Neuro - Cordingley - Stroke

Front 1

Describe blood supply to brain

Back 1

Aortic arch --> common carotid a. --> Internal and external carotid a. -->

Internal carotid goes to brain --> circle of willis --> vertebral a. --> Basilar a. --> circle of willis including anterior communicating a.

Front 2

Which supplies the scalp and superficial stuff of brain, internal or external carotid a?

Back 2

external carotid a.

Front 3

What does the middle cerebral a. supply?

Back 3

Outer temporal lobe, parietal lobe, frontal lobe

Front 4

What does the posterior cerebral a. supply?

Back 4

Underside of temporal lobe, Occipital lobe

Front 5

What does ant. cerebral supply blood to?

Back 5

frontal cortex = executive functioning

Front 6

Stroke in Wernicke's area means what?

Back 6

can speak but can't understand

Front 7

Stroke in Brocca's a. means what?

Back 7

Can't speak but can understand

Front 8

What are the two types of arterial stroke?

Back 8

Hemorrhage and Infarction

Front 9

What are the two types o f Arterial stroke hemorrhages?

Back 9

Subarachnoid and Intraparenchymal

Front 10

What are the two types of Arterial stroke Infarctions?

Back 10

Large vs. Small vessel and Thrombotic vs. Embolic

Front 11

What USUALLY causes a subarachnoid hemorrhage?

Back 11

Aneurysm

Front 12

What blood structure are MOST aneurysms near?

Back 12

circle of willis

Front 13

How do we manage aneurysms?

Back 13

endovascular coiling (=coil around aneurysm) and surgical clipping

Front 14

What are intraparenchymal hemorrhages most often associated with?

Back 14

HTN OR arteriovenous malformation

Front 15

Where do Charcot-bouchard aneurysms occur?

Back 15

penetrating arteries ie arteries that penetrate deep into brain (dif from arteries near cicrle of willis = berry or saccular aneurysm)

Front 16

Which aneurysm is more likely to bleed, berry or charcot-bouchard?

Back 16

Berry (saccular)

Front 17

What does a large vessel infarct look like on imaging?

Back 17

large vessel = LARGE section or wedge shaped infarcted area

note it will be more wedge shaped than your typical arachnoid/subdural hemorrhage

Front 18

What does occlusion of small vessels cause (for ex occlusion of small penetrating artery)?

Back 18

Lacunar infarction

Front 19

What does a lucanar infarction look like on imaging?

Back 19

A small dark spot

Front 20

Whats the difference between embolus and thrombus?

Back 20

Embolus = came from somewhere else

Thrombus = block occurs where the pathology is

Front 21

Where do half of all emboli come from?

Back 21

a-fib = liquid blood becomes solid blood and embolizes
