Clinical Stroke Flashcards
exam 2
two major stroke subtypes
- ischemic
- hemorrhagic
putamenal hemorrhage
- located to the putamen
- may have sudden onset with smooth preogression of deficit
- focal deficit
- headache
- nausea/vomiting
- decreased level of consciousness
intracerebral hemorrhage
intracerebral hemorrhage tx.
no specific therapy
- Supportive; BP management
CN III is close to which artery?
Posterior Communicating A.
- sudden onset headache
- stiff neck
- photophobia
- nausea/ vomiting
- transient loss of consciousness
subarachnoid hemorrhage
subarachnoid hemorrhage is the worst headache of my life?
Forget that term!
subarachnoid hemorrhage will have a “ ____ bleed”
and lumbar puncture shows
sentinal bleed and shows red blood cells and xanthochromia
major concerns of subarachnoid hemorrhage
- rebleeding
- vasospasm
- seizure
- increased intracranial pressure
a tangle of abnormal vessels which form an aberrant communcation between arterial and venous systems
arteriovenous malformation (AVM)
AVM tend to have thinned or thick walled vessels?
thin!!!!
sings of AVM
- any focal deficits
- cranial bruits
AVM symptoms
- subarachnoid hemorrhage
- intraparenchymal hemorrhage
- seizures
- headaches
AVM tx.
obliteration of malformation by:
- surgical excision
- endovascular thrombosis
- radiation- including Gamma knife
lipohyalinosis
small vessel disease
common mechanism of cerebral ischemia
- embolism
- decreased perfusion through a fixed stenosis
small vessel disease is associated with
HTN, DM and probs cholesterol
lacune
small vessel disease
not all small strokes are due to a small vessel disease
true
what can be used to identify strokes?
- transcranial ultrasound
- carotid ultrasound
- angiogram
medical managment for carotid artery stenosis
risk factor control
antiplatelet agents
HMG-CoA reductase inhibitor
common cardiac condition associated with cerebral embolism
atrial fibrillation
hypercoagulable states commonly associated with
cancer
plumbing approach
revascularization
neuroprotection
preventing damage from ischemic cascade
magic hour
refers to that is the maximum time the patient to be seen by the doctors
t-PA has any benefits for Ischemic stroke?
