
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.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
Pulmonary arterial hypertension (PAH) is a chronic, life-threatening disorder characterized by abnormally high blood pressure in the arteries between the heart and lungs of affected individuals. Symptoms can range from mild breathles...
