greatest RF for stroke
Age
HTN
When would you do a non contrast CT
Stroke w/u
Kidney stones
Criteria for total anterior circulation stroke
All three of:
Unilateral weakness of the face, arm and leg
Homonymous hemianopia
Higher cerebral dysfx - dysphasia, visuospatial disorder
Criteria for partial anterior circulation stroke
Two of:
Unilateral weakness or sensory deficit of the face, arm and leg
Homonymous hemianopia
Higher cerebral dysfx
Types of anterior circulation strokes
Total anterior circulation strokes
Partial anterior circulation stroke
Lacunar syndrome
Criteria for lacunar syndrome
one of:
Pure sensory stroke
Pure motor stroke
Sensori-motor stroke
Ataxic hemiparesis
Criteria for posterior circulation syndrome
one of:
CN palsy + contralateral motor/sensory deficit
Bilateral motor/sensory deficit
COnjugate eye movement disorder
Cerebellar dysfx
isolated homonymous hemianopsia or cortical blindness
Indications for thrombolysis in stroke
Within 4.5 hours of symptom onset
Intracranial hemorrhage r/o on imaging
Indications for thrombectomy for stroke
Within 24hours of symptom onset
Acute ischemic stroke + confirmed occlusion of prox anterior circulation
+ potentially salvagable tissue
Indications for thrombectomy + thrombolysis in stroke
Wihtin 24 hours of symptom onset
Acute ischemic stroke +confirmed occlusion of prox anterior circulation shown AND potentially salvagable brain tissue
Aspirin indications stroke
Within 24hours of symptom onset and intracranial hemorrhage is excluded
Then daily aspirin for 2 weeks after onset of symptoms
Then definitive long term anti-thrombotic treatment
When is medical managment given over surgical management in hemorrhagic stoke management
Small deep hemorrhage
Lobar hemorrhage without either hydrocephalus or rapid neurological deterioration
Large hemorrhage and significant comorbids before the stroke
GCS score <8 unless this is because of hydrocephalus
Posterior fossa hemorrhage
When would you OFFER BP lowering in intracerebral hemorrhage
Present within 6 hours of symptom onset and SBP between 150-220mmHg
Aim for SBP 130-140mmHg within 1 hour of starting and maintain BP for at least 7 days
When would you CONSIDER BP lowering in intracerebral hemorrhage
> 6 hours of symptom onset or has a SBP >220MMhG
Aim for SBP 130-140 mmHg within 1 hour of starting treatment and maintain this BP for at least 7 days
