前交通动脉(ACoA)是颅内动脉瘤的好发部位,以往是根据尸体解剖对ACoA 进行显微解剖分析,本文作者则对一组ACoA 动脉瘤患者的术中所见进行了分析。作者收集了从1985年至1990年经造影证实并手术了的ACoA 动脉瘤共134例,其中46例(34.3%)有ACoA 解剖变异,称为Ⅰ组:另择46例无解剖变异者组成Ⅱ组。此外,根据手术入路的不同又将每组分成三个亚组:即经侧裂入路组;纵裂前部入路组和纵裂底部入路组。在有ACoA 解
The anterior communicating artery (ACoA) is a predilection site for intracranial aneurysms. In the past, microanatomical analysis of ACoA was performed based on autopsy. The authors analyzed the results of intraoperative findings in a group of ACoA aneurysms. The authors collected a total of 134 ACoA aneurysms confirmed by angiography from 1985 to 1990, of which 46 (34.3%) had ACoA anatomical variations and were referred to as Group I: Alternative 46 patients without anatomical variations included II. group. In addition, depending on the surgical approach, each component will be divided into three subgroups: the lateral schizophrenic approach group; the longitudinal anterior approach group and the longitudinal approach approach group. In the ACoA solution
