为了解Willis环变异与动脉瘤的关系，对44例Willis环合并动脉瘤进行了肉眼观察。动脉瘤系列中的变异发生率显着高于无动脉瘤的对照圈。大脑前动脉近端段不对称与前交通动脉瘤之间存在明确的相关性，而后交通动脉不对称与颈内动脉-后交通动脉交界处的动脉瘤之间存在相关性。通过血流动力学的变化，Willis环的变异在脑动脉瘤的发生发展中起一定作用。
In order to obtain information about the relationship between variations in the circle of Willis and aneurysms, 44 complete circles of Willis with aneurysm were studied macroscopically. The incidence of variations was significantly higher in the aneurysm series than in the control circles without aneurysm. There was a definite correlation between asymmetric proximal segments of the anterior cerebral artery and aneurysms of the anterior communicating artery, and a tendency to correlation was found in the case of asymmetric posterior communicating arteries and aneurysms on the internal carotid artery-posterior communicating artery junction. Through hemodynamic changes variation in the circle of Willis apparently plays some role in the development of cerebral aneurysms.
