Conference paper


Many approaches have been used in surgery on aneurysms of the anterior communicating artery (ACoA), but currently these diverse approaches can be subdivided into two main groups: an interhemispheric approach using a bifrontal craniotomy, and a pterional approach using a frontotemporal craniotomy. Although we have tried various surgical approaches, the majority of operations were performed using the interhemispheric approach, which we have come to believe is the safest and the most effective method for surgical treatment of such aneurysms.
