N4410 (Intracranial Regulation - stroke &
seizure)- Questions with complete solutions
stroke
- ischemia to part of brain (by obstruction, etc)
- hemorrhage into brain that results in death of brain cells (ruptured aneurysms, cocaine)
- severity of loss of function varies according to location and extent of brain damage
circle of willis
a circle of arteries at the base of the brain that supply blood to the brain
stroke prevention
- management of modifiable risk factors, such as healthy diet, no smoking, and weight control
- management of chronic disease, such as a-fib, DM, carotid artery disease, etc
TIA (transient ischemic attack)
- episode of neurologic dysfunction without infarction of brain
- mini stroke
- big warning sign pt is at risk for stroke
- anti platelet drugs are used in pts with this related to atherosclerosis
statins
- used in the prevention of stroke for patients who have experienced a TIA in the past
- direct link to stroke risk
TIA surgical interventions
, - carotid endarterectomy
- transluminal angioplasty
- stenting
- left atrial appendage occlusion
thrombotic stroke
- the process of clot formation results in a narrowing of lumen, which blocks the passage of the
blood through the artery
- DM, HTN at risk
- most common
- TIA is warning sign
- subtle symptoms, collateral circulation might help
embolic stroke
- when a moving clot reaches an artery in the brain that is too narrow to pass through, it lodges
there and blocks the flow of the blood
- sickle cell and a-fib at risk
- second most common
- sudden onset, severe, symptoms and neuro deficits
hemorrhagic stroke
- a burst blood vessel may allow blood to seep into and damage brain tissues until clotting shuts
off the leak
- intercerebral or subarachnoid
