Using Doppler ultrasonography, we evaluated the frequency and severity of carotid artery stenosis in 261 patients with carotid ischemic strokes, 813 patients with carotid transient ischemic attacks, 500 patients with asymptomatic neck bruits, and 500 controls. Most patients with strokes and transient ischemic attacks had no associated carotid artery disease (55% and 64%, respectively), and such...

dissection of the internal carotid artery (ica) is a rare condition that accounts for a significant proportion of ischemic strokes in young adults. iatrogenic dissection as a complication of neurointerventional procedures is a traumatic dissection which has been reported relatively rare in the literature. in this report, a case of dissection of the ica is reported that was caused by repetitive ...

Ischemic stroke is an important cause of morbidity and mortality when untreated. Identifying atrial fibrillation is important because atrial fibrillation ischemic related strokes are associated with an increased risk of disability and death compared with strokes of other etiologies and tend to recur without anticoagulation. However, atrial fibrillation detection can be difficult when it is asym...

BACKGROUND AND PURPOSE Acute ischemic stroke patients are infrequently treated with recombinant tissue plasminogen activator (rtPA). We present unique population-based data regarding the eligibility of ischemic stroke patients for rtPA treatment. METHODS All ischemic strokes presenting to an emergency department (ED) within a biracial population of 1.3 million were identified. The patient was...

BACKGROUND AND PURPOSE Higher proportions of hemorrhagic stroke and lacunar infarction were reported in rural Japan compared with those in Western countries. We examined the relative proportions of stroke subtypes in an urban Japanese city where westernized lifestyles are more common than in rural areas. METHODS Stroke registration was performed in 1992, 1997, and 2002 for residents > or =40 ...

Broadly, strokes are classified into two main types-ischemic and hemorrhagic. Ischemic stroke (IS) is characterized by blockage in blood flow to a focal area of the brain, until hemorrhagic stroke is caused by bleeding into the brain. Acute IS is more common than hemorrhagic stroke. Although according the previous literature data about 80% of strokes were ischemic, the retrospective review from...

Background and Purpose—About 60% to 80% of all ischemic strokes can be attributed to increasing blood pressure, blood cholesterol, cigarette smoking, carotid stenosis, and diabetes mellitus (atherosclerotic ischemic stroke), and atrial fibrillation and valvular heart disease (cardiogenic ischemic stroke). The aim of this review was to examine the potential role of other risk factors in the etio...

The authors report an autopsy case with repeated transient ischemic attacks and subsequent strokes demonstrating evidence of artery-to-artery embolism from thrombi generated in the stenotic middle cerebral artery to the distal cortical branches. This case substantiates the existence of intracranial artery-to-artery embolism as a cause of transient ischemic attacks and subsequent strokes, and ha...
