Distal anterior cerebral artery aneurysms: bifrontal basal anterior interhemispheric approach

The advantages of the bifrontal basal anterior interhemispheric approach were the following: (a) It provided the shortest and a direct trajectory to the aneurysm. (b) Proximal control of the parent A2 vessels could be easily achieved. (c) Release of cerebrospinal fluid from basal cisterns could be done, if necessary. (d) There was a minimal distortion of or traction over the aneurysm.
