Stroke / CVA Flashcards
(41 cards)
Types of stroke
Iscemic
Transient Ischemic Attack
Hemorrhagic (traumatic vs spontaneous)
Types of Hemorrhagic stroke
Traumatic
- Epidural Hematoma
- Subdural Hematoma
Spontaneous
- Subarachnoid Hemorrhage > Berry Aneurysm
- Spontaneous Intracerebral Hemorrhage
Most common type of stroke
Ischemic (87%)
Stroke, higher incidence for men or women?
Men, until age 75+ then women
3 pathologic processes that lead to ischemic stroke
- Thrombosis (2/3)
(Common/Internal Carotids or Circle of Willis + branches) - Embolism (1/3)
(cardiac, artery-artery) - Systemic Hypotension
Blood disorders associated w Ischemic stroke
Prothrombin gene mutation
Factor V Leiden
Sickle Cell
Infection / Inflammatory States (HIV, Cancer, Crohns)
Patient presenting w aphasia, agraphia, memory/behavior, gaze, motor/sensory might be what kind o stroke
Cortical Stroke (ischemic)
Patient presenting w predominantly motor deficits on opposite side (face, arm, leg) might be what kind of stroke
Subcortical Stroke (ischemic)
Patient presenting w occulomotor impairment, CN findings (facial, disphagia, nystagmus) might be what kind of stroke
Subcortical Brainstem Stroke (ischemic)
Patient presenting w profound nausea, vomiting, headache, double vision, imbalance, eye movements. OR COMATOSED.
Brainstem Stroke
Stroke that shows non-focal symptoms beyond 1 vascular territory, autonomic symptoms: tachy, sweaty, pallor
Hypoperfusion
Routine blood work for stroke
CMP
CBC + Platelet
PTT / PT / INR
ESR
Lipids
Glucose
Urinalysis
Drug Screen
3 infectious processes to be considered/ruled out w stroke
Syphilus
HIV
Lymes
Diagnostic imagine for stroke
- CT, acute phase. Differentiates ischemic from hemorrhagic
- MRI : better for acute ischemic
Gold Standard Angiography for stroke
Digital Subtraction Angiography
Angiography to order in stroke code if pt is intervention candidate
CTA - Computer Tomography Angiography
if kidney function is ok
Angiography to order in stroke if pt has poor kidney function
MRA - Magnetic Resonance Angiography`
Acute management of stroke
ABCs (Airway, Breathing, Circulation)
STAT CT +/- CTA
IV Access
Check Anticoag status and Glucose
Manage BP, < 220 / < 110
(get timeline from pt / family)
tPA for stroke?
Approved for use within first 3 hours of acute stroke
pts > 18yrs
stroke causing clinically significant neuro deficit
Tx Stroke
tPA (if candidate, 3 hrs etc)
Thrombectomy / lysis if large vessel anterior
Antiplatelet therapy: ASA 325mg (or anticoag, if indicated)
Statin: Atorvastatin
Antiplatelet vs Anticoag Tx stroke
Anitplatelet for Iscemic / TIA
Anticoag for Cardiac Emboli
Hemorrhagic stroke Tx
control BP, determine cause, c/s NSU (ABCs, CT/A, LP, pain mgmt., rainbow labs,
ECG, C Enzymes, CXR,
TTE (transthoracic echo)
Which cranial artery is known to cause epidural hematoma -hemorrhagic stroke
Middle Meningeal Artery
CT shows lens shaped, convex bleed
Epidural Hematoma
