Analysis of CO2 vasomotor reactivity and vessel diameter changes by simultaneous venous and arterial Doppler recordings.
BACKGROUND AND PURPOSE The use of flow velocity changes in the middle cerebral artery (MCA) measured by Doppler techniques as an index of corresponding cerebral blood flow (CBF) changes is based on the assumption that the insonated arterial diameter remains stable. The postulate of unchanging vessel calibers during CBF changes, however, is still under debate. We performed simultaneous measureme...
متن کاملAssessment of cerebral autoregulation dynamics from simultaneous arterial and venous transcranial Doppler recordings in humans.
We investigated the validity of transcranial Doppler recordings for the analysis of dynamic responses of cerebral autoregulation. We found no significant differences in percentage changes among maximal (centerline) blood flow velocity, cross-sectional mean blood flow velocity, and signal power-estimated blood flow during 24-mm Hg stepwise changes in arterial blood pressure. We investigated bloo...

Background and Aim: Thrombosis of the cerebral veins and sinuses is a distinct cerebrovascular disorder that most often affects young adults and children. Failure in brain autonomic activity could be provoked because of damage to energy-dependent cellular membrane pumps resulting from cytotoxic edema and cerebral ischemia. Measurement of vasomotor reactivity (VMR) through Trans-cranial Dopp...
