OME - Stroke Flashcards
3 types of stroke?
- Thrombotic:Ischemic
- Embolic: Ischemic
- Hemorrhagic stroke
What type of hemorrhage is a hemorrhagic stroke?
Intracerebral
Risk factors thrombotic stroke?
Same as MI:
- Smoking
- Obesity
- FH
- TIIDM, Htn, Hld
Sources embolic stroke?
- Carotid artery stenosis
- A fib
- Bad valve in heart
- Septic from IE
Presentation stroke?
- Focal neurologic deficit
What do the anterior cerebral arteries feed?
- Feet
2. Legs
What does MCA feed?
- Hands
- Arms
- Face
- Speech
What to PCA feed?
- Visual Cortex
What does the basilar artery arrive from?
2 vertebral arteries
What can cause locked in syndrome?
Occlusion basilar artery
Presentation occlusion vertebral basilar System?
Syncope
What controls coordination?
Cerebellum - finger to nose, ambulation (ataxia)
What side of body does right brain stroke impact?
Left body, and vice versa
Is bilateral body nuero loss ever stroke?
Never a SINGLE stroke
Presentation stroke patient?
- Vasculopath
- Afib/flutter, valve no on coag
- Young woman c/o neck pain post trauma
- Could be a carotid dissection
What is Cushing syndrome?
Sign of intracerebral hemorrhage.
- Altered breathing
- Bradycardia
- Hypertension
First step someone comes in w/ possible stroke?
Non contrast CT head
- The purpose is to rule out bleed
- Blood is white w/o contrast
- Also much rapider as don’t have to wait for contrast to distribute
Next step in hemorrhagic stroke after diagnosis?
- Drop BP with drip
- Call neuro: coil? clip? craniotomy?
- FFP if INR elevated
How does clip work? Coil?
Clip: need to open brain to close off vessel
Coil: Need to go through vessel
Next step after diagnosing nonhemorrhagic stroke?
Decide if we give TPA
Work up ischemic stroke if survive?
- 2d Echo (TTE) - vegetation?
- Carotid US -
- EGK monitoring - Afib or flutter?
Next step if stroke and afib or flutter?
Anticoagulation: 1. Warfarin or 2. NOAC ***Heparin bridge NOT needed
Next step in stroke if thrombus on TTE?
Anticoagulation: 1. Warfarin or 2. NOAC ***Heparin bridge IS needed
Next step in stroke if Carotid artery stenosis?
- Less than 70% no symptoms:
- Medical mgmt - Greater 70% symptomatic:
- Surgical mgmt - Greater 80% no symptoms:
- Surgical MGMT
