2 When cerebral artery occlude

4 In the first few hours of vascular insult there is only a penumbral pattern (low CBF and high CBV due to maximally functioning autoregulation mechanism and collateral circulation). This is viable tissue at risk that could be saved, but it may not yet show diffusion restriction. Subsequently, the autoregulation mechanism starts to fail and the infarction core spreads, gradually reaching its final extent, which is the entire penumbra (low CBF region). The mean lesion-to-contralateral region CBV ratio of 0.19 (range, 0.03–0.36) may suggest a viability threshold. Parameters of cerebral hemodynamics: Cerebral Blood Flow (CBF): Represents instantaneous capillary flow in tissue. Cerebral Blood Volume (CBV): Describes the blood volume of the cerebral capillaries and venules per cerebral tissue volume. Mean Transit Time (MTT): Measures the length of time a certain volume of blood spends in the cerebral capillary circulation. MTT = CBV/CBF Time To Peak (TTP): A parameter inversely related to CBF in which reduction of blood flow results in an increase in the time needed for the contrast to reach its peak in the perfused volume of brain tissue.

6 DWI and ADC map demonstrate an area of diffusion restriction in the right MCA territory consistent with acute infarction. CBF and MTT map (PWI) demonstrate the infarct penumbra which is larger than the core, indicating the presence of salvageable tissue. CBV map (PWI) demonstrates infarct core which is slightly smaller than the area of diffusion restriction.

8 Patient imaged pre-tPA treatment at 1
Patient imaged pre-tPA treatment at 1.5 hours, with large left MCA occlusion (MRA), and a penumbral pattern with a large PWI lesion and small DWI lesion. Subacute studies post- tPA (day 5) show recanalisation, reperfusion and minimal expansion of the infarct core on DWI.

9 Ischemic stroke in middle cerebral artery territory
Ischemic stroke in middle cerebral artery territory. (A) Low flow area with irreversible damage on final magnetic resonance image (MRI) predicted by low oxygen consumption and decreased oxygen extraction fraction (OEF). Penumbra tissue outside the final infarct is characterized by preserved oxygen consumption and increased OEF. (B) Reperfusion is not effective if tissue is already damaged. (C) Effective reperfusion to viable (penumbra) tissue.

40 STROKE COMPLICATION !!!

41 Complications of stroke
Neurological deterioration in acute stroke; - decrease of level of consciousness - motor deficit progression

42 General medical complications

43 Prospectively collected data; suggest
direct effect of ischemic stroke account for most deaths within first week after stroke mortality resulting from medical complications predominate there after

44 Neurological deterioration in acute stroke
1.Recurrent stroke - The International Stroke Trial (IST) show recurrence rate (first 14 days) 2.8 % in those tx with aspirin 3.9% in those not receive aspirin - ASA ( mg) begin within 24 hrs after stroke is recommended to lower risk of early ischemic stroke recurrence(IST,CAST) Lancet 1997;349: Lancet 1997;349:

45 risk factors/predictors for stroke progression
Age Hx of DM Elevated SBP on admission Prior antiplatelets Hyperthermia Hyperglycemia High Hct Early positive CT brain

46

47 2.Hemorrhagic transformation
symptomatic (headache,worsening of focal deficit,decreased level of consciousness) asymptomatic

48 - prospective study; assess 65 pts
- prospective study; assess 65 pts. with acute supratentorial infarct - serial CT in 4 weeks 43%(28/65) found hemorrhagic transformation 5% (3/65) or 10% of pts.hemorrhagic transformation have neurological deterioration correlation between size of infarct and present of hemorrhagic transformation Stroke 1986;17:

49 Rate of hemorrhagic transformation (total and symptomatic) according to time to treatment

50 In case suspected ICH associated with thrombolysis; tx
hold drug infusion emergency CT blood component check &prepare cryo ppt,PRC,Platelet neurosurgical option for selected case

51 3.Cerebral edema - related to large infarct & tend to have delayed clincial deterioration most serious rising ICP – brain herniation As ICP rises CPP&CBF are reduced local increase in tissue pressure interfere local microcirculation -; worsening ischemia & 2’ cerebral damage - maximal edema occurs between day 2-5 - cause mainly by cytotoxic brain edema

52 2 hr after onset 24 hrs later with clinical deterioration
CT brain show subfalcial herniation , massive ACA+ MCA infarction with brain swelling and hemorrhagic conversion

53 treatment of elevated ICP in stroke
1. elevate head of bed 15-30’; both ICP & CPP are lowest while head elevate by 30’

54 2. hyperventilation act almost immediately to lower ICP
by leading to vasoconstriction 2’ to alkalosis of CSF hyperventilation pCO2 below 30 mmHg can induced ischemia via vasoconstriction J Neurosurgery 1991;75:

55 3.pharmacological treatment
3.1 manitol ; almost immediate decrease In whole blood viscosity leadind to vasoconstriction and decrease ICP(non infarcted brain) - maximal duration of effect on ICP range min (mean 88 min) - dose g/kg over 20 min repeat q 6 hr monitor fluid input/output,serum osmolarity typical maximum daily dose 2g/kg Circulation 1994;90: J Neurosurgery 1981;55: J Neurosurgery 1983;59: Acta Neurochir 1977;36: Neurology 2001;57:

56 4.Surgical intervention- specific condition
hemicreniectomy in case massive MCA infarction craniotomy or suboccipital craniectomy in case large cerebellar infarct & depressed level of consciousness secondary to BS compression

57 Right middle cerebral artery infarction

58 cranial vault is closed, fixed bony box, its volume is constant
cranial vault is closed, fixed bony box, its volume is constant. This volume is described by Monro-Kellie doctrine, v.intracranial (constant) = v.brain + v.CSF + v.blood + v.mass

59 4.Seizure and epilepsy - seizure & post ictal state lead to depressed level of consciousness & worsening focal neurological deficit - incidence of seizure after stroke ~ 8.6% early onset (</=2wks) occur 4.8% 40% occurred within 24 hrs late onset ( >2 wks) occur 3.8% ; predictor of recurrent seizure 55% of pts.late onset seizure developed epilepsy - status epilepticus – uncommon(9%) - AED recommended for seizure in acute stroke setting long term AED individualized Arch Neurol 2000;57: Neurology 1996;46:

60 5. Unknown causes of deterioration in small &large vessel infarct
early deterioration (within 7 days onset ) occurs in ~ 25% of pts. Stroke 2000;31: excluded of consciousness change ,progressive motor deficit --- cause mostly by lacunar infarct esp .DM Stroke 2002;33:

61 - mechanism – not well understood - hypothesis 1.thrombos propagation
2. microemboli or low perfusion from large vessel 3. excitotoxicity ; elevated serum glutamate & depressed serum GABA found associated with motor deterioration in first 48 hrs Neurology 1996;47: Stroke 2001;32:

62 4. inflammatory contribute; inflammatory marker ex
4. inflammatory contribute; inflammatory marker ex.IL6,TNF alfa elevate in case early deterioration 5.hypoperfusion, lower blood pressure Stroke 2002;33:

63 6. Systemic conditions -systemic process affect neurological status in stroke pts. by furthering cerebral ischemia or leading to neuronal dysfunction - transient worsening or recurrence of original symptom - ex. Fever ; potential mechanism – release of excitatory amino acid & hydroxyl radicals sedative medications J Neurochem1995;65: Neuroscience 1998;83:

64 General medical complications

65 General medical complications
A recent prospective study 95% patients had at least 1 medical complication 32% patients had at least 1 serious complication( immediately life treatening ,prolonged hospitalization or death) Stroke 1998;29:

66 Common complications after acute stroke
Falls % UTI % Chest infection % Pressure sore % Depression % Shoulder pain % DVT % Pulmonary embolism % Data derived from Langhome P,Stott DJ,Robertson L,et al.Medical complications after stroke; a multicenter study.Stroke2000;31 ; Data from a prospective multicentered study with patients followed up to 30 months.Of those patients,89 percent had ischemic strokes and 11 percent had primary intracerebral hemorrhage

RANTTAS investigators. Stroke 1998;29;

68 1)Systemic thrombotic complications
1.1Deep venous thrombosis(DVT) / pulmonary embolism leg paresis is predisposed to developing DVT , (75% paretic side) degree of paresis related graded risk of DVT peak incidence at 2-7 days risk of death from untreated prox DVT in stroke patients = 15% Arch Neurol1992;49: Stroke 2001;32:

69 Sign and symptom of DVT leg swelling and pain positive Homan’s sign Screening by duplex ultrasound

70

71 DVT(cont.) Pulmonary embolism
; % of early deaths after stroke in 2-4 weeks severe hypoxia Treatment by anticoagulant weighted against risk of bleeding esp. in case large stroke Stroke 2001;32:

72 2)Pulmonary complications
2.1Aspiration study by videofluoroscopy to assessment swallowing in post stroke patients 50% found abnormality bedside predictors ; aspiration to thin liquid shown spontaneous cough during test swallowing absent of gag reflex ( healthy elderly subjects ,bilaterally absent gag reflex found 43%) Stroke1999;30: J Commun Disord2001;34:55-72 Lancet1995;345:

73 Independent predictor of dysphagia
Initial presentation male gender age >70 yrs disabling stroke impair pharyngeal response,incomplete oral clearance Palatal weakness or asymmetry Dysphagia2001;16:

74 study ; at 6 month 87% return to their pre stroke diet 50% found evidence of swallowing abnormality on clinical assessment Stroke 1999;30:

75 Prevention of aspiration in patient dysphagia
Initial nil per os (NPO) for those who may be risk of aspiration ex.drowsiness at onset Retain NG tube in case of dysphagia ,choking,aspirate

76 Most common cause of fever in stroke patients in first 48 hours
2.2 Pneumonia ; Most common cause of fever in stroke patients in first 48 hours most common medical complication 2-4 weeks after supratentorial ischemic infarct 66% of cases cause by aspiration Aspirated of colonizes oropharyngeal material Stroke 1998;29: Stroke 1984;15:

77 Common site of lungs involvement;

Common organism ; CAP S.pneumonia,Strap.aureus, H. influenzae,Enterobacteriaceae HAP ; gram negative organism (include Pseudomonas) anaerobic in case putrid sputum,severe peridental dz,alcoholism

79 mechanical ventilation required
- high morbidity &mortality - Wijdicks and Scott series; 24 pts. found 3 major reasons for stroke pts. to require mechanical vent. 1. pulmonary edema (10) – neurogenic PE ? 2. brain swelling (8) 3. seizure (6) 17/24 died Mayo Clin Proc 1997;72:

80 3. Cardiac complications
3.1 arrhythmia through effects of ANS via combination of humurally mediated & directed effect -- EKG change more common in setting of stroke Prog Cardiovasc Dis1993;36:

81 one study ; follow 3 times EKG within the
first 1 week ischemic stroke pts who did not have any hx of pre existing heart dz found that only 23 % had normal tracing Angiology 1990;41:

82 series using control matched for age,previous hx of heart dz , factors known to be associate with increase risk of arrhythmia ; presence of heart dz did not appear to confer an increased risk of arrhythmias Association between stroke and arrhythmia Stroke1982;13:

83 Cardiac arrhythmia after stroke
QTc prolonged % (37) Tall U waves % (25 ) ST change % T wave changes % Sinus tachycardia % (22) LVH % Q wave %(22) AF %(13) VPCs %(13) Sinus bradycardia % 1’AV block % ST elevate,RBBB,LBBB NR(3,7,0) Arrhythmia detected in stroke patients without a known history of cardiac disease as documented by Ramani et al.

84 -occurrence of lethal arrythmia may be more common than anticipated
A series ; 6/30 had asystole,complete atrioventricular block , ventricular tachycardia Sudden cardiac death occur 1% of supratentorial ischemic infarct within first 30 days (+/- comorbid cardiac dz) JAMA1981;246: Stroke 1984;15:

85 Ventricular tachycardia
Complete AV block

86 3.2 elevated cardiac enzyme

89 treatment option; limit in setting of acute ischemic stroke ex
treatment option; limit in setting of acute ischemic stroke ex. Thrombolysis,combined antiplt,ACEI,beta blocker angioplasty may be option for coronary revascularization in acute stroke setting

90 4. genitourinary complication
4.1 urological complications - urinary incontinence ; common after stroke 32-79 % of stroke pts.on admission 25-28% on discharge stroke1998;29:

91 most common finding is detrusor hypereflexia cause by loss inhibitory input from higher centre leading to urinary urgency,frequency,urge incontinence detrusor hyporeflexia or areflexia lead to overflow incontinence,more common in hemorrhage (10% pt ischemic stroke in 72 hrs) J Uro 1996;156:

92 - anticholinergic drugs - diabetic cystopathy
other contributions to urinary retention; - anticholinergic drugs - diabetic cystopathy - bladder outlet obstruction Prevalence of incontinence post stroke decreases with time 20% at 3 month 8% at 1 yrs 3 % at 2 yrs Stroke 2001;32:

93 Urinary incontinence –poor prognosis sign after stroke
Treatment ; detrusor hypereflexia : scheduled voiding ,fluid restriction,anticholinergic drugs avoid foley catheter placement to lower risk of nosocomial infection

94 4.2 urinary tract infection
- 11% of stroke pts. followed 3 months(only 1% serious med complication) - foley catheter placement & duration related to risk of UTI - most common organism : Escherichia coli Circulation1994;90: Stroke1998;29:

95 catheter related UTI may asymptomatic and lack of present peripheral WBC
related-catheter UTI found WBC in urine >10 /HF only 37 % urine culture important in Dx catheter related UTI Arch Intern Med2000;160:

96 4.3 Sexual dysfunction -related to; fear of stroke recurrence physical disability medication effect sensory deficit

97 2 months of stroke ,40% of pts
2 months of stroke ,40% of pts. express moderate or complete dissatisfaction with their sex lives male; libido,ejaculatory dysfunction,impotence female; decline vaginal lubrication> orgasm failure in case of decline libido should exclude depression or hormonal deficiency J Urol2001;165:

98 5.Gastrointestinal complication
5.1 GI bleeding 3% serious medical complication GI prophylaxis recommended for intensive care unit patients with a central nervous system process but not as routine therapy for all stroke pateints NPO patients – reasonable Stroke 1998;29: Am J gastroenterol 1995;90:

99 6. Miscellaneous complications
6.1 falls -hip fracture 2-4 times more common in stroke patients (secondary from fall)

100 -hospitalized stroke pts.
have skeletal unloading secondary to bed rest & disused of paretic limb; predisposing to bone resorption

101 6.2 skin breakdown - pressure sore ; 20% of stroke pts. - prevention ;early mobilization, frequent turning, use specialized alternating pressure mattress close surveilance

102 6.3 depression post stroke depression incidence = % risk factor for post stroke depression; 1. female gender 2. higher disability scores 3 . Prior hx of depression Curr Opin Neurol 2002;15:85-89

103 depression at 3 months correlated with poor outcome at 1 year
Match for initial functional ,outcome Pts whose depression remit have better outcome at 3 and 6 months - treatment; SSRI Stroke 1998;29: Stroke 2001;32:

104 Rehabilitation Early initiation of rehabilitation services may increase the potential for improved functional outcome Early rehabilitation is key for recovery Early mobilization also prevents: Deep venous thromboses and pulmonary emboli Decubitus ulcers Contractures Malnutrition Pneumonias UTI
