frequency of common etiologies of adult onset epilepsy is different in various studies. the aim of this study is to evaluate the frequency of common ‎etiologies of late adult onset epilepsies. ‎ all patients referred to razi and imam khomeini hospitals ‎in the year 2003 with at least two seizure attacks beginning after age of 50 were evaluated. in the majority of cases neuroimaging, electroence...

Cerebral angiograms were performed in 14 children with sickle cell disease and clinical findings of cerebral infarction. The angiogram was normal in four patients. Ten patients had abnormalities in the carotid artery or its branches. The internal carotid artery was stenosed or occluded usually with bilateral disease. The anterior and middle cerebral arteries were involved in nine patients and b...

We report a patient with three cerebrovascular events involving the posterior circulation, one of which occurred in conjunction with central retinal artery occlusion. The patient had constitutional findings but had a normal cardiac examination, negative echocardiogram, and negative blood cultures. Angiography on two separate occasions revealed left vertebral artery occlusion. Repeat echocardiog...

Using clinical presentation, angiography, computed tomography, and nuclear magnetic resonance imaging, 7 patients were identified who had strictly unilateral hemispheric infarction and unilateral cerebrovascular disease. In 6, cerebral blood flow measured by fluorine-18-fluoromethane inhalation and positron emission tomography was reduced in the contralateral hemisphere (p less than 0.05). Mult...

In a retrospective study, the clinical and angiographic results were evaluated of 100 consecutive carotid endarterectomies, carried out in 90 patients over the period 1977 to 1983. There was no operation-associated mortality; the perioperative morbidity was 5%. Angiography, carried out, on average, 4.2 months postoperatively, revealed complete occlusion of the operated carotid artery in 16 case...

The applications of digital subtraction angiography (DSA) in neurologic diagnosis have been evolving as clinical experience with this technology accumulates. Initial enthusiasm with the intravenous contrast material injections has been tempered by often equivocal results. Intravenous DSA (IV-DSA) is still an accurate screening technique for extracranial carotid atherosclerosis, comparable to du...

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...

Cerebrovascular disease is increasing rapidly because of its high morbidity and mortality, which a serious threat to human health. For the early diagnosis treatment diseases, CT vascular noise combined with high-resolution magnetic resonance angiography in acute cerebral apoplexy adopted. 150 patients ischemic stroke were selected, admitted Department Radiology, Huizhou Central People’s Hospita...
