QUESTIONS
1. Posterior Cerebral Artery (PCA) Arises from basilar. Supplies Occipital Lobe ,
Midbrain, Thalamus, Pineal Gland, Choroid
Plexus, and Corpus Callosum
2. Symptoms of PCA Stroke -Contralateral Visual Field Homonymous
hemianopia
-Visual Agnosia (unable to interpret/recognize
visual information)
- Weber's Syndrome (3rd nerve palsy +
contralateral hemiplegia)
-Parinaud's Syndrome (Impaired upwards gaze,
convergence-retraction nystagmus, primary
conjugate downward gaze)
,3. Anterior Inferior Cerebellar Artery
(AICA) Feeds anterior inferior parts of the cerebellum
4. Symptoms of AICA Stroke Lateral Pontine Syndrome: vertigo, vomiting,
nystagmus, falling towards the side of the lesion,
ipsilateral loss of sensation to the face,
ipsilateral facial paralysis, ipsilateral hearing
loss
5. Posterior Inferior Cerebellar Artery
Feeds cerebellum, superior section of the
(PICA)
medulla,. Choroid plexus and fourth ventricle
6. Symptoms of PICA Stroke Wallenburg Syndrome (lateral Medullary
Syndrome): Loss of pain and temperature
sensation in the contralateral trunk and
ipsilateral face
7. Basilar Artery An artery, formed by the fusion of the vertebral
arteries, that supplies blood to the brainstem
(medulla and pons) and to the posterior cerebral
arteries.
8. Symptoms of Basilar Artery Stoke Coma, quadriparesis, ataxia, dysarthria, CN
dysfunction and visual deficits, Locked in
Syndrome, Intranuclear Opthalmoplegia, gaze
paresis, Millard Gulber Syndrome CN VI VII
damage (diplopia facial weakness, loss of
, corneal reflex), Nausea, vomiting, diplopia, gaze
palsy, dysarthria,. vertigo, tinnitus, hemiparesis,
and quadriplegia.
9. Anterior Cerebral Artery (ACA)
Feeds the media portion of the frontal and
parietal lobes as well as the corpus callosum
10. Symptoms of ACA Stroke
Contralateral motor/sensory deficits impacting
legs > arms
11. Middle Cerebral Artery (MCA) Feeds majority of the frontal, parietal, and
temporal lobes, basal ganglia, internal capsule. It
is divided M1 - M4
12. Symptoms of MCA Stroke -Aphasia if dominant hemisphere
-Neglect if non-dominant hemisphere
-Contralateral motor/sensory loss of
face/arm/leg with Arms > Legs
-Anosognosia: neglect or lack of self awareness
13. Venous Vascular Anatomy
Venous channels enter into venous sinuses
located in the Dura matter.
14. Superior Sagittal Sinus
Travels posteriorly between the cerebral
hemispheres towards the occiput
, 15. Straight Sinus
Travels along the tentorium, draining blood from
the superior cerebellar veins.
16. Transverse Sinus
Travels along the base of the occiput laterally
and forwardly
17. Sigmoid Sinus Begins beneath the temporal bone and travels to
the jugular foramen where it becomes the
internal jugular veins
18. Stroke Pathophysiology Arterial blood flow to the brain tissue fails to
meet metabolic demands resulting in cell
damage or death. ISCHEMIA FIRST THEN
INFARCT.
19. Penumbra Zone surrounding the core infarct, damaged by
ischemia but not yet infarcted
---- functionally silent yet metabolically active
20. Hypoxia leading to Necrotic Pathway
Cell energy failure
21. Hypoxia leading to Apoptotic
Pathway Programmed cell death in the penumbral zone
