Large Vessel Stroke
The time goal for a large vessel occlusion stroke from the time of arrival to puncture.
< 60 minutes
The most common cause of a spontaneous hemorrhagic stroke.
Uncontrolled hypertension
The most common thrombolytic used to treat ischemic strokes within 3 to 4.5 of stroke symptom onset.
Intravenous Alteplase
The part of the brain that all cranial nerves originate from.
Brainstem
The two arteries which run up the cervical spine and merge to become the basilar artery.
Vertebral arteries
The term of ignoring or neglecting one side of the body.
Agnosia
The color of acute blood shown on the plain CT brain scan.
White
The most effective treatment for removal of clots in the large vessels of the brain.
What is Mechanical Thrombectomy
A patient presenting with left gaze deviation and right hemiplegia may have a stroke in this large vessel in the brain.
Left Middle Cerebral Artery
"Dizziness Plus" helps to identify posterior infarctions. Name at least 2 symptoms that can help identify posterior infarctions when some is dizzy.
Diplopia, Dysarthria, Ataxia, Nausea/Vomiting
The advanced imaging used to diagnose a large vessel occlusion.
CT Angiogram/CT Perfusion
The most common reason for spontaneous subarachnoid hemorrhage.
Ruptured aneurysm
True or False: Alteplase works best on large vessel occlusion strokes.
False
The type of stroke that describes areas of the brain that are sensitive to periods of hypoperfusion/low blood pressure.
Watershed
Location of infarction that presents with hoarseness, hiccups, nystagmus, nausea, body temperature dysregulation, dizziness, ataxia, and swallowing difficulties.
brainstem
Wallenberg Syndrome
The scoring system used post mechanical thrombectomy that grades the amount of perfusion restored to the previously blocked area of the brain.
TICI Score (0, 1, 2a, 2b, 3)
The recommended SBP parameter for hemorrhagic strokes.
SBP 130-150 mmHG
The approximate amount of brain cells damaged per minute during a stroke.
1.9 million
The cerebral artery involved in the stroke that presents with dizziness, nausea & vomiting, nystagmus and most likely to result in locked-in syndrome.
Basilar Artery
The percentage of strokes that originate from the posterior circulation.
20-40%
The term for stroke signs/symptoms that help identify posterior infarctions originating for the cortex of the brain.
Cortical Signs: Agnosia, Aphasia, Ataxia, Visual Changes
The oral medication used to prevent vasospasms in SAH patients.
Nimodipine
The 3 ways to treat an ischemic stroke patient.
Tissue Plasminogen Activator, Mechanical thrombectomy, & permissive hypertension
The spider like thin, delicate middle layer surrounding the brain, where major cerebral blood vessel lies.
Arachnoid Layer
The clinical tool used to differentiate a central vs peripheral cause to dizziness.
HINTS (head impulse, nystagmus, & test of skew) Exam
