“…In the present study seven indices were measured which were bifrontal, bicaudate, ventricular, huckman, evans, third ventricular, cella media. Bifrontal index is normally one third of the width of brain as reported by some authors [16,17,18]. In the present study, bifrontal index was found to be 0.30 which was similar with the findings reported by various authors.…”

“…The distances between the N and the cross points of the two trajectories on the surface of the skull in the forehead were measured (D N-BH-C and D N-BH-1/2CV ), respectively. The crosspoints were defined as the aim points and a bicaudate cerebroventricular index (CVI), the ratio of the width of the lateral ventricles to the width of the brain, at the level of the mid portion of the head of the caudate nucleus (normal value 15 ± 3%), 12) was established to determine whether the size of the ventricle and the height of the aim point were related.…”

The manual occipital ventricular puncture is a standard surgical procedure, but specific targeting has not received sufficient attention despite the experience of anatomical disorientation. This study tried to identify an exact site for the ideal trajectory with this method, especially in the sagittal plane, which avoids contact with the choroid plexus that may be the major source of complications. A total of 44 consecutive adult cases undergoing cerebrospinal fluid shunting through the occipital route for hydrocephalus were retrospectively reviewed for the following: correlations between burr hole site, direction of puncture, and location of the ventricular catheter based on postsurgical radiological studies; calculation of the ideal trajectory to place the catheter tip in the anterior horn of the lateral ventricle without contact with the choroid plexus through the standard occipital burr hole. In addition, the relationships between the location of the ventricular structure, the cranial base line connecting the nasion and inion, and the size of the ventricle were evaluated. Incorrect catheter emplacement was found in five cases, which suggested that this procedure using the standard burr hole site and aim point might result in incorrect catheter placement. The ideal external aim points were widely distributed because of the variable heights of ventricular structures from the cranial baseline. No correlation between the locations of the anatomical points and ventricular size was found. The present study could not define a standard external aim point. Tailored preoperative planning of the trajectory is recommended.

“…These data indicate that in normal aging, structural brain changes may be more salient than biochemical Recent computed tomography (CT) studies of brain structure in vivo in normal human aging have consistently indicated age-related changes (Barron et aI. , 1976;Glydensted and Kosteljanetz, 1976;Hahn and Rim, 1976;Jacoby et aI. , 1980;Yama· mura et aI.…”

Summary: Young normal subjects, old normal subjects, and patients with senile dementia of the Alzheimer's type (SDAT) were studied with both computed tomography (CT) and positron emission transaxial tomography (PETT). Increases in ventricular size with both aging and disease were measured. Regional glucose metabolic rate was not affected by age, but was markedly reduced in SDAT pa tients. These data indicate that in normal aging, structural brain changes may be more salient than biochemical Abbreviations used: CM, Canthomeatal; CT, computed to mography; FDG, 18F-2-deoxy-2-fluoro-D-glucose; GDS, Global Deterioration Scale; PETT, positron emission transaxial tomog raphy; SDAT, senile dementia of the Alzheimer's type. It is possible that a number of methodological variables, such as subject selection criteria and methods of scan analysis, may account for these
