Cerebral angiography revealed that hypoplasia of the A1 portion of the anterior cerebral artery is more frequent in patients with aneurysms of the anterior communicating artery than in those with aneurysms of other intracranial arteries. As for the hypoplasia of the A1, the angiographic findings corresponded to the surgical findings in 86.9% of all the patients. In patients with anterior communicating artery aneurysms, the incidence of hypoplasia of the A1 portion was about 3 times higher on the right side than on the left side.
脑血管造影显示，前交通动脉动脉瘤患者大脑前动脉A1段发育不全的发生率高于其他颅内动脉动脉瘤患者。至于A1段发育不全，在所有患者中，血管造影结果与手术结果相符的比例为86.9%。在前交通动脉动脉瘤患者中，A1段发育不全的发生率右侧约为左侧的3倍。
