Abnormal Hemispheric Blood Flow and Metabolism in Cerebrovascular Disease. I. Disordered Patterns of Hemispheric Metabolism • Hemispheric blood flow (HBF) and metabolism were studied in 46 patients with various types and stages of ischemic cerebrovascular disease and were found to be abnormal in all patients, including those with transient ischemic attacks. Bilateral depression of HBF and metab...

BACKGROUND AND PURPOSE Transcatheter closure of patent foramen ovale (PFO) has been reported to improve migraine in patients with cerebrovascular disorders in noncontrolled studies. The aim of the study was to compare the course of migraine assessed prospectively over a 12-month period in symptomatic (for cerebrovascular disease) and asymptomatic patients undergoing PFO closure and in patients ...

Ischemia or hemorrhage are the byproducts of cerebrovascular disease, manifest as sudden, focal neurological deficits related to specific vascular territories of the central nervous system. Impairment or loss of consciousness is a global deficit, which rarely is caused by simultaneous, extensive or multiple hemorrhages or ischemic infarctions, and is more commonly due to other causes such as ce...

A prospective study of 1,517 consecutive cerebral angiographic examinations is reported. The incidence of all complications was 8.5%, and the incidence of all neurologic complications was 2.6%. The overall incidence of permanent neurologic deficit was 0.33%. The incidence of permanent neurologic deficit in patients referred for evaluation of symptomatic cerebrovascular disease was 0.63%. Older ...

Two young adults with lupus anticoagulant had multiple attacks of cerebrovascular ischemia in different arterial territories. Cerebral angiography was normal. One patient had a new episode during anticoagulant therapy, but has remained asymptomatic on antiplatelet treatment. In the other, further events occurred during treatment with platelet-inhibiting drugs, but there have been no recurrences...

BACKGROUND Food ingestion sometimes induces systemic hypotension (postprandial hypotension). Although the possibility of stroke occurring postprandially has been suggested, no cases have been reported until now. CASE DESCRIPTION A 78-year-old man experienced repeated transient ischemic attacks after almost every ingestion of food and showed orthostatic and postprandial hypotension. An angiogr...

We compared clinical and angiographic features of 26 white and 45 black patients with symptomatic occlusive cerebrovascular disease. White patients had more transient ischemic attacks, carotid bruits, and more severe occlusive disease of the internal carotid artery origin. Blacks had more severe disease of the middle cerebral artery stem and supraclinoid internal carotid arteries. Differences w...

background: stroke is the main cause of physical disability and the second leading cause of death worldwide. two-thirds of all strokes occur in the developing countries. despite being preventable, stroke is increasingly becoming a major health issue in these countries. the aim of this study was to evaluate the epidemiology of stroke in shiraz, iran, one of the main referral centers in the south...

oxygen therapy might increase damaged tissue oxygenation, turn on the aerobic pathway, and save neurons from death and could improve clinical outcome of the patients with stroke and head trauma. hyperbaric oxygen therapy is accompanied by some unfavorable effects. results of normobaric oxygen therapy on clinical outcomes of patients with stroke were controversial up till now.  this study was th...
