[stroke]: Stroke causing cardiac emboli (30% of strokes) can be caused by what 4 heart conditions
[stroke]: Where in the brain does a 'watershed/boundary zone' stroke occur (not a brain area )
Infarct in the area between the supply of two arteries (i.e. decreased blood supply).
[stroke]: When does a 'watershed/boundary zone' stroke occur
Sharp drop in BP (sepsis)
[stroke]: Presenting >40yrs with migraine, TIA and mood swings is the main genetic cause of stroke. What is this called.
[stroke]: What does CADASIL stand for
Cerebral autosomal dominant arteriopathy with subcortical infarcts & leucoencephalopthy
[stroke]: What gene is responsible for CADASIL
[stroke]: Fibromuscular dysplasia or neck trauma may cause stroke by spontaneous .... dissection
[stroke]: Name 4 modifiable risk factors which are non-obvious
[stroke]: Name the 2 places other than cerebral where infarcts can occur
[stroke]: What would a lacunar infarct affect anatomically (4)
[stroke]: in a lacunar stroke what would indicate that something other than the thalamus has been affected
Consciousness/cognition is unaffected
[stroke]: Where would you suspect the infarct if the patient reported disturbances in vision or gaze.
[stroke]: Locked in syndrome is associated with infarct in which area
[stroke]: What is the acute (1hr) management of stroke in order of priority (mneumonic)
BP, pulse, ECG
Blood glucose (4-11)
[stroke]: If a patient has a stroke and has a high BP, in what 2 circumstances should you treat.
[stroke]: Within what time should thrombolysis be given
[stroke]: What drug is used in thromobolysis if expert clinicians, not CIs and <4.5hrs are all present.
Alteplase (tissue plasminogen activator)
[stroke]: What are the non-numerical CIs for thrombolysis
Major infarct/haemorrhage on CT
recent birth/surgery/trauma/uncompressible puncture
Previous CNS bleeds
[stroke]: What is the INR cut-off which is a CI for thrombolysis
[stroke]: What is the BP cut-off which is a CI for thrombolysis
[stroke]: What is the plts cut-off which is a CI for thrombolysis
[stroke]: The basilar artery forms the .... arteries
[stroke]: The internal carotid artery forms the ... and ... arteries
[stroke]: What 2 parts of the cerebral cortex does the anterior cerebral artery supply
[stroke]: The medial and frontal cerebral cortices are concerned with contralateral ... and ... (if slightly milder)
[stroke]: If the legs of a patient are affected but the face is spared which artery is likely to be affected.
[stroke]: Akinetic mutism describes a lack of movement and speaking. It can be caused by damage to the cingulate gyrus. .... is the location of the infarct.
Bilateral ant. cerebral artery
[stroke]: Contralateral hemiparesis/hemisensory loss, especially of face and arms indicates the ... is infarcted.
[stroke]: the middle cerebral artery supplies the optic radiation. What might and infarct cause.
Contralateral homonymous hemianopia.
[stroke]: Middle cerebral artery infarct on the dominant side of the brain is associated with ...
Dysphasia (disorder of language)
[stroke]: Middle cerebral artery infarct on the non-dominant side of the brain is associated with ...
visuo-spatial disorders (gets lost/ cannot dress)
[stroke]: Why with a posterior cerebral artery infarct do you get homonymous hemianopia with macular sparing
Macula receives collateral blood supply from the middle cerebral artery.
[stroke]: the brainstem is supplied by which arterial system
Vertebro-basilar (i.e. not carotid)
[stroke]: Damage to the ventral pons can be casued by infarct of which artery
[stroke]: infarct of the pontine artery causes ... syndrome due to ischaemia of ventral pons.
[stroke]: Ischaemia of the lateral medulla and the inferior cerebellum is caused by reduced flow through which 2 arteries
posterior inferior cerebellar
[stroke]: How does lateral medullary syndrome present
soft palate paralysis
analgesia ipsilateral on face, contra on body.
[stroke]: What arteries are implicated in lateral medullary syndrome (2)
posterior inferior cerebellar
[stroke]: If BP differs by >20mmHg in each arm what might you suspect
subclavian artery stenosis
[stroke]: If brain ischaemia is related to use of the pts arm which syndrome might be present
Subclavian steal syndrome
