Vertebrobasilar Arterial Insufficiency, Part II

Neurological Examination Findings in Cases of Vertebrobasilar Infarct

By Brad McKechnie, DC, DACAN
A review of 52 cases of vertebrobasilar infarct was performed to ascertain the frequency and types of symptoms and signs that accompanied the reported cases of infarct (1-33). In last month's column the symptoms associated with vertebrobasilar infarct were reviewed. The following is a review of the reported neurological signs associated with vertebrobasilar infarct.

# Signs noted
19 Cerebellar signs: ataxia, dyssynergia, dysmetria, etc.
18 Rotatory nystagmus
17 Facial nerve palsy
15 Paresthesia, decreased pain in trigeminal distribution
12 Paresthesia, decreased pain in body
11 Tandem gait veering
11 Asymmetrical pupils
8 Ptosis
8 Babinski's sign
8 Palatal paresis
6 Confusion
6 Dysarthria
6 Decreased arm/leg strength
4 Diplopia
4 Decreased corneal reflex
4 Cranial nerve VI palsy
4 Hyperreflexia
4 Quadriplegia
4 Visual field loss
4 Tongue deviation
3 Hoarseness
3 Dysphagia
2 Decreased hearing
2 Tinnitus
1 Drowsiness
1 Decreased position sense
1 Cranial nerve IV palsy
1 Grasp, suck reflexes
1 Respiratory paralysis

Should the chiropractic physician suspect that a patient is suffering from vertebrobasilar infarct, a neurological examination would be in order to better ascertain the extent of neurological involvement. The anatomical basis for the most common symptoms and signs of vertebrobasilar infarct will be discussed in detail in this column's next installment.
