Clinical Stroke Flashcards
exam 2 (27 cards)
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
