The anterior circulation supplies blood flow to what general areas?
Eyes, cerebral cortex, insula, hippocampus, basal ganglia, internal capsule.
Distribution of anterior spinal artery?
Ventral 2/3 of spinal cord, medial medulla.
Paralysis, loss of protopathic sense, and ipsilateral tongue paralysis are indicative of what artery lesion?
Anterior spinal artery.
Distribution of PICA?
Dorsolateral medulla & pons, medial cerebellum, cerebellar cortex.
Vertigo, balance problems, cerebellar signs, loss of protopathic facial sense, and hoarseness are indicative of what artery lesion?
PICA
Distribution of AICA?
Inferior cerebellar cortex, dorsolateral pons.
Cerebellar signs, facial paralysis, ipsilateral hearing loss, and loss of protopathic facial sense are indicative of what artery lesion?
