Stroke Flashcards
What are the 2 types of stroke?
- Ischaemic
- Haemorrhagic
What are risk factors for ischaemic stroke?
- Age
- HTN
- Smoking
- Hyperlipidaemia
- DM
- AF
What are the risk factors of haemorrhagic stroke?
- Age
- HTN
- AV malformation
- Anticoagulation therapy
What is the Bamford/Oxford Stroke classification for TACI?
Total anterior circulation: MCA, ACA
- Unilateral hemiparesis/hemisensory loss of the face, arm and leg
- Homonymous hemianopia
- Higher cognitive dysfunction e.g. dysphasia
What is the bamford classification for PACI?
Partial: involving the smaller arteries
2 of the following:
- Unilateral hemiparesis/hemisensory loss of the face, arm and leg
- Homonymous hemianopia
- Higher cognitive dysfunction e.g. dysphasia
What is the bamford classification for lacunar infarct?
- involves perforating arteries around the internal capsule, thalamus and basal ganglia
- presents with 1 of the following:
1. unilateral weakness (and/or sensory deficit) of face and arm, arm and leg or all three.
2. pure sensory stroke.
3. ataxic hemiparesis
What is the bamford classification for POCI?
- involves vertebrobasilar arteries
- presents with 1 of the following:
1. cerebellar or brainstem syndromes
2. loss of consciousness
3. isolated homonymous hemianopia
What are the common symptoms of haemorrhagic stroke?
- Decrease in consciousness
- Headache
- N+V
- Seizures
What is the tool used to recognise stroke in A+E?
ROSIER
How is stroke managed?
- Exclude hypoglycaemia
- CT brain
- 300mg aspirin once haemorrhage excluded for 2 weeks
- Thrombolysis with alteplase can be used if within 4.5 hours of onset
- Thrombectomy can be used for strokes in proximal anterior/posterior circulation within 24 hours of symptoms
What is the long term management of stroke?
- Assess for underlying cause e.g. cartoid imaging, ECG and intervene where possible
- Clopidogrel 75mg once daily
- Atorvastatin started after 48 hours
- Control BP and Diabetes
- Control modifiable risk factors
- Rehab
