Objective To evaluate the ultrasonic diagnosis value of congenital variation of extracranial vertebral artery(VA).Methods The VA in 8557 patients with vertebra artery type of cervical spondylosis were examined by ultrasonography.The rate of the congenital variation of VA were analyzed.The vascular morphological changes and hemodynamics of the vertebral artery which involves the diameter,route,starting point,peak systolic velocity(PSV),end diastolic velocity(EDV) and resistance index(RI) were also observed.The blood flow parameters of patients with vertebral artery origin variation were statistically analyzed and compared to the control group.Results In the 8775 cases with doubtful vertebrobasilar insufficiency,the rate of abnormal entrance position into the transverse foramen was 6.8％ (581/8557),the rate in left side was 43.0％ (250/581),the rate in right side was 35.8％ (208/581),the rate in both sides was 21.2％ (123/581).The rate of original variation was 1.1％(99/8557),96.9％ (96/99),the rate of original variation in right side was 3.1％ (3/99).The vertebral artery diameter and intervertebral paragraphs in case group were less than the normal control group [starting segment:(3.0 ±0.7)cm vs (3.9 ±0.7)cm,intervertebral segments:(3.1 ±0.7)cm vs (3.7 ±0.6)cm],RI were greater than those in normal control group [starting segment:(0.72 ± 0.08) vs (0.68 ± 0.07),intervertebral segments:(0.69 ± 0.07) vs (0.65 ± 0.07),P ＜ 0.01 or P ＜ 0.05),and PSV,EDV of starting period of vertebral artery in the case group of were higher than the normal control group (RSV):(73 ± 22) cm/s vs (66 ± 22) cm/s,EDV (20 ±7)cm/s vs (20 ±6)cm/s,P＜0.01 or P＜0.05)],intervertebral PSV,EDV were lower than those in normal control group [RSV:(52 ± 15) cm/s vs (53 ± 14) cm/s,EDV (16 ± 5) cm/s vs (18 ± 6) cm/s,P ＜ 0.01 or P ＜ 0.05].Conclusions Ultrasonography is a rapid,non-invasive,and no radioactive method for the diagnosis of anomalous origin of vertebral artery.The original variation of VA which the vascular morphological and hemodynimics has often happened in the left side.
