Cerebrovascular Disorders Flashcards
Acute deficits, specific to location of occlusion
Vertebrosailar occlusion
Acute onset N/V, disequilirbium, HA, LOC, may have focal deficits Surgery
Intracerebral hemorrhage
Progresses to subarchnoid hemorrhage. Mostly asymptomatic until rupture, focal deficits prior to rupture. Most found on anterior circle of willis, cerebral artery and internal carotid
Intracranial aneurysm
-Obstruction of small arteries in basal ganglia, pons, cerebellum, internal capsule, thalamus -Pure motor, or pure sensory deficit contrallaterally. Ipsilateral ataxia. Dysarthria w/ hand clumsiness Partial/complete resolution in 4-6 weeks
Lacunar stroke
Acute focal neuro deficits which resolve w/in 24hrs. Dysphagia, weakness, etc. 1/3 will go on to have stroke
TIA
Focal deficits, sz’s, hemorrhage, obtundation Occurs at arterial bifurcations. Often multiple.
AV malformation/ Saccular (Berry) aneurysm
Acute onset, minimally progressing symptoms. Contralateral hemiplegia, hemisensory loss.
Carotid Artery Obstruction
Sudden unilateral loss of vision which returns after a few seconds to minutes -Tx: CCB, ASA, carotid angioplasty, anticoagulation
Amaurosis fugax
Acute, “worst HA of life,” obtundation, focal deficits often ABSENT. Nuchal rigidity.
Subarachnoid hemorrhage
Supraclavicular bruits, unequal radial pulses and BPs, dizzy/vertigo, slurred speech, hemiparesis, syncope with arm exertion -Localized stenosis/occlusion of subclavian artery–>retrograde flow in vertebral artery
Subclavian steal syndrome
