Background: Cerebral hyperperfusion syndrome (CHS) is a failure of autoregulation after revascularization procedure. It has rarely been reported in patients with no pre-existing cerebral hypoperfusion. Case Report: We present rare case patient who underwent stent graft implantation to treat postirradiated carotid blowout syndrome. The developed hypertension, focal neurological deficit, and seiz...

BACKGROUND AND PURPOSE Although blood pressure reduction has been postulated to result in a fall in cerebral perfusion pressure in patients with intracerebral hemorrhage, the latter is rarely measured. We assessed regional cerebral perfusion pressure in patients with intracerebral hemorrhage by using CT perfusion source data. MATERIALS AND METHODS Patients with acute primary intracerebral hem...

Brain perfusion for adequate cerebral protection has changed over the years. The limitations of the time during total circulatory arrest with deep hypotermia, the inefficient cerebral metabolism during retrograde perfusion and special care to prevent cerebral embolism during antegrade perfusion have resulted in the development of different methods of cerebral protection during the evolution of ...

Background: Ultrasound (US) has been used in neuroprotection after cerebral ischemia, however the mechanism of action remains unclearly. We have previously shown the protective effect of ultrasound on infarction volume and brain edema in ischemic brain injured at normothermic condition. Ultrasound may also amplify the effect of fibrinolytic medications in thrombolysis process .We have also show...

OBJECTIVE Cerebral perfusion pressure<40 mm Hg following pediatric traumatic brain injury has been associated with increased mortality independent of age, and current guidelines recommend maintaining cerebral perfusion pressure between 40 mm Hg-60 mm Hg. Although adult traumatic brain injury studies have observed an increased risk of complications associated with targeting a cerebral perfusion ...
