What kind of stroke is it? : What kind of stroke is it? Infarct: thrombo-embolic and ischemia Or Haemorrhage: burst of an artery Only a CT can tell According to oxford community stroke project 1991 : According to oxford community stroke project 1991 Cerebral infarction 82% Primary I.C Haemorrhage 10% Sub-arachnoid haemorrhage 8% Can you tell which part the brain is damaged : Can you tell which part the brain is damaged Clinical features and examination can help you to do this. Different type of stroke Common type of infarct : Common type of infarct Bamford definition T.A.C.I: Total anterior circulation infarct P.A.C.I: Partial anterior circulation infarct L.A.C.I: Lacunar infarct P.O.C.I: Posterior circulation infarct The individual infarct problems are best referred to as syndrome due to several clinical features seen from each one; e.g. TACS Total anterior circulation infarct : Total anterior circulation infarct All 3 of Higher function loss dysphasia dyspraxia visuospatial neglect inattention Homonymous hemianopia Motor/sensory deficit >2/3 face, arm, leg Partial anterior circulation infarct : Partial anterior circulation infarct Any one of these 2 out of 3 of TACI 1. higher function loss 2. homonymous hemianopia 3. motor and sensory deficits Higher function loss alone Limited motor / sensory deficit Lacuna infarct : Lacuna infarct Any one of these Pure motor stroke ( in 2 of 3 of arm, face or leg ) Pure sensory stroke ( in 2 of 3 of arm, face or leg) Sensorimotor stroke ( in 2 of 3 of arm, face or leg) Ataxic hemiparesis Lacunar infarction must have none of these: : Lacunar infarction must have none of these: New dysphasia New visuospatial No vertebrobasilar features Proprioceptive sensory loss alone Posterior circulation infarct : Posterior circulation infarct Any of these features: Cranial nerve palsy and contralateral motor/sensory deficit Bilateral motor OR sensory deficit Conjugate eye movement problems ( diplopia) Cerebella signs in limbs or truncal ataxia Illustration of anterior, posterior circulation + lacunar arteries : Illustration of anterior, posterior circulation + lacunar arteries Medial view of blood supply : Medial view of blood supply Areas of circulation : Areas of circulation Anterior circulation: divided into 1.anterior sup frontal , medial aspect of parietal and occipital lb 2.middle cbr art sup fro par, and somatosensory Posterior circulation: divided into 1.posterior cbr art sup occipital and inferior temporal 2. cerebella art supl cerebellum Lacunes or penetrating arteries: arise from ant & post communicating art to supply thalamus and basal ganglia. And the penetrating arteries from basilar supl the pons. Now match clinical features with possible of area of brain damage : Now match clinical features with possible of area of brain damage We would have case scenario later.
