Abstract

Background

Vertebral artery dissection is a potential cause of posterior circulation ischemia that requires high-spatial-resolution imaging. The present study was conducted to determine spectrum of MRI imaging in vertebral artery dissection.

Materials and Method

The present study was conducted on 64 cases of vertebral artery dissection of both genders. All participants were imaged by1.5 T super conducting magnetic resonance imager. The site of dissection was classified as V1 (prevertebral segment), V2 (intertransverse segment), V3 (atlantoaxial segment) and V4 (intradural/intracranial segment) using standard method of classification.

Results

Out of 64 patients, males were 34 and females were 30. Dizziness was present in 34, gait instability in 38, headache in 42 and altered mental status in 50. The difference was non-significant (P> 0.05). VI was seen in 1, V2 in 7, V3 in 36 and V4 in 20. The difference was significant (P> 0.05). Posterior circulation infarct was present in 25, cerebellar infarction in 11, cerebellar and medullary infarct in 9, occipital infarct in 12, subarachnoid hemorrhage in 2 and solitary lateral medullary infarct in 5.

Conclusion

Most common MRI finding was posterior circulation infarct, cerebellar infarction, cerebellar and medullary infarct, occipital infarct, subarachnoid hemorrhage, solitary lateral medullary infarct.
