Flashcards in Types of strokes Deck (15):
1

The common Carotid artery gives way to what other major arteries?

Internal and external carotid arteries internal, internal-> anterior and middle cerebellar arteries

2

How does an Anterior Cerebellar Artery (ACA) stroke present?

Contralateral sensory loss and hemiparesis, Legs > arms

3

What is one reason why an ACA stroke may have minimal effects?

If the clott/bleed occurs proximal to the anterior communicating artery blood from the contralateral side is allowed to flow.

4

What areas of the brain does the ACA supply?

Anterior two thirds of the medial cerebral cortex

5

Where does the Middle Cerebral Artery (MCA) supply blood to?

The MCA supplies the lateral cerebral cortex, basal ganglia, and a large portion of the internal capsule.

6

A stroke in the MCA would cause?

Contralateral sensory loss and hemiparesis Arms > Legs

 Motor speech aphasia,

Perceptual dysfunction,

sensory ataxia,

loss of conjugate gaze to the contralaterl side,

homonymous hemianopsia

7

What are the symptoms of Medial Medullary syndrome?

(stroke of lower basilar artery)  

Ipsilateral paralysis of the tongue 

contralateral paralysis of arm and leg with impaired sensation

8

What are the symptoms of  Lateral Medullary Syndrome?

(stroke of vertebral,posterior inferior cerebellar,basilar atery "PICA") 

Ipsilateral cerebellar symptoms 

Horners syndrome

dysphasia

impaired speech

deminished gag reflex

sensory loss of ipsilateral arm, trunk, leg

contralateral loss of pain and temp

9

What is Horner's syndrome?

Triad of symptoms:

Miosis(pupil constriction), ptosis, decreased sweating

10

List cerebellar symptoms associated with stroke

ataxia,

nystagmus,

nausea,

vomiting, 

vertigo, 

dysmetria

dysdiadochokinesia

11

Symptoms of Basilar Artery syndrome.

Locked in syndrome

quadriplegia and bulbar paralysis

anarthria with preserved consciousness. 

12

What are sypmtoms of Medial inferior Pontine Syndrome

Ispilateral: cerebellar signs, paralysis of conjugate gaze, diplopia

 

Contralateral: hemiparesis, impaired sensation

13

Symptoms of Lateral inferior Pontine syndrome (infarction of Anterior Inferior Cerebellar Artery "AICA")

Ispilateral:facial paralysis, paralysis of conjugate gaze towards lesion, deafness, tinnitus, impaired facial sesation, cerebellar signs

 

Contralateral: impairement of pain and temperature

14

Symptoms of Posterior Cerebral Artery (PCA) stroke

Homonymous hemianopsia

contralateral sensory loss

thalamic syndrome

involuntary movements

Webers syndrome

Visual symptoms

15

What are the symptoms of Webers syndrome?

oculomotor nerve palsy with contralateral hemiplegia
