ABSTRACT
The authors reviewed angiographic findings of 96 cases of ruptured anterior communicating artery aneurysms that were operated at the Department of Neurosurgery of Hanyang University Hospital from Jan. 1986 to June 1990. The results were summarized as follows ; 1) Asymmetricity of caliber of A1 was observed in 71.9%(69/96) and which was 3 times more frequent than that of reported incidence of control group(2~23%). 2) The incidence of predominance of left A1 was 54.2%(53/96) and that of right A1 was 17.7%(17/96). Among them, predominant A1 was operated as afferent artery of aneurysm in 94.2%(65/69). 3) Of 69 cases in which a unilateral A1 showed predominance, the direction of aneurysm was opposite to the side of predominant A1 in 66.7%(46/69) and ipsilateral to the predominant A1 in only 2.9%(2/69). 4) Above findings suggest that it is desirable to approach the anterior communicating artery aneurysm via the side of predominant A1 when the direction of aneurysm is uncertain on cerebral angiogram.
