Transient Ischaemic Attack 'TIA'
- Also known as a mini stroke it is caused by a temporary cut off of blood to the brain
- FAST & ROSIER
- People who have had
a TIA often do not
present with
neurological symptoms
at the time of
assesment
- These people
should be assessed
for thier subsequent
risk of stroke
- The ABCD2 system is
used which is optimized to
predict the occurance of
stroke within 2days but
can predict up to 90days
- It uses 5 independent factors and adds up the
scores to calculate risk
- Factors assessed include:
- Age >60
- High Blood pressure
- Unilateral weakness with
or without speech
impairment
- Speech
impairment without
unilateral
weakness
- TIA lasting >60mins
- TIA between 10-59mins
- Diabetes
- Age >60
- It uses 5 independent factors and adds up the
scores to calculate risk
- People with a ABCD2 score of 4 or
above are high risk
- Asprin daily
- Investigation within 24 hours
- Urgent brain imaging
- DWI MRI *
- CT to exclude extracerebral
haemorrhage & tumour
- DWI MRI *
- Urgent brain imaging
- Measures for secondary prevention introduced
as soon as diagnosis is confirmed
- Asprin daily
- The ABCD2 system is
used which is optimized to
predict the occurance of
stroke within 2days but
can predict up to 90days
- These people
should be assessed
for thier subsequent
risk of stroke
- People with two or more
TIA's in a week
- Should be treated as
high risk even if
ABCD2 score may be
less than 3
- Should be treated as
high risk even if
ABCD2 score may be
less than 3
- People who have suspected TIA but are low
risk (ABCD2 less than 3)
- Aspirin daily
- Specialist assesment within 1 week
- Brain imaging
- DWI MRI
- DWI MRI
- Brain imaging
- Measures for secondaray prevention introduced
and discussion of risk factors
- Aspirin daily
- People who have had a TIA or stroke may have
narrowing of the carotid artery
- Those considered as candidates for carotid endarterectomy
- Carotid imaging within 1 week
unless last symptom was
more than 1 week prior
- Those who have 50-99% carotid stenosis
according to NASCET(North American
Symptomatic Carotid Endarterectomy Trail) or
70-99% according to ECST (European Carotid
Surgery Trailists Collaborative Group)
- Assesed and reffered for carotid
endarterectomy within 1 week
- Undergo surgery within 2 weeks
- Receive
- Blood pressure drugs
- Cholesterol lowering drugs & diet
- Lifestyle advice
- Blood pressure drugs
- Assesed and reffered for carotid
endarterectomy within 1 week
- Those who have less than 50% carotid
stenosis according to NASCET or less
than 70% according to ECST
- Not undergo surgery
- Blood pressure drugs
- Cholesterol lowering drugs and diet
- Lifestyle advice
- Not undergo surgery
- Those who have 50-99% carotid stenosis
according to NASCET(North American
Symptomatic Carotid Endarterectomy Trail) or
70-99% according to ECST (European Carotid
Surgery Trailists Collaborative Group)
- Carotid imaging within 1 week
unless last symptom was
more than 1 week prior
- Those considered as candidates for carotid endarterectomy
- Cartotid Artery Imaging
- US
- Linear shows
bifurcation - most
common site of
disease
- Spectral doppler
- Velocity inofrmation
- Higher velocity =
higher degree of
stenosis
- Degree of
stenosis
calulated from
readings
- Velocity inofrmation
- Linear shows
bifurcation - most
common site of
disease
- MRA
- CTA
- US
- Cardiac Imaging
- Should be performed
for those with normal
brain scans to identify
the central source of
emboli
