Short Communication Orthostatic Transient Ischemic Attacks: A Symptom of Large Vessel Occlusion
نویسنده
چکیده
TRANSIENT CEREBRAL ISCHEMIC ATTACKS may be focal or generalized (syncope). The latter are usually caused by a fall in systemic blood pressure, often precipitated by standing. Focal transient ischemic attacks (TIA) however, are rarely associated with hypotensive episodes' 2 and even more rarely are precipitated by standing. A case of orthostatic TIA is presented and previous cases from the literature summarized.

Orthostatic transient ischemic attacks: a symptom of large vessel occlusion.
Orthostatic transient ischemic attacks (TIA) are very much rarer than orthostatic generalized cerebral ischemia (syncope). A case is described and previous reports reviewed. Orthostatic TIA appears to occur only with large vessel occlusion. In these patients, collateral blood supply is marginal and unable to support normal postural autoregulation.
متن کاملCerebral ischemic attack caused by postprandial hypotension.
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...
متن کاملPrimary orthostatic cerebral ischaemia.
four patients with "primary orthostatic cerebral ischaemia" are described. They complained of dizziness, light-headedness or syncope on standing. None had a significant fall in his systemic blood pressure on assuming the erect posture. Each had bruits over the major neck vessels or absent pulses. Angiography showed widespread narrowing or occlusion of the cervical blood vessels which supply the...
متن کاملNeuroprotective Effect of Paroxetine on Memory Deficit Induced by Cerebral Ischemia after Transient Bilateral Occlusion of Common Carotid Arteries in Rat
Aims:Memory deficit is the most visible symptom of cerebral ischemia. The hippocampus is sensitive against cerebral ischemia. Oxidative stress and inflammation are involved in the pathological process after cerebral ischemic injury. Paroxetine has anti-oxidative and anti-inflammatory effects. In this study the effect of paroxetine on memory deficit after cerebral ischemia was investigated. Meth...
متن کاملSignificance of large vessel intracranial occlusion causing acute ischemic stroke and TIA.
BACKGROUND AND PURPOSE Acute ischemic stroke due to large vessel occlusion (LVO)-vertebral, basilar, carotid terminus, middle and anterior cerebral arteries-likely portends a worse prognosis than stroke unassociated with LVO. Because little prospective angiographic data have been reported on a cohort of unselected patients with stroke and with transient ischemic attack, the clinical impact of L...
