Cerebral hypoperfusion in stroke prognosis and brain recovery.
BACKGROUND AND PURPOSE The value of acute cerebral blood flow measurements in stroke prognosis is controversial. No previous study has determined whether acute perfusion deficits independently add to a validated clinical prognostic score. We aimed to compare the value of acute hypoperfusion deficits with a quantitative clinical score in stroke prognosis and to correlate the changes in perfusion...
متن کاملHypoperfusion of an Entire Cerebral Hemisphere – Stroke or Postictal Deficit?
The clinical differential diagnosis between ischemic stroke and postictal deficit is sometimes challenging. If the clinical presentation is inconclusive, perfusion imaging can help to identify stroke patients for thrombolysis therapy. However, also epileptic phenomena may alter cerebral perfusion. Hypoperfusion spreading beyond the borders of cerebrovascular territories is usually considered su...
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 کاملDecompressive Craniectomy in Traumatic Brain Injury:Factors Influencing Prognosis and Outcome
Background and Aim: Decompressive craniectomy can be life-saving for patients with severe traumatic brain injury, but many questions about its ideal application, indications, timing, technique, and even the definition of success of decompressive craniectomy remains unclear. The aim of this study was to assess the factors associated with prognosis and outcome of patients with traumatic brain inj...
متن کاملHypocapnia and cerebral hypoperfusion in orthostatic intolerance.
BACKGROUND AND PURPOSE Orthostatic and other stresses trigger tachycardia associated with symptoms of tremulousness, shortness of breath, dizziness, blurred vision, and, often, syncope. It has been suggested that paradoxical cerebral vasoconstriction during head-up tilt might be present in patients with orthostatic intolerance. We chose to study middle cerebral artery (MCA) blood flow velocity ...
