| 摘 要： | 目的:探讨大脑前循环动脉形态参数与前交通动脉瘤（AcomAA）的相关性。方法:收集我院AcomAA的患者CTA 73例作为AcomAA患者组和颅脑CTA正常的患者85例作为对照组。采用独立样本t检验，比较AcomAA患者同侧与对侧以及对照组大脑前循环动脉的形态学参数（血管直径，血管直径比值和血管分岔角度）。结果:AcomAA患者组同侧的ICA直径大于对侧的ICA直径及对照组的平均ICA直径（P=0.005，P<0.001）。AcomAA患者的对侧ICA直径与对照组的平均ICA直径无统计学意义（P=0.084）。AcomAA患者的同侧A1直径大于对侧A1直径和对照组的平均A1直径（P<0.001，P=0.002）。AcomAA患者对侧A1的直径小于对照组的平均A1直径（P<0.001）。AcomAA患者的同侧M1直径与对侧M1直径及对照组的平均M1直径无统计学差异（P=0.657，P=0.567）。AcomAA患者对侧的ICA/A1比值高于同侧及对照组的平均ICA/A1比值（P<0.001，P<0.001）。AcomAA患者同侧ICA/A1比值与对照组的平均ICA/A1比值无统计学差异（P=0.958）。AcomAA患者同侧A1/A2比值高于对侧A1/A2比值和对照组平均A1/A2比值（P<0.001，P<0.001）。AcomAA患者的对侧A1/A2比值小于对照组的平均A1/A2比值（P<0.001）。AcomAA患者组同侧A1-A2分岔角度最小（90.80±19.98），对照组平均角度最大（115.58±17.41），两两比较均有统计学差异（P<0.001，P<0.001，P=0.042）。结论:大脑前循环动脉的形态学可能与AcomAA具有相关性。

| Abstract: | Objective: To investigate the correlation between the morphological parameters of anterior cerebral circulation artery and anterior communicating artery aneurysm(AcomAA). Methods: 73 patients with Acom AA were collected as the AcomAA patient group and 85 patients with normal craniocerebral CTA as the control group. Independent sample T-test was used to compare the morphological parameters of anterior cerebral circulation arteries(vessel diameter, vessel diameter ratio and vessel biforking Angle) of the ipsilateral and contralateral AcomAA patients and the control group. Results: ICA diameter on the ipsilateral side of AcomAA patients was greater than that on the contralateral side and average ICA diameter on the control group(P=0.005, P<0.001). There was no statistical significance between the contralateral ICA diameter of AcomAA patients and the mean ICA diameter of the control group(P=0.084). The ipadal A1 diameter of AcomAA patients was larger than the contralateral A1 diameter and the average A1 diameter of the control group(P<0.001, P=0.002). The contralateral A1 diameter of Acom AA patients was smaller than the average A1 diameter of the control group(P<0.001). There was no statistically significant difference between the ipsilateral and contralateral M1 diameers of AcomAA patients and the average M1 diameers of the control group(P=0.657, P=0.567). ICA/A1 ratio on the contralateral side of AcomAA patients was higher than the average ICA/A1 ratio on the ipsilateral side and control group(P<0.001, P<0.001). There was no statistically significant difference in ICA/A1 ratio between the ipilateral AcomAA patients and the mean ICA/A1 ratio in the control group(P=0.958). The ipilateral A1/A2 ratio of AcomAA patients was higher than the contralateral A1/A2 ratio and the average A1/A2 ratio of the control group(P<0.001, P<0.001). The contralateral A1/A2 ratio of AcomAA patients was lower than the average A1/A2 ratio of the control group(P<0.001). The ipsilateral A1-A2 bifurcation Angle of the Acom AA patient group was the smallest(90.80 ±19.98), and the average Angle of the control group was the largest(115.58 ±17.41),and pairwise comparison showed statistical differences(P<0.001, P<0.001, P=0.042). Conclusion: The morphology of anterior cerebral circulation artery may be correlated with AcomAA. |
