The history of a sudden severe headache,
nausea, vomiting and positive Meningeal
irritation sign, no focal neurologic deficit
sign with (without) impairment of consciousness is
highly specific for SAH. Uniformity bloody
CSF, increased ICP and globular subhyaloid
hemorrhage found by eyeground examination are
most suggestive of the clinical diagnosis. CT
scan is the routine test, and then make the
aetiological diagnosis.

治疗 treatment
原则:控制继续出血、防治迟发性脑血管痉挛、去除病因和防止复发。
Principles: To control continuous hemorrhage,
to prevent and cure cerebrovascular spasm, to
remove causes and prevent recurrence.
内科处理:①一般处理:监护、绝对卧床4-6周,保持安静,避免一切引起血压和颅内
压升高的诱因
,镇静、通便,补液,加强护理,营养支持,防止并发症;②降颅压;③防止
再出血;④防治迟发性血管
痉挛;⑤脑脊液置换疗法。
Medical treatment: ①general
treatment: monitor, absolute bed rest for 4-6
weeks, keep
quiet, avoid every cause that
induce increased blood and ICP, sedation,
purgation, fluid infusion,
intensive nursing,
nutritional support, to prevent complications; ②
to lower ICP; ③ to prevent
recurrent
hemorrhage; ④to prevent and cure tardive
cerebrovasular spasm; ⑤CSF replacement

TIA (transient ischemic attack)
By definition,
transient ischemic attack, TIA, is a recurrent
ischemia in the brain within a
briefer
periods, which produces neurologic deficits, and
the symptoms and signs resolve
completely ,
usually within several minutes to 1 hour, no more
than 24 hours.
Clinic Features
Most
occurs in those middle and old ages, higher in
male than in female.
TIA begins abruptly,
within a briefer periods, and resolves quickly
without any residual
deficit.
Recurrent,
stable symptom.
Risk factor: Hypertension,Dia
betesmellitus,Hypercholesterolemia, Heart disease.
Features of Internal Carotid Artery
System TIA
Frequent symptom:
contralateral monoplegia, accompanying with
contralateral facial to MCA
infarction or
watershed infarction between MCA and ACA.
Characteristic symptom:ophthalmic artery
crossed palsy, Horner sign crossing palsy,
sometimes
accompanying aphasia.
Possible
symptom:hemisensory disturbances, hemiablepsia.
Frequent symptom:vertigo, balance
disturbance.
Characteristic symptom:drop
attack,
transient global amnesia, binocular
vision disorder.
Possible symptom:dysphagia,
ataxia, conscious disturbance,perioral numbness,
ambiopia, crossed
paralysis.
Treatment
Objective:eliminate etiological
factor,prevent and decrease recurrence, protect
the function of
brain.
Etiological
treatment
Prophylactic drug treatment:
antiplatelet agents, anticogulant, angiotenic,
traditional Chinese
medicine, fluid expansion
drugs.
Neuroprotective agents
Cerebral Infarction
Cerebral infarction,
CI, other named as cerebral ischemic stroke, CIS,
is defined as a local
ischemic necrosis or
cerebro- malacia in the brain tissue due to
disorder of the cerebral blood
supply,
ischemia and hypoxia.
Common typers:cerebral
thrombosis, lacunar infarction and cerebral
embolism.
Cerebral Thrombosis
The
stem or cortical branches of the cerebral arteries
occur angiostenosis or obstruction because of
vascular lesion such as artherosclerosis,
arteritis and etc, which causes cerebral
thrombosis. The
occlusion of a blood
vessel interrupts the flow of blood to a specific
region of the brain, and
produces ischemia,
hypoxia, malacia, necrosis, focal symptoms and
signs that correlate with the
area of the
brain supplied by the affected blood vessel.
Pathogeny & Mechanism
Arterial canal
stenosis and thrombosis
osclerosis,most occur in bifurcation of the
vessal.
itis
logical
system
Vasospasm
Other:hyper-
APLA, pro C, pro S, etc.
Pathophysiology
Ischemic Penumbra: conservation the neuron in
the IP, is the key of treatment of acute cerebral
infarction.
Time Window
Reperfusion
Damage:means that recover the blood flow of the
brain after the time may
aggravate mechanism
is regard with free radical, overload of
intracellular Ca2+ in the
neuron,excitatory
amino acids,etc.
Clinical Features
General features: artherosclerosis is the main
etiological factor for the middle and old age,
vasculitis is the common factor for young
ones. Generally onset at a calm or rest time,
reach the
peak after 1~2 days. Majority have
clear consciousness. Part of them are preceded by
TIAs.
Clinical classification:
complete stroke, progressive stroke, reversible-
ischemic neurological deficit.
Clinical
Syndrome
Syndrome of Internal Carotid Artery
Occlusion:
homonymy monocular amaurosis
homonymy Horner sign

weaken,vascular murmur from cervical or ocular
region.
Occlusion of Middle Cerebral
Artery
Occlusion of stem: hemiplegia,
hemisensory- deficit and hemianopia, with
aphasia(dominant
hemisphere), may have
different level of conscious disturbance.
Occlusion of cortical branch : occlusion of
superior division results in contralateral
hemiplegia
that affects the hand, arm and
face,combined with Broca aphasia; inferior
division results in
Wernicke aphasia, anomic
aphasia and behavioral disturbance.
Deep
perforating branch: contralateral hemiplegia,
hemisensory deficit and subcortex
aphasia,sometimes with hemianopia.
Occlusion of Anterior Cerebral Artery
Occlusion of stem: If the occlusion afterwards
the communicating artery: contralateral hemiplegia
that mainly affect the face, tongue and the
lower limbs, lightly hemisensory deficit,retention
of
urine or urgency and psychiatric symptom.
Occlusion of cortical branch: The main symptom
is same as occlusion of stem.
Deep
perforating branch: Contralateral hemiplegia that
mainly affect the face, tongue and the
upper
limbs.
