CVA Flashcards
Most common sites of CVA lesions
origin of the common carotid artery
middle cerebral artery (main bifurcation)
junction of vertebral arteries and basilar artery
middle cerebral CVA
most common stroke
contra hemiplegia (UE>LE)
loss of UE and facial sensation
often includes homonymous hemianopsia
injury in L hemisphere may cause aphasia and apraxia
if main stem of middle cerebral artery occluded, global aphasia may occur
anterior cerebral CVA
rarely involved
contra hemi and loss of sensation
LE>UE
can result in mental confusion, aphasia, contra neglect if extensive damage to dominant side
posterior cerebral CVA
persistent pain syndrome may occur
or
contra loss of pain and temp sensory
may include:
homonymous hemianopsia
aphasia
thalamic pain syndrome
vertebral basilar CVA
often fatal due to edema
if patient survives and pons affected, patient may have quadraparesis and bulbar palsy
“locked in state”
only able to communicate with eye blinks
other sx may include: vertigo coma diplopia nausea dysphagia (difficulty swallowing) ataxia
anterior inferior cerebellar CVA
unilateral deafness
unilateral Horner’s syndrome
loss of sweating
ataxia
vertigo
nystagmus
contra loss of pain and temp sensory
paresis of lateral gaze
superior cerebellar CVA
severe ataxia
dysarthria (loss of muscle articulation control)
dysmetria
contra loss of pain and temp sensory
posterior inferior cerebellar CVA
Wallenerg's syndrome vertigo nausea hoarseness dysphagia ptosis decreased sensation ipsi face and contra torso/limbs
may include Horner’s syndrome
