Early monitoring of cerebral hypoperfusion in rats by laser speckle imaging and functional photoacoustic microscopy.
Because cerebral hypoperfusion brings damage to the brain, prevention of cerebrovascular diseases correlative to hypoperfusion by studying animal models makes great sense. Since complicated cerebrovascular adaptive changes in hypoperfusion could not be revealed only by cerebral blood flow (CBF) velocity imaging, we performed multi-parameter imaging by combining laser speckle imaging and functio...
متن کاملCerebral hypoperfusion during acute Kawasaki disease.
BACKGROUND AND PURPOSE Kawasaki disease is a febrile disease of children notable for systemic vasculitis. There have been many previous reports of various complications, including disorders of the central nervous system. We evaluated cerebral perfusion during the acute stage in patients with Kawasaki disease. METHODS Single-photon emission-computed tomography (SPECT) with 99mTc-hexamethylprop...
متن کاملCerebral hypoperfusion precedes nausea during centrifugation.
INTRODUCTION Nausea and motion sickness are important operational concerns for aviators and astronauts. Understanding the underlying mechanisms associated with motion sickness may lead to new treatments. The goal of this work was to determine if changes in cerebral blood flow precede the development of nausea in subjects susceptible to motion sickness. METHODS Cerebral flow velocity in the mi...
متن کاملOrthostatic Cerebral Hypoperfusion Syndrome
OBJECTIVE Orthostatic dizziness without orthostatic hypotension is common but underlying pathophysiology is poorly understood. This study describes orthostatic cerebral hypoperfusion syndrome (OCHOs). OCHOs is defined by (1) abnormal orthostatic drop of cerebral blood flow velocity (CBFv) during the tilt test and (2) absence of orthostatic hypotension, arrhythmia, vascular abnormalities, or oth...
متن کاملRegional cerebral oxygen saturation is a sensitive marker of cerebral hypoperfusion during orthotopic liver transplantation.
Neurological complications contribute significantly to morbidity and mortality of patients after orthotopic liver transplantation (OLT). One possible cause of postoperative neurological complications is cerebral ischemia during the surgical procedure. In this study, we investigated the relationship between intraoperative changes in regional cerebral oxygen saturation (rSo(2)) and postoperative ...
