1
Transient Ischemia Attack (TIA) vs. Stroke
TIA is transient neuro dysfunction from focal ischemia w/out acute infarction (tissue death)
2
Worldwide Stroke Burden
Highest stroke incidence/new cases in low-middle income countries, highest prevalence in developed nations
3
Stroke Incidence Race/Gender
B and H have higher than W
Men have higher incidence, but more older women so more stroke cases are actually women
4
2 Main Types of Stroke
Ischemic - 80%
Hemorrhagic - 20%
5
2 Kinds of Hemorrhagic Strokes
Intracerebral hemorrhage (60%, substance of brain, small b.v.s)
Subarachnoid Hemorrhage (40%, aneurysm bursts causing bleeding along surface)
6
4 Kinds of Ischemic Stroke
Atherthrombotic Cerebrovascular Disease (20%)
Lacunar (25%, small vessel disease)
Embolism (20%)
Cryptogenic (30%, unknown)
7
ESUS
Embolic stroke of undetermined source
8
3 Treatment for SAH
Reduce rebleeding risk w/ early surgical clipping or endovascular coiling
Reduce delayed ischemia
Reduce hydrocephalus (ventriculostomy)
9
2 Main Causes of Intracerebral Hemorrhage (and major sign)
Focal problems more common
Hypertension -> small vessel disease
Amyloid Angiopathy
10
2 Treatment for Intracerebral Hemorrhage
BP control
Reduce bleeding (reverse anticoags)
11
6 Infarct Subtype Classifications
Extracranial artherosclerotic (EATH)
Intracranial artherosclerotic (IATH)
Lacunar small vessel (LAC)
Cardioembolic (CEMB)
Conflicting mech (CONF)
Cryptogenic (CRYPT)
12
4 Requirements for Ischemic Stroke Workup
Brain imaging: Head CT/MRI
Extracranial vascular imaging: Carotid doppler/angiogram and shit
Intracranial vascular imaging
Cardiac assessment
13
2 Mechs for Artherosclerosis Cerebral Infarction
Hemodynamic - fluid failure
Embolism - a. 2 a.
14
Atrial Fibrillation
Most common arrythmia, common cause of cardiac embolism -> cerebral infarction
15
Brain Image of Small Vessel Disease -> Cerebral Infarction
Focal, deep infarct sparing surface
