There are 2 kinds of surgical approaches to unruptured anterior communicating artery aneurysm (Acom an): the pterional and interhemispheric approach. Currently, the thoice of approach depends on the surgeon's preference and experience. In our study, we compared the interrelationship between appropriate surgical approach and dome projection among the following 3 groups: anterior/inferior, superior, and posterior projections. The results showed only aneurysms with anterior/inferior dome projection were suitable for the pterional approach. However, the interhemispheric approach was preferable for aneurysms with all other projections except for anterior/inferior projection. Surgeons should be familiar with both approaches so they we can select according to dome projection of Acom an.
