CVA Case 3 Flashcards
Name the three types of CVA
- Ischemic
- Hemorrhagic
- Small Vessel (Lacunar)
This type of stroke is caused by insufficient blood flow to part of the brain resulting in neuro deficits that last > 24 hrs
Ischemic
If a stroke lasts < 24 hrs it is called what?
TIA
= transient episode of neurological dysfunction caused by focal brain, spinal cord, or retinal ischemia, without acute infarction
What type of stroke is this?
Occlusion forms locally at the site
Thrombotic
What type of stroke is this?
Clot breaks off in another location and travels to the brain
Embolic
What type of stroke is this?
- Extravasation of blood into the brain
- Ie: aneurysm, head trauma
Hemorrhagic
What type of stroke is this?
- From occlusion of small arterioles
- Usually from longstanding HTN
Lacunar
Some risk factors for CVA are?
Increasing age Afib Hypercoagulable states HTN Smoking Diabetes Dyslipidemia Carotid Stenosis TIA Physical Inactivity & obesity Drug use
Signs and symptoms of stroke depend on what?
The area of the brain was deprived of blood flow

May have apraxia and sensory neglect is characteristic of an anterior, middle or posterior stroke?
Middle Cerebral Artery (MCA)
In a stroke, a patient’s eyes will gaze towards or away from the lesion?
Towards
Stroke on R side so they will gaze to R side
Homonymous hemianopsia affecting the contralateral visual field that may be denser superiorly is characteristic of an anterior, middle or posterior stroke?
Posterior Cerebral Artery (PCA)
Anomic aphasia (difficulty naming objects) is characteristic of an anterior, middle or posterior stroke?
Posterior Cerebral Artery (PCA)
Alexia without agraphia (inability to read, but able to write) is characteristic of an anterior, middle or posterior stroke?
Posterior Cerebral Artery (PCA)
Visual agnosia is characteristic of an anterior, middle or posterior stroke?
Posterior Cerebral Artery (PCA)
Contralateral hemisensory loss and hemiparesis is characteristic of an anterior, middle or posterior stroke?
Posterior Cerebral Artery (PCA)
Unilateral headache is characteristic of an anterior, middle or posterior stroke?
Posterior Cerebral Artery (PCA)
Memory impairment is characteristic of an anterior, middle or posterior stroke?
Posterior Cerebral Artery (PCA)
Oculomotor (III) nerve palsy is characteristic of an anterior, middle or posterior stroke?
Posterior Cerebral Artery (PCA)
___________ involves absence of cortical signs (aphasia, agnosia, neglect, apraxia, hemianopsia), plus one of the following:
- Pure motor hemiparesis (Can’t move body parts well)
- Pure sensory hemiparesis (can’t feel face)
- Ataxic hemiparesis (ipsilateral)
- Sensorimotor stroke (weak and numb body parts)
- Dysarthria/clumsy hand syndrome
Lacunar Infarction
What test should we do for evaluation of CVA?
CT head (non-contrast): to eval for hemorrhage
What is the inclusion criteria for tPA administration?
Hint:
- Age
- Clinical dx
- Time

- Recent intracranial or intraspinal surgery
- Serum glucose < 50
Relative Exclusion criteria for tPA (basically warnings)
- Minor or isolated neurologic signs
- Rapidly improving stroke symptoms
- Major surgery or serious trauma in the previous 2 weeks
- GI or urinary tract bleeding in the previous 3 weeks
- MI in previous 3 months

Relative exclusion criteria from 3-4.5 hours after sx onset
- Age >80
- Oral anticoagulant use regardless of INR
- Severe stroke (NIHSS score >25)
- Combination of both previous ischemic stroke and diabetes
In an ischemic CVA, Before thrombolysis: lower SBP to _______ and DBP to _______
Before thrombolysis: lower SBP to <185 and DBP to <110
After an inschemic stroke, BP needs to be maintained at ________ for at least 24 hours
Afterward, BP needs to be maintained <180/105 for at least 24 hours
Antithrombotic therapy for CVA?
- Aspirin, clopidogral (Plavix), or aspirin-extended release dipyridamole (Aggrenox) all choices
Antithrombotic therapy for CVA for patients with Afib?
Warfarin or NOAC for those with afib
These are all important HPI signs of what?

A stroke
Admit note acronym- ADCVAANDISML stands for what?
Admit to Diagnoses Condition Vital signs Activity Allergies Nursing Diet IV Special instructions Medication Labs/Xrays
When is the CHAD2 criteria used?
To determine a patient’s risk for stroke that has afib and when to give them anticoags
If a patient has a chads2 score of 2 or greater than 2, what should you do?
