Background and Purpose—Transcranial color-coded duplex sonography (TCCS) of
intracranial veins and sinuses in adults is a new, emerging application of ultrasonographic …

It is now well recognized that low cerebral blood flow (and cerebral perfusion pressure
(CPP)) is associated with poor outcome after traumatic brain injury. What is less clear is …

To determine the dependence of cerebral blood flow (CBF) on arterial pressure over
prolonged time periods, we measured beat-to-beat changes in mean CBF velocity in the …

Object. The aim of this study was to analyze how the main values extrapolated from the
transcranial Doppler (TCD) waveform (systolic, mean, and diastolic velocity; velocity peak-to …

OBJECTIVE: This study was undertaken to evaluate the effect of acute moderate
hyperventilation on cerebral autoregulation in head-injured patients. METHODS: Dynamic …

Background and Purpose—Dynamic methods of measuring cerebral autoregulation have
become an accepted alternative to static evaluation. This article aims to describe a set of …

Object. The purpose of this study was to evaluate the extent and timing of impairment of
cerebral pressure autoregulation after severe head injury. Methods. In a prospective study of …

Cerebral blood flow responses to transient blood pressure challenges are frequently
attributed to cerebral autoregulation (CA), yet accumulating evidence indicates vascular …

Object. The effect of increased intracranial pressure (ICP) on cerebral venous blood flow has
been the subject of very few clinical and experimental studies. The authors assessed the …

Aim To compare maternal cerebral hemodynamics, as assessed by transcranial Doppler
studies, with the clinical and radiological findings in different types of pregnancy‐related …
