Flashcards in Blood Supply Deck (23):
1

anterior spinal distribution

ventral 2/3 of spinal cord and medial medulla

2

anterior spinal symptoms: branch in spinal cord

paralyis and loss of protopathic below occlusion (bilaterally)

3

anterior spinal symptoms: medial medulla

contralateral sensory loss and paresis
ipsilateral tongue aralysis

4

PICA distribution

dorsolateral medulla and pons, medial cerebellum and cerebellar cortex

5

PICA symptoms

wallenburg's syndrome: vertigo, loss of balance, ipsilateral cerebellar signs (tremor and ataxia), loss of facial pain and hoarseness

6

AICA distribution

inferior surface of cerebellar cortex, dorsolateral pons

7

AICA symptoms

ipsilateral cerebellar signs (tremor and ataxia), facial paralysis, ipsilateral hearing loss, and loss of facial protopathic sense ipsilaterally

8

basilar branches distribution

pons and anterior midbrain (crus cerebri)

9

basilar branches symptoms

loss of sensation in the face, body and limbs
can also affect eye movements and cause diploplia

10

superior cerebellar distribution

duperior surface of cerebellum, dorsolateral corner of rostral pons

11

superior cerebellar symptoms

ipsilateral cerebellar signs, contralateral protopathic loss and horner's syndrome

12

posterior cerebral distribution

occipital lobe, medial portions of parietal and temporal lobes, anterior and posterior midbrain, crus cerebri and posterior thalamus

13

posterior cerebral symptoms

unilateral: blindness in visual field contralateral to affected side, alexia if on left side
bilateral: (top of the basilar occlusion) bilateral blindness, memory loss, somatosensory loss, coma and death

14

posterior communicating branches distribution

anterior midbrain, crus cerebri and thalamus

15

posterior communicating symptoms

contralateral paresis, coma and death

16

middle cerebral distribution

lateral surface of cortex and insula

17

middle cerebral symptoms

contralateral paralysis and sensory loss, apraxia, aphasia and partial blindness

18

anterior cerebral distribution

medial surface of parietal and frontal lobes

19

anterior cerebral symptoms

contralateral paralysis and sensory loss in leg and foot, sometimes apraxia

20

lenticulostriate distribution

basal ganglia, amygdala, internal capsule and anterior thalamus

21

lenticulostriate symptoms

involuntary movements (BG), paralysis, sensory deficites over entire 1/2 of body, homonymous visual field deficits (internal capsule)

22

anterior choroidal distribution

hippocampus, anterior choroid plexus, posterior internal capsule

23

anterior choroidal symptoms

paralysis, sensory deficits and visual field defect (internal capsule)
