Blood Supply Flashcards
Anterior Spinal
Ventral 2/3 of Spinal Cord - paralysis/protopathic
Medial Medulla - ipsi tongue paralysis, contra sens and paresis
PICA
Dorsolateral Medulla and Pons
Medial Cerebellum
Cerebellar Cortex
“Wallenberg’s Syndrome” - vertigo, loss of balance, ipsi cerebellar signs loss of facial pain sensation and hoarsness
AICA
Inferior surface of cerebellar cortex
Dorsolateral Pons
- ipsi cerebellar signs (tremor, ataxia), facial paralysis, ipsi hearing loss, loss of pain and temp over face ispsilaterally
Basilar Branches
Pons and anterior midbrain (Crus Cerebri)
Paralysis and loss of sensation in the face, body and limbs; can also affect eye movements and cause diplopia
Superior Cerebellar
Superior surface of cerebellum
Dorsolateral corner of rostral Pons
Ipsilateral cerebellar signs, contralateral pain and temp loss, horners
PCA
Occipital Lobe
Medial portions of parietal/temporal
Ant/Post Midbrain
Crus Cerebri
Posterior Thalamus
-If unilateral: blindness in the visual dield contra to the affected side, alexia (left side).
-If bilateral as with “top of the basilar” occlusion: bilateral blindness, memory loss, somatosensory loss, coma and death
Posterior Communicating
Anterior Midbrain
Crus Cerebri
Thalamus
- contra paresis, coma/death
MCA
Lateral Cortex
Insula
deficits can include - contra paralysis and sensory loss; “apraxia”; aphasia; partial blindness
ACA
Medial surface of parietal and frontal lobes
- contra paralysis and sensory loss in leg and foot; sometimes, apraxia
Lenticulostriate
Basal Ganglia Amygdala Internal Capsule Anterior Thalamus Possibly, involuntary movements (basal ganglia); paralysis and sensory deficits over entire 1/2 of body, homonymous visual field deficits (internal capsule)
Anterior Choroidal
Hippocampus
Anterior Choroid plexus
Posterior internal capsule
With hemorrhage may cause paralysis, sensory deficits, visual field defect (Internal capsule)
“Top of the Basilar” = bilateral PCA
Bilateral blindness, memory loss
somatosensory loss, coma
