Cerebrovascular Disease

  1. 1. Cerebrovascular Disease <ul><li>Ischemic Stroke </li></ul><ul><li>Hemorrhagic Stroke </li></ul>
  2. 2. ISCHEMIC STROKE <ul><li>Also known as brain attack </li></ul><ul><li>is a abrupt loss of function resulting from disrupted blood supply to a part of the brain. </li></ul>
  3. 3. Five Types according to causes: <ul><li>Large artery thrombosis – are due to atherosclerotic plaques in the large blood vessels of the brain. Thrombus formation and occlusion at the site of the atherosclerosis result in ischemia and infarction. </li></ul><ul><li>Small penetrating artery thrombosis – affects one or more vessels and are the most common type of ischemic stroke. </li></ul><ul><li>- also known as Lacunar strokes because of the cavity that is created once the infracted brain tissue disintegrates. </li></ul><ul><li>Cardiogenic embolic strokes – are associated with cardiac dysrhythmias, usually atrial fibrillation. Emboli originate from the heart and circulate to the cerebral vasculature, most commonly the left middle cerebral artery, resulting in a stroke. Emboli stroke may be prevented by the use of anticoagulant therapy in patients with atrial fibrillation. </li></ul><ul><li>Cryptogenic stroke – iatrogenic. </li></ul><ul><li>other strokes – from the use of cocaine, coagulopathies, migraine, and spontaneous dissection of the carotid or vertebral arteries. </li></ul>
  4. 4. Stroke Continuum: Time Course Classification <ul><li>Transient Ischemic Attack </li></ul><ul><li>- may serve as a warning of approaching strokes </li></ul><ul><li>- greatest incidence is in the first month following the first attack. </li></ul><ul><li>- temporary episodes of neurologic dysfunction manifested by a sudden loss of motor, sensory, or visual function. </li></ul><ul><li>- last for a few seconds or minutes but no longer than 24 hours. </li></ul><ul><li>Reversible Ischemic Neurologic Deficit </li></ul><ul><li>- sign and symptoms are consistent but more distinct than a TIA </li></ul><ul><li>- last for more than 24 hours </li></ul><ul><li>- symptoms revolve in days without permanent neurologic deficits. </li></ul><ul><li>Stroke in Evolution </li></ul><ul><li>- worsening of neurologic sign and symptoms over several minutes or hours. </li></ul><ul><li>- Progressing stroke </li></ul><ul><li>Complete Stroke </li></ul><ul><li>- stabilization of the neurologic signs and symptoms </li></ul><ul><li>- indicates no further progression of hypoxic insult to the brain from this particular ischemic event. </li></ul>
