BACKGROUND
Acute stroke codes may be activated for anisocoria, but how often these codes lead to a final stroke diagnosis or alteplase treatment is unknown. The purpose of this study was to assess the frequency of anisocoria in stroke codes that ultimately resulted in alteplase
Three hundred and sixty-three cases of cerebral infarction were reviewed: 19 had anisocoria. Eighty percent had the larger pupil contralateral to the hemispheric lesion. The mydriasis was associated with long tract signs in all instances. If the abnormal pupil and long tract signs are not on the
Data on outcomes of critically ill patients requiring mechanical ventilation at the onset of stroke are limited.To assess the hospital and long-term functional outcomes of patients with stroke who require mechanical
A diagnosis based on the presumed mechanism of stroke onset is useful for management strategies in acute ischemic stroke. Ninety-two patients with embolic (cardiac or artery-to-artery) and 107 with non-embolic (thrombotic or hemodynamic) stroke were diagnosed on strict cerebral angiographic criteria
BACKGROUND
Decompressive craniectomy increases the survival rate in cases of malignant middle cerebral artery (MCA) stroke. The imaging and clinical signs that predict a malignant progression of stroke of the MCA are analysed, together with factors associated with a poorer prognosis.
METHODS
The
Coma or stroke with secondary brain malperfusion is usually considered a strong contraindication for emergent surgical treatment of acute aortic dissection. Herein, we present the case of a 30-year-old woman who presented with sudden left hemiplegia and level-7 coma on the Glasgow Coma Scale.
Post-traumatic carotid artery dissection is one of the major causes of ischemic stroke in young patients; its diagnosis remains a challenge for clinicians because of its variable clinical presentation. An otherwise healthy 37-year-old man was referred to the intensive care unit of our faculty for
BACKGROUND
Early neurological deterioration (END) is common after stroke and represents a poor prognostic marker. Manual pupillary assessment to detect END is subjective and has poor interrater reliability. Novel methods of automated pupillometry may be more reliable and accurate. This study aims to
A 40-year-old man developed a Horner syndrome as part of a dorsolateral medullary brainstem infarction. Thirty-six hours after the onset of the stroke, topical instillation of 0.5% apraclonidine produced reversal of anisocoria. This is the first case in which apraclonidine testing has been applied
BACKGROUND
Internal carotid artery dissection (ICAD) is a frequent cause of a stroke in young patients. Risk factors which can lead to dissection include neck injury and diseases of the inner wall of the artery. Common symptoms in ICAD are cervical pain and headache, Horner's syndrome, paralysis of
Brain infarction caused by arterial occlusion of the internal carotid axis sometimes develops Horner syndrome. The purpose of this study is to clarify the characteristics and mechanism of "Horner type" anisocoria, which is one of the symptoms of Horner syndrome, in patients with brain infarction in
Pupil sizes were assessed in 100 patients admitted to an intensive care stroke unit over a 1-year period to determine if differences existed and if anisocoria might help in diagnosis. From life-size photographs the pupil diameters were measured accurately, and clinical information compiled by the
Accurate prediction of malignant brain edema (MBE) after stroke is paramount to facilitate close monitoring and timely surgical intervention. The Enhanced Detection of Edema in Malignant Anterior Circulation Stroke (EDEMA) score was useful to predict potentially lethal malignant edema
Approximately 30% of all stroke patients suffer from post-stroke visual impairment. Hemianopia is the most common symptom, but also neglect, diplopia, reduced visual acuity, ptosis, anisocoria, and nystagmus are frequent. Partial or complete recovery of visual disorders can occur, but many patients
