Abstract
Objective To investigate the relationship between classical trigeminal neuralgia ( CTN ) and vertebral artery dominance (VAD).Methods The clinical data of CTN patients (n =384) and None-CTN (N-CTN) patients ( n =384 ) were collected; and the score of CTN patients ' symptom was evaluated by Frighetto standard, the diameter of bilateral vertebral artery and the bending length of basilar artery ( BL) were measured;and record the incidence , pain degree and the side difference of VAD and CTN were analyzed .Results The incidence of VAD was significantly different between CTN (61.46％)and N-CTN group(49.74％)(P<0.05).In CTN group, the incidence of right pain was significantly higher than that of the left side (P<0.05).The ratio of left dominance in CTN group and N-CTN group were significantly higher than right .VAD is often find in left side ( P<0.05);in the patients of VAD, the incidence of basilar artery curvature was 75.42％, BL was about (3.72 ±1.47) mm in CTN group, however, in N-CTN group, the incidence of basilar artery curvature is 59.68％, BL was about (2.39 ±1. 08)mm, which was statistical difference between the two groups (P<0.05).There were 292 cases in the 427 VAD patients which the basilar artery was tortuous , there were 246 cases which the basilar artery curved in the contralateral side of the dominant, accounting for 84.25％.The symptom score of CTN patients had significantly different during the difference level of bilateral vertebral artery;and the symptom score of CTN patients also had significantly different during difference level of basilar artery curvature .There was a positive correlation between CTN scores and vertebral artery diameter (r=0.341, P=0.001) in CTN patients, which was positively correlated with BL (r=0.134, P=0.001).Conclusions The incidence of VAD is higher in CTN group than that in N-CTN group, and the pain occured more often in the contralateral side of VAD .The greater the difference of VAD diameter is , the greater the degree of basilar artery curvature is , and the higher the score of CTN patients is .关键词
