The association between carotid artery disease, transient ischemic attack (TIA), and stroke has been recognized for many years. There still appears to be some controversy over the accuracy of lesion detection with intraarterial digital subtraction angiography (IADSA) as compared with film screen technique. We describe a prospective study that took place over a period of nearly 4 years with 30 c...

introduction: aphasia is a common manifestation of stroke and evaluation of relationships of aphasia and brain topography could lead to better understanding of cognitive neurophysiology. methods: 100 stroke patients with aphasia admitted in valie-asr hospital, khorasan since april 2003 were enrolled in this prospective cross-sectional study. diagnosis of stroke and aphasia was made by a neurolo...

background and purpose: cancer and cerebrovascular accidents (cva) are two most common causes of mortality and morbidity in the elderly. patients with brain tumor can be highly affected by postsurgical stroke. cva may be the first manifestation in these patients . therefore, we aimed to assess the epidemiological factors affecting cva after brain surgery. methods: in this cross-sectional study ...

background: the aim of the present study was to determine the prevalence and prognosis of cerebrovascular accident(cva) and its subtypes among iranian patients with systemic lupus erythematosus (sle). methods: in a cross-sectional study, medical records of 575 sle patients were reviewed. the patients developing cva in their course of disease were extracted. in these patients, data about demogra...

myelodysplastic syndromes (mds) are a group of hematological disorders ranging from chronic refractory anemia to leukemia. there are some reports about association of mds with autoimmune disorders and vasculitis. in this study we describe a patient with mds and vasculitis presenting with central nervous system (cns) involvement. a clinical response to immunosuppressive therapy was also observed...

Among the various manifestations of cerebrovascular disease none is more important than the phenomenon of transient ischaemic attacks. This importance stems from the fact that, though these short-lived disturbances of neurological function may continue for years without apparent detriment to the patient, they often give warning of an impending stroke. Most commonly they are associated with athe...

BACKGROUND AND PURPOSE Although cerebral circulation time (CCT) is one of the main parameters in cerebral blood flow measurements, its clinical significance is controversial. To assess the importance of CCT by using a nondiffusible indicator, we studied the relationship between angiographic CCT and cerebrovascular reserve. METHODS Twenty-eight patients, each with a unilateral occlusive lesion...
