[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.
