摘　　要：目的:探讨永存颈内-基底动脉吻合变异各类型与动脉瘤发生风险的相关性研究。方法:回顾性分析93例永存颈内-基底动脉吻合变异患者的多排螺旋CT血管造影(MSCTA)资料及临床资料,将其作为研究组,并纳入同期120例MSCTA检查患者作为对照组,并筛选出两组中动脉瘤患者。通过皮尔逊卡方检验统计两组之间动脉瘤发生率差异性,以及各类型永存颈内-基底动脉吻合变异患者中动脉瘤发生率的差异性。结果:永存颈内-基底动脉吻合变异患者93例,合并动脉瘤患者为20例,发生率为21.5%,具体类型及其例数为永存三叉动脉(17/79),永存舌下动脉(2/6),永存寰前节间动脉(1/8)。永存动脉出现动脉瘤6例,除永存动脉外头颈部其他动脉出现动脉瘤12例,另外2例为永存动脉与其他动脉同时出现动脉瘤。研究组与对照组之间动脉瘤发生率差异有统计学意义(P<0.05),但研究组中头颈部其他动脉的动脉瘤发生率与对照组无明显差异(P>0.05)。永存颈内-基底动脉各类型之间动脉瘤的发生率无明显差异(P>0.05)。结论:永存颈内-基底动脉吻合变异增加动脉瘤发生风险,但并不会增加永存动脉以外头颈部其他动脉发生动脉瘤的风险,各类型永存颈内-基底动脉吻合变异之间动脉瘤的发生率无明显差异。Objective:The purpose of this study was to investigate the correlation between different variation types of persistent internal carotid-basilar artery anastomosis variation and the occurrence of aneurysms.Methods:The MSCTA images and the clinical data of 93 patients with persistent internal carotid-basilar artery were retrospectively analyzed,and divided as experimental group.120 patients examined by MSCTA were randomly selected as the control group.Patients with aneurysms in the two groups were detected and recorded.Pearson's Chi-square test was used to test the difference of aneurysm incidence between the two groups and the incidence difference in each type of persistent internal carotid-basilar artery anastomosis.Results:There were 93 cases of persistent internal carotid-basilar anastomosis,including 79 cases with persistent trigeminal artery(PTA),6 cases with persistent hypoglossal artery(PHA)and 8 cases with proatlantal intersegmental artery(PIA).20 cases of aneurysms(21.5%)were identified,including 17 cases with PTA,2 cases with PHA and 1 case with PIA.Aneurysms occurred in the persistent artery itself were 6 cases and occurred other arteries were 12 cases.In addition,aneurysm occurred in both the persistent artery and the other arteries were 2 cases.The difference of aneurysm incidence between persistent internal carotid-basilar anastomosis group and control group was statistically significant(P<0.05).Incidence of aneurysm on other arteries in the experimental group compared with control group was not significant(P>0.05).The difference of aneurysm incidence in each types of persistent internal carotid basilar artery was not significant(P>0.05).Conclusion:Persistent carotid-basilar artery anastomosis increasees the occurrence risk of aneurysms,but not increase the risk of aneurysm in other arteries.There was no significant difference in the incidence of aneurysms in each types of persistent internal carotid basilar artery.
