stroke Flashcards
most common risk factors for arterial ischemic stroke (AIS) in children
congenital heart disease
acquired heart disease
arteriopathies ( transient cerebral arteriopathy, arterial dissection, moyamoya syndrome, vasculitis)
infection
hematologic (sickle cell, prothrombotic states)
metabolic
oncologic
risk factors for neonatal strokes
cardiac disorders hypercoaguable conditions infections trauma medications maternal disorders perinatal asphyxia
in the neonate, stroke most commonly presents with
focal seizure
other s/s
decreased responsiveness
focal weakness
for strokes, children are more likely to present with
focal neuro deficits such as hemiparesis
aphasia
visual disturbances
headache
in neonates and children, _____ are the most common presenting sign of sinus venous thrombosis (SVT)
seizures
when is Sinus venous thrombosis (SVT) most commonly seen?
more than half present in the first 6 months of life with the neonatal period being the most common
if a carotid or vertebral dissection or SVT is a consideration, _______, should be performed (imaging)
CTA/MRA or venogram
what imaging is useful to evaluate for metabolic causes of stroke
MR spectroscopy
AHA class 1 stroke recommendations
supportive management:
supplementing coagulation factors in coag disorders
Replacing platelets in those with intracranial hemorrhage
ventricular drainage for hydrocephalus
AHA class II stroke recommendations
treat dehydration treat anemia use rehab sources give folate or vit B to those with a MTHFR mutation and an abnormal homocysteine level evacuate hematoma that elevates ICP
General stroke management
Support ABCs
Neuroprotection:
-prevent fever
-maintain normoglycemia
-maintain normovolemia
-HOB flat to promote cerebral perfusion unless concern for ICP
ASA 3-5 mg/kg/day for recurrent stroke prevention (proven to be as effective as warfarin in kids)
- Consider risk of Reye syndrome first - at risk following varicella and other viral infections.
for extracranial dissection or cardioembolic stroke - anticoagulation with heparin or low molecular weight heparin can be initiated acutely..
do you give TPA in children
it is increasing in use but it is not FDA approved for use in children
imaging for dissection
CTA or MRA
