OBJECTIVES To compare stump pressure (SP), transcranial Doppler (TCD), electroencephalography (EEG) and selective shunting during carotid endarterectomy (CEA) with preoperative positron emission tomography (PET) parameters. MATERIALS AND METHODS Preoperative PET measurements and peroperative neuromonitoring were performed in ten patients undergoing CEA for symptomatic carotid artery disease. ...

Transcranial Doppler (TCD) ultrasound is a noninvasive, safe and cost-effective bedside test for evaluating cerebrovascular circulation in real time. It has been rapidly evolving from a simple noninvasive diagnostic tool to an imaging model with a broad spectrum of clinical applications. TCD can show the spectral flow waveforms, blood flow direction, velocities and intensity in the intracerebra...

A 62 year-old man with known coronary artery disease underwent a three-vessel CABG after a positive exercise tolerance test revealed reversible ischemic changes. Transcranial Doppler ultrasonography (TCD) and transesophageal monitoring (TEE) were used intraoperatively for monitoring of highintensity transient signals (HITS), representing both gaseous and particulate cerebral emboli. Non-pulsati...

BACKGROUND/AIM The contribution of cerebrovascular dysfunction to the manifestation of dementia and cognitive decline in late life is gaining increased attention. We aimed to systematically review evidence for associations between dementia or aging and cerebrovascular function as measured using transcranial Doppler (TCD) examination. METHODS A total of 1,172 articles were retrieved from Psych...

BACKGROUND AND PURPOSE Both transcranial Doppler (TCD) and spiral computed tomography angiography (CTA) are used for noninvasive vascular assessment tools in acute stroke. We aimed to evaluate the diagnostic accuracy of TCD against CTA in patients with acute cerebral ischemia. METHODS Consecutive patients presenting to the Emergency Department with symptoms of acute (<24 hours) cerebral ische...

BACKGROUND AND PURPOSE We sought to identify the use of duplex and transcranial Doppler sonography in the noninvasive diagnosis of vertebral dissection. METHODS Ten patients with a diagnosis of symptomatic vertebral artery dissection confirmed by cerebral angiography were retrospectively analyzed. RESULTS Computed tomographic scanning and magnetic resonance imaging together delineated later...

Contrast-enhanced transcranial Doppler (c-TCD) is a reliable and reproducible method for right-to-left shunt (RLS) detection, with high sensitivity. Monitoring the middle cerebral artery (MCA) is an optimal choice, yet for patients with insufficient temporal bone windows or severe stenosis of carotid arteries, an alternative should be established. The aim of the present study was to further est...
