Brain death (BD) diagnosis is the clinical assessment of the irreversible loss of function of the entire brain, including the brainstem. Transcranial Doppler (TCD) examination is used in several countries as a confirmatory test to assess cerebral circulatory arrest (CCA), but is not feasible in patients with absent temporal bone windows. TCD is highly specific, but less sensitive because of fal...

BACKGROUND AND PURPOSE The present study investigated the influence of the antiplatelet agent acetylsalicylic acid (ASA) on cerebral microembolism as detected by transcranial Doppler sonography (TCD). METHODS Nine patients with recent transient ischemic attack or minor stroke of arterial origin were investigated. Eight had not received an antiplatelet or anticoagulant medication before TCD, a...

Background. If detected in time, delayed cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH) may be treated by balloon angioplasty or chemical vasospasmolysis in order to enhance cerebral blood flow (CBF) and protect the brain from ischemic damage. This study was conceived to compare the diagnostic accuracy of detailed neurological examination, Transcranial Doppler Sonography (TCD...

Transcranial Doppler sonography shows potential as a noninvasive technique for long-term follow-up of treated intracranial saccular aneurysms. This technical note describes a color Doppler artifact related to microcoil architecture that might represent a potential pitfall in transcranial Doppler sonographic evaluation of aneurysmal cavity thrombosis, since it may be wrongly interpreted as resid...

The daily increasing number of cervical whiplash injuries presents ever-greater requirement for vertebrobasilar diagnostics. A cervical spine injury, which is quite frequent injury, may occur during a fall, or industrial, traffic, sport or war injury. Transcranial Doppler (TCD) sonography with Transcan 3-D EME device and 2 MHz probe was used for the assessment of vertebrobasilar circulation in ...

Intravenous tissue plasminogen activator (TPA) improves patient chances to recover from stroke by inducing mostly partial recanalization of large intracranial thrombi. TPA activity can be enhanced with ultrasound including 2 MHz transcranial Doppler (TCD). TCD identifies residual blood flow signals around thrombi, and, by delivering mechanical pressure waves, exposes more thrombus surface to ci...

Patent foramen ovale (PFO) is a remnant of the fetal circulation exist in 20% of the general population. The purpose of our study was to compare of transthoracic echocardiography (TTE) and contrast-transcranial Doppler sonography (c-TCD) in the diagnosis and quantification of PFO with or without the Valsalva maneuver (VM).We studied 106 patients with a high clinical suspicion for PFO prospectiv...

Cerebral vasospasm and delayed cerebral ischemia are common complications associated with subarachnoid hemorrhage (SAH) outcomes. Various modalities can be used to evaluate detect after SAH. Transcranial Doppler (TCD) ultrasonography as an appropriate bedside dynamic monitoring tool screen for the presence progression of in patients This article briefly reviewed severity SAH pathophysiology vas...
