Background and Purpose: Ischemic episodes distal to an internal carotid artery occlusion are common. We undertook this study to look for evidence of transhemispheric passage of embolic material in this patient category as a mechanism for embolic events. Methods: Seven symptomatic patients with unilateral internal carotid artery occlusion and contralateral stenosis were examined by transcranial ...

ischemic stroke accounts for about 87 percent of all cases. it occurs as a result of an obstruction within a vessel of the brain and sudden loss of blood circulation to the corresponding area resulting in the loss of brain function. it is caused by thrombotic or embolic occlusion of an artery and is more common than hemorrhagic stroke. we know that most of the injuries after an acute ischemic s...

background: although the risk factors of ischemic strokes are well defined, there is slight information about their relations with the etiologies of ischemic strokes. this study investigated the distribution of ischemic stroke risk factors and their connections to diverse etiologies of cerebrovascular attack (cva) and specific ischemic regions of brain. methods: in this cross sectional study , ...

Since tako-tsubo syndrome (TS) frequently appears soon after stroke (usually stroke involving the insular cortex), it is believed to be a consequence rather than a cause of stroke. Herein, we describe a 70-year-old woman presenting with a left middle cerebral artery stroke (involving the insular cortex) who developed a further contralateral ischemic stroke with concomitant detection of a transi...

See related article, pages 2379–2383. Unlike in acute myocardial infarction, the underlying pathophysiological mechanism of vascular arterial occlusion in acute stroke is heterogeneous. Composition of cerebral embolic material may vary, depending on specific endothelial and flow conditions of the embolic source. Old, platelet-rich, and well-organized thrombi formed under flow conditions have be...

BACKGROUND AND PURPOSE The aims of this study were to verify that tissue-type plasminogen activator given either 1 or 2 hours after experimental embolic stroke in rabbits diminishes the volume of resulting ischemic brain and to ascertain the effect of the simultaneous administration of heparin. METHODS We embolized the middle cerebral artery of rabbits by injecting performed autologous arteri...

Introduction: Arterial hypertension is one of the causes of stroke, and as one of the vasculotoxic conditions intensifies ischemic stroke complications. The aim of the present study was to analyze the effects of short-term cerebral hypertension on ischemia/reperfusion injury and pathogenesis of ischemic stroke. Methods: The experiments were performed on three groups of rats (N=36) Sham, cont...

BACKGROUND AND PURPOSE Discharge ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification) codes have been used to identify patients with acute stroke for epidemiological, quality of care, and cost studies. The aim of this study was to determine if the accuracy of the primary ICD-9-CM codes for ischemic stroke is improved by modifier codes and how specific codes r...

BACKGROUND Impact of high level of uric acid on stroke is still controversial. We conducted this study to investigate the relationship between acute ischemic non-embolic stroke and serum levels of uric acid. METHODS This was a case-control study on patients with acute ischemic non-embolic stroke in Rafsanjan, Iran. The control group consisted of normal persons who were similar to the case gro...
