In addition, the sometimes inevitable temporary clipping of perforating vessels seems to play a significant role with respect to later neuropsychological disturbances. Since modern aneurysm surgery is performed in the acute phase shortly after the hemorrhage, the findings reported in the present work are, according to my...
