Middle cerebral artery function after stroke: the threshold duration of reperfusion for myogenic activity.
BACKGROUND AND PURPOSE Myogenic activity of the cerebral arteries is an important contributor to autoregulation of cerebral blood flow. Previous studies have demonstrated that increasing periods of ischemia diminished the amount of myogenic tone in cerebral arteries. In the present study, we investigated the effect of different periods of postischemic reperfusion on the myogenic behavior of mid...
متن کاملPrognostic value of doppler ultrasound findings in patients with middle cerebral artery Ischemic stroke
Introduction: There is still no finding available that can show the malignant clinical course in patients with middle cerebral artery stroke. The aim of this study was to compare Doppler ultrasound findings in patients with malignant and non-malignant middle cerebral artery stroke in order to obtain its prognostic value in detecting malignant course. Method:</stro...
متن کاملCerebral infarction after middle cerebral artery occlusion in progenies of spontaneously stroke-prone and normal rats.
A differential outcome results from rapid middle cerebral artery (MCA) occlusion in young normotensive Wistar (NW) rats as compared to the spontaneously hypertensive stroke-prone (SHRSP) rat. The SHRSP invariably infarcts; the NW usually does not. To determine if segregation at a single autosomal locus explains the difference between strains, a NW male was crossed with several SHRSP females to ...
متن کاملHyperdense middle cerebral artery sign after trauma.
© 2014 American Osteopathic Association A 56-year-old man presented to the emergency department after a highwayspeed, single-vehicle motor vehicle accident. Physical examination revealed no evidence of head trauma but was notable for a Glasgow Coma Scale score of 6, with the patient exhibiting a withdrawal response to pain on his left side. Computed tomography findings included a hyperdense mid...
متن کاملUltrasound microbubble destruction imaging in acute middle cerebral artery stroke.
BACKGROUND AND PURPOSE Cerebral perfusion imaging in acute stroke assists in determining the subtype and the severity of ischemia. Recent studies in perfusion models and in healthy volunteers have shown that ultrasound perfusion imaging based on microbubble destruction can be used to assess tissue perfusion. We applied ultrasound microbubble destruction imaging (MDI) to identify perfusion defic...
