Stroke And Hemorrhage Flashcards
Sudden onset “worst headache of my life” could indicate a ____________ ___________.
Subarachnoid hemorrhage
A necrotic region of tissue is called an _______.
Infarct
An abrupt incident of vascular insufficiency is called a ______.
Stroke
The region surrounding the area of permanent tissue damage and that may survive if treated rapidly and appropriately is called the ________.
Penumbra
Name 2 types of an occlusive/ischemic stroke.
Thrombotic
Embolic
Which type of occlusive stroke has a clot that forms locally over an atherosclerotic lesion and often has prodromes - vasospasms and partial occlusion aka transient ischemic attacks.
Thrombotic
Which type of occlusive stroke has a blockage by thrombi formed elsewhere? The thrombus detaches, travels and lodges in an artery, often without prodromes.
Embolic
Watershed Infarct: hypoxia due to insufficient _____ ______.
Blood supply
A classic example of a transient ischemic attack syndrome is transient ___________ _________ or amaurosis fugax, typically caused by emboli that detach from a plaque in the internal carotid artery, enter the ophthalmic artery, and render the retina temporarily ischemic.
Monocular blindness
Necrosis of the brain tissue is known as ____________ ________.
Liquefactive necrosis
Patient presents with contralateral hemiparesis and sensory loss predominantly in the face and upper extremity - most likely, which artery has the stroke affected?
The Middle Cerebral Artery (MCA)
If a patient has suffered a stroke and their speech is fluent, but makes no sense, which region of the brain is most likely affected?
Wernicke
If a patient has suffered a stroke and their speech is not fluent, but it makes sense, which region of the brain is most likely affected?
Broca
Stokes involving the MCA:
\_\_\_\_\_\_\_ strokes: Pure motor pure sensory Isolated symptoms Monoparesis Isolated sensory loss
Lacunar
Stroke patient has main symptoms of:
Contralateral hemiparesis predominantly in the lower extremity
Contralateral sensory loss predominantly in the lower extremity
Urinary incontinence
Which artery is most likely affected?
Anterior Cerebral Artery
Stroke patient has symptoms of vertigo, ataxia, ipsilateral sensory loss in the face, and contralateral hemiparesis and sensory loss in the trunk and limbs. Which artery is most likely affected?
The Vertebral-Basilar system
The posterior inferior cerebellar artery (PICA) supplies:
The inferior surface of the cerebellar hemisphere
And
The lateral medulla
Occlusion of the posterior inferior cerebellar artery causes lateral medullary syndrome or ________ syndrome.
Wallenberg
Strokes involving the _________ ________ ______ have main symptoms of:
Gaze paralysis
Visual field defects
Hemianopsia - eye deviates toward the side of the lesion to compensate “eye looks toward lesion”
Contralateral sensory loss
Posterior cerebral artery
These types of hematoma s are lens shaped
Epidural hematoma
These hematoma’s are often seen in shaken baby syndrome, alcoholics, and the elderly. Predisposing factors include brain atrophy, shaking, whiplash.
Subdural hematoma
These hemorrhage’s are due to ruptured berry aneurysms. Commonly associated with adult polycystic kidney disease, Ehlers-Danlos syndrome, and Marfan’s syndrome.
Subarachnoid hemorrhage
