[Clinical significance of vertebral artery MRA to vertebral artery type of cervical spondylosis' diagnosis and treatment].

OBJECTIVE
To study clinical significance of vertebral artery magnetic resonance angiography (MRA) to vertebral artery type of cervical spondylosis' diagnosis and treatment.


METHODS
There were two groups in the study, which were observation group and control group. There were 53 patients in observation group,including 19 males and 34 females,with a mean age of (52.51 +/- 11.29) years. There were 30 subjects in control group,including 10 males and 20 females,with a mean age of (48.11 +/- 12.21) years. Based on the vertebral artery MRA picture,the course and caliber of vertebral artery were compared between two groups.


RESULTS
The abnormal incidence of course and caliber of vertebral artery in observation group was higher than that of control group, which had statistic difference (P=0.000). Furthermore, the patterns of abnormal course and caliber of vertebral artery in observation group were complicated and diverse, but the regional circuity and stegnosis was the most common pattern,about 47.18%(25/53). The cause of circuity and stegnosis was vertebra Gu-Cuofeng,about 43.41% (23/53).


CONCLUSION
The vertebral artery MRA provides a guidance for the diagnosis of abnormal course and caliber of vertebral artery in vertebral artery cervical spondylosis.
