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...

• There are two main types of strokes: ischemic and hemorrhagic. • Ischemic strokes are far more common than hemorrhagic strokes. • The brain has a blood supply which is fairly consistent between individuals. • Ischemic strokes can be due to large-vessel atherosclerosis, aortocardioembolism, small-vessel occlusion, other determined causes, and undetermined causes. • Hemorrhagic strokes are most...

Background Patients with hemorrhagic infarcts appear to constitute a high-risk group in acute myocardial infarction (AMI). However, the clinical implications of hemorrhagic versus non-hemorrhagic infarcts are currently unclear, warranting a more systematic and mechanistic approach towards understanding the underlying consequences. The question of whether hemorrhage is simply a bystander or cont...

Acalculous hemorrhagic cholecystitis is a rare complication of acute cholecystitis and is associated with a high mortality rate. Magnetic resonance imaging (MRI) is usually not performed for the diagnosis of acute cholecystitis, but it is a valuable imaging modality and affords excellent tissue contrast for the diagnosis of hemorrhagic cholecystitis and the detection of hematoma within the gall...

Eighteen consecutive patients satisfying predefined clinical criteria for embolic strokes were prospectively studied by sequential computerized tomography (CT). Their findings were compared to CT scans obtained from patients presumed to have suffered thrombotic strokes. Our data reveal that the CT appearance of hemorrhagic infarction is likely to occur twice as frequently (22%) in CT scans of s...
