摘要
目的探讨囊状动脉瘤与颅内动脉血管分叉的角度关系。方法随机选取后交通动脉显影(包括胚胎型)且有动脉瘤者30例作为试验组,另选取后交通动脉显影(包括胚胎型)且无动脉瘤者30例作为对照组,均予三维(3D)脑血管造影观察颈内动脉后交通动脉段及后交通动脉间夹角,比较2组血管分叉的角度差异。结果试验组主流出道与流入道偏角、小分支与流入道偏角及分支夹角均大于对照组,差异均有统计学意义(P<0.01)。结论动脉瘤的发生发展与颈内动脉后交通动脉分支段和后交通动脉之间夹角变大有关。
Objective To explore the relationship of saccular aneurysm and the angle of intracranial artery bifurcation. Methods Selected the posterior communicating artery imaging and aneurysm in 30 cases as test group, Selected the pos- terior communicating artery imaging and no aneurysm in 30 cases as control group. Studied the angle of internal carotid artery and posterior communicating artery by 3 D cerebral angiography. Compared the angle difference between two groups of vascular bifurcation. Results The angle of the inflow tract and mainstream debut, the angle of small branches and inflow tract, and branch angles of test group were greater than control group, there were significant difference ( P 〈 0.01 ). Conclusion The occurring of aneurysm is associated with the angle of internal carotid artery and posterior communicating artery.
