Anterior interhemispheric approach for distal anterior cerebral artery aneurysm surgery: preoperative analysis of the venous anatomy can help to avoid venous infarction

摘要

Background. The anterior interhemispheric approach is a well-known operative technique for a distal anterior cerebral artery (ACA) aneurysm. However, a frontal parasagittal bridging vein is occasionally sacrificed in this approach, creating a risk of postoperative venous infarction.
