Flashcards in Stroke Deck (16):
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

16

TPA

Clot buster that needs to be administered w/in 1-4.5 hrs
