pestana: neuro surg Flashcards
time table of vascular problems vs brain tumors vs infectious problems vs degenerative dz vs metabolic
vascular: sudden onset
metabolic: rapidly
infectious: days-weeks
brain tumor: months
degenerative: years
characteristics of brain tumor
constant
progressive
severe HA
worse in morning
TIAs most commonly affect where
stenosis of internal carotid
or
ulcerated plaque at carotid bifurcation
what can minimize stroke after TIA?
elective carotid endartectomy
angiplasty and stent can be done if filter put in 1st to rpevent embolization of debris to brain
ischemic strokes longer than ___ hours are not amenable to revascularization procedures and meds
3
what imaging to assess for stroke
CT
med treatment for stroke
tPA (best within 90 min)
hemorrhagic stroke seen in which population
uncontrolled HTN
does subarachnoid bleeding have neuro defects?
not always but hope that they do so it’s recognized!
subarachnoid bleeding comes from what pathology?
intracranial aneurysm
work up of subarachnoid bleed
- CT
2. arteriogram- aneurysm
therapy choices for subarachnoid hematoma
clipping- surgery
endovascular coiling- radiology alternative
most intracranial tumors primary or metastatic?
metastatic
where do brain mets come from originally?
- lung
then: breast, melanoma
symptoms of brain tumor
space occupying
HA, worse in morning
ICP: blurred vision, papilledema, vomiting, brady, hypo
ICP is first treated with
high dose steroids
cranipharyngioma symptoms
short for age
bitemporal hemianopsia
calcified lesion above sella
pituitary apoplexy
bleeding into pituitary tumor –> destruction of pituitary
tumors of pineal gland cause
loss of upper gaze (sunset eyes- Parinaud syn)
brain tumors in kids are where
posterior fossa
top two most common brain tumors in kids
- medulloblastoma
2. ependymoma
medulloblastoma symptoms
cerebella: stmubling, truncal ataxia
trigeminal neuralgia pain lasts how long
60 seconds
reflex sympathetic dystrophy happens sever months after
crushing injury
reflex sympathetic dystrophy symptoms
constant, burning, pain, sensitive
cold, cyanotic, moisit
reflex sympathetic dystrophy diagnosis and cure
diagnosis: sympathetic block
treat: surgical sympathectomy
